Description
ELECTRONIC STILL CAUERA WIT~I AUDIO R~3CORDING F~ATIJRE
BAClE~GROlJND OF Tl~E INYE:NTIO~
The present invention relates generally to a `, 5 solid-state still image recording apparatus for picking up and recording still images, which apparatus is also capable of recording audio signals. More specifically, the invention relates to control of the solid-state still image recording apparatus with audio recording feature, for controlling recording of still images and o audio signals at a given timing.
Recently. electronic or solid-state cameras for picking up still images have been developed and put into the market. Such electronic cameras employ magnetic media or the like as a replacement for photographic film in recording still images. Hereafter.
` the wcrd ''video recording'' will be used to represent picking-up and recording still images on magnetic or equivalent recording media.
In order to make such solid-state still camera more attractive, it has been proposed to add audio recording features to the camera. In such cameras, it is possible to record audio sound related to the video recording, which is herèafter referred to as ''audio recording~', for a given period of time, e.g. lO sec.
Specifically, such cameras allow audio recording at a certain timing relative to the timing of video recording. The ability to record not onl~ still images but also audio sound. such as voice, would make these 0 cameras more attractive.
However, in cameras with both video and audio recording capability, it is difficult to properly set audio recording timing relative to video recording timing. This is inconvenient to the user since on different occasions, the user may want to perform video recording and audio recording at different times.
J
:
~ .
1 ~09 1 14 Therefore, it would be beneficial to provide some flexibility in selecting the timing relationship between video recording and audio recording so that the user can use this type of camera more conveniently.
~n the other hand, the camera can be equipped with a self-timing feature for performing video recording and audio recording in a manner similar to that of conventional film-type cameras. In this case, the timing relationship between video recording and audio r~cording becomes more critical. As is well known, such self-timers are generally used when the user of the camera wants to take his or her own picture. In such case, the user has to run to a predetermined position toward which the camera is directed after setting the self-timer. If the audio recording timing is set to start recording in response to onset of the sel-timer, the user's voice will not be recorded until the user has run into the directional reception range of a microphone built into in the camera. On the other hand, i.f the audio recording timing is set for a certain delay after onset of the self-timer, the above problem is avoided, but the selection of an appropriate delay time is very difficult, since the timing would be different for each individual user.
S~MMA~ OF T~E I~V~NTION

DESCRIPTIO~ OF T~E PREFERRED EMBODIME~T
Referring now to the drawings, particularly to Figs. 1 and 2, the preferred embodiment of a still camera 10 has an image pick-up system loo and an audio receiver system 200. The image pick-up system 100 includes a lens assembly 102 which focuses an image on an image receptacle comprising a charge transfer device, such as a charge-coupled device (CCD) 108, through a shutter mechanism 104. The shutter mechanism 104 0 controls exposure of the CCD 108 and therefore, is controlled by a shutter drive circuit to be opened and closed. On the other hand, the audio receiving system 200 includes a microphone 202 and a memory 206. The memory 206 comprises a digital memory ~or receiving pulse-code-modulated (PCM~ audio signals. In order to derive PCM signals from the output of the microphone 202, an analog-to-digital ~A/D) converter 204 is interposed between the microphone and the memory.
The camera 10 also has a disk drive unit 300 with a magnetic disk 302 serving as a video and audio recording medium. The image received by the CCD 108 and the PCM audio signals written in the memory 206 are transferred ~o and stored on the magnetic disk 302 by means of a video head 304 and an audio head 306 respectively. A recording controller 400 controls transfer of the image data from CCD 108 and PCM signals from the memory 206. The recording controller ~o0 generally compriees a video processor 402 and an audio recording circuit 404. The video processor 402 is connected for input from CC~ 208 via an amplifier 406 and is connected for output to the video head 304 via another amplifier 408.
It should be noted that a system for picking ~; up an image and recording video data for the picked-up image on the magnetic diskJ~ similar to the shown embodiment, has been disclosed in the British Patent 1 3~J9 1 7~
First Publication No. 2,112,603A, published on July 20, lg83 .
The video processor 402 and the audio recording circuit 404 coopera~e in order to synchronize storage of video data and the PCM signals to the magnetic disk 302 in the disk drtve.
The camera 10 also ~as a controller S00 for controlling operation o~ the ~mage pick-up system 100, the audio receiving system 200, and the disk dri~e unit 3Q0. ~e controller 500 lncludes a remote control sensor 502 wh~ch r~ceives remote control signals from a remote controller 6~0.
In the shown em~odiment, the remote controller 6Q0 transmits infrared rays which serve as the remote control signal. T~e ~nfrared rays emitted ~y the remote controller 600 may ~e modulated to represent a video recording demand and~or an audio recording demand.
Toward this end, the remote cont.roller 600 may emit di~ferent frequencies or dif~erent amplitudes of inf.rared li~ht for controlling ~ideo recording and audio recording i.ndependently, The controller 50Q ~as a pair of detectors 5Q4 ~nd 5Q6 connected for i~nput ~rom t~e remote control sensor 502 ~ia an amplifier 5Q8~ The detector 504 responds to the output o~ t~e remote control sensor 5Q2 ~ndicative of the video recording demand ~y outputting a de~ector signal to a ~ideo reco~d~ng controller 510.
T~.e ~ideo ~ecord~ng controller 51Q controls the shutter d~e circuit lQ6 ~c~ controls exposure timing and 3Q duxat~on. ~lso, ~.e ~ideo recording controller 510 controls t~e read-out ~tim~ng of t~e ~ideo data ~rom CCD
108 and the operat~on o a d~k dri~e motor 3Q8 in the disk dr~e unit 300, T~e ~ideo record~ng controller 510 ~u~ther controls read-out timing o~ PCM signals from the 7~
g memory 206 of the audio receiving system 200.
Hereafter, the control signal output from the video recording controller 510 for controlling the shutter drive circuit 106 will be referred to as ''shutter control signal Sc1~, that for controlling read-out timing of video data from the CCD will be i referred to as ~'video data read-out control signal Sc2~, that for controlling the disk drive motor will be referred to as ''disk drive control signal Sc3, and that o for controlling read-out timlng of the PCM signals from memory 206 will be referred to as ''PCM signal read-out control signal Sc4O
The detector 506 responds to a sensor output indicative of an audio recording demand by outputting a detector signal to a gate 512. The gate 512 is connected to a clock generator 514 in order to receive a ` clock signal 5t. The gate ~12 responds to the detector signal S06 by sending write-enable signal Sc5 to the memory 206 in order to allow storage of audio data in the form of PCM signals for a predetermined period of `; time, e.g. 10 sec, The clock generator 514 also sends the clock signal to another gate 516. The gate 516 is connected to the video recording controller ~lo to receive the PCM signal read-out control signal Sc4, whereupon it sends a read-enable signal Sc6 to the memory 206. In response to this read-enable signal Sc6, the stored audio data is transmitted to the audio recording circuit 404.
Although it has not been illustrated in the drawings, the video recording controller S10 may be associated with a shutter release button 12 built into the camera 10 and serving as a shutter button. The video recording control1er 510 may be responsive to depression of the shutter release button 12 to output the control signals Sc1 to Sc4 in substantially the same ` manner as when activated by the video recording ... .

controlling remote control signal from the remote contxoller. Furthermore, although not shown in the drawings, the camera may have an audio recording control button serving to trigger the gate 512 to enable storage 6 of audio data for the predetermined period of timeO
Alternatively, the gate 512 can be triggered by depression of the shutter release button 12. In this case, the shutter control signal Scl will be sent to the shutter drive circuit 106 after a given delay after issuance of the write-enable signal Scs. This delay time may be adjusted by means of a manually operable video-audio recording timing adjuster which may also be built into the camera 10.
As shown in Fig. 2, the remote controller 600 iS provided with an audio recording control button 602 and a video recording control button 604. The remote controller 600 is also provided with a mode selector switch 606 for switching operation mode between a MANUAL
mode and an AUTO mode. In MANUAL mode, the audio recording control button 602 and the video recording control button 604 can be operated independently of each other. Therefore, in the MANUAL mode, the audio recording timing and the video recording timing can be set as desired. On the other hand, in the AUTO mode, the audio recording control button 602 is disabled and only the video recording control button 604 is manually operable. In this case, audio recording timing and v.ideo recording timing are automatically controlled by provldinq a delay between the remote audio recording demand signal and the remite video recording demand signal. Preferably, an adjuster (not shown) in the remote controller 600 adjusts the delay between the output timing of the video recording demand infrared rays and the audio recording infrared rays.
It would al80 be advantageous to allow operation of the video recording button 604 while the audio recording button 602 is simultaneously depressed or alternatively within a given period of time after depression of the audio recording button 602. This ensures a good match between the audio sound and image upon reproduction. On the other hand, although the audio recording button 602 in the preferred embodiment set out above is disabled in AUTO mode, it would be possible to disable the ~ideo recording button and enable the audio recording button.
It should also be appreciated that, although not shown in the accompanying drawings, the camera lO
may be provided with a finder, a focusing mechanism associated with the lens assembly andlor an exposure control associated with the shutter mechanism. which are all well known in the field of film-type cameras.
The operation of the aforementioned preferred embodiment of the still camera according to the present invention will be described in more detail with reference to Figs. 3 to 5. It should be appreciated that Figs. 3 to 5 show diferent timings of audio recording and video recording.
Fig. 3 shows audio recording and video recording in a case where the video recording control bu~ton is depressed after expiration of the audio recording period, which begins in response to depression of the audio recording control button 602.
Specifically, at time tl, the audio recording button 602 is depressed until time t2, as shown in Fig. 3(A).
Therefore, during the period between tl and t2 9 infrared 30 light representing an audlo recording demand is transmitted by ~he remote controller 600. This audio recording demand signal is received by the remote contrcl sensor 502. The sensor output indicative of the audio recording demand is detected by the detector s06.
35 The dqtector ~06 then outputs the detector signal Sda to the gate 512. The gate 512 responds to the trailing ' edge or alternatively, the leading edge of the detector signal Sda by sending the write-enable signal Sc5 to the memory 206. At the same time, the gate 512 starts measuring elapsed time by counting the clock pulses from the clock generator 514. At time t3 at which the predetermined audio recording period, e.g. lo sec., expires, the gate 512 terminates the write-enabling signal Sc5.
It should be appreciated that the write-enabling signal Sc5 is sent to the memory in the form of clock pulse serving as a write clock pulse.
During the period t2 to t3, the memory 206 allows storage of the audio data. The audio data is received by the microphone ~02 as an analog audio signal Ss. The audio signal Ss is converted into PCM signals by the A/D converter 204 and input to the memory 206.
Therefore, in the presence of the write-enabling signal Sc5 in form of the write clock pulse. the PCM signals indicative of the audio data are stored in the memory 2G6 in a compressed time-base ~orm.
It would be pos~-ible to provide a certain response delay of the gate 512 to the detector signal Sda as shown by the broken line in Fig. 3~B). For this purpose, the gate 512 may be provided with a delay circuit responsive to each occurrence of the detector signal Sda. It would be pre~erable to allow adjustment of this delay by providing a delay time adjuster associated with the gate S12.
After completing storage of the audio data.
0 the video recording control button 604 is depressed at a time t4. The remote controller 600 transmits infrared rays representative of the video recording demand, as shown in Fig. 3(C). The detector S04 detects the video recording demands and outputs the detector signal Sdy.
The detector signal SdV is sent to the video-recording controller 510. The video-recording controller 510 is ,' . '. .
, , 1 ~09 1 74 responsive to the trailing edge of the detector signal SdV to output the disk drive control signal Sc3, at a time tS~ Then, the disk drive motor 308, which comprises a spindle motor, starts turning. After a predetermined period long enough to allow the motor of the disk drive motor 308 to come up to ~peed, the shutter control signal Sc1 is output to the shutter drive circuit 106, at a time t6. The shutter control signal Sc1 remains HIGH for a period of time 0 corresponding to the exposure duration of the shutter lQ~.
The exposure duration of the shutter may be derived manually or automatical~y according to the well known parameters. Therefore, the video-recording controller may derive the pulse width of the shutter control slgnal Sc1 according to the optimum exposure period.
While the shutter control signal Sc1 is HIGH, the sh~tter drive circuit 106 is active to hold the shutter 104 open and expose CCD to the image passing through the lens assembly 102. During this exposure period, CCD picks up one field or frame of image data.
In response to the trailiny edge of the shutter control signal Sc1, the video data read control signal SA2 is transmitter to CCD 108 from the video-recording controller 510, at a time t7. In response to the video data read control signal Sc2, the temporarily stored image data in CCD 108 is read out and sent to the video processor 402 via the amplifier 406.
At the same time, i.e. at the time t7, the audio data read control signal Sc~ is output by the video-xecording controller Slo to the gate 516. In responae to the audio data control signal Sc4, the gate sends the read-enable signal Sc6 in the fcrm of a read pulse to the memory 206. Therefore, the compressed audio data in the memory is read out and transmitted to .
the audio recording circuit 404.
The video processor 402 performs FM modulation of the video data signal and then sends the result to the video head 304 through the recording amplifier 408.
Likewise, the audio recording circuit 404 performs FM
modulation of the audio data signal and then transmits it to the audio head 306. The video data and audio data are writ~en onto the magnetic disk synchronously through the video head 304 and the audio head 30~.
o If desiredl storage of audio and video data on the magnetic disk 302 may be non-synchronous, as shown by the broken line in Fig. 3tG). In this case, the gate 516 may delay transmission of the read~enable signal Sc6 for a given delay time after receiving the audio data ~5 recording control signal Sc4. This non synchronous method of recording on magnetic disk enables video recording and audio recording by a common magnetic head.
In order to enable video recording and audio recording with a common head, it is preferable to allow a certain interval, e.g. 1l60 sec., between video recording and audio recording.
Figs. 4(A) to 4(G~ are similar to Figs. 3(A) to 3(G). However, in this case, the audio recording button 602 is depressed at a time labelled tlo and the video recording button 604 is depressed during the audio recording period, e.g. wi~hin 10 sec. of depression of the audio recording button.
, In this case, the audio recording demand signal is produced at the time tlo and terminates at a time tll. In response to the trailing edge of the detector signal Sda from the detector 506, the ; write-enabling signal Sc5 is transmitted from the gate 512 to the memory 206 to enable the latter to record the audio data received through the microphone 202 and converted into PCM~ signals by the A/D converter 204.
After a while, the video record1ng demand signal is ~' ., 130q~74 generated by the remote controller 600 in response to depression of the video recording button 604, at a time t12. In response to this, the detector signal SdV is output from the detector 504. In response to the trailing edge of the detector signal Sdv, the disk drive contjrol signal Sc3 is sent at time t13 to the disk drive spindle motor 308 to bring it up to speed. Once the disk drive is ready, i.e., at time t14, the shutter control signal Scl is ~ransmitted to the shutter drive 0 circuit 106 to operate the shutter mechanism 104.
In the shown example, the timing of depression of the video recording button 604 is sufficiently early to complete exposure of the CCD 108 before expiration of the audio recording period. Therefore, at a time t15, i.e., at the end of the shutter control signal S1, the video data read control signal Sc2 is transmitted to tge CCD, At the same time, the audio data read control signal Sc4 is transmitted from the video recording controller S10 to the gate 516. At the same time, the gate S~ a is stil outputting the write-enabling signal SC5, and it also sneds a disabling signal Sc7 to the gate 516 ~refer to Fig. 1). Therefore, despite the presence of the audio data read control signal, the audio data may not be read out of memory. At a time t16, the write-enabling signal Sc5, i.e., the audio recording period ends. At the same time. the disabling signal Sc7 for the gate 516 ends. As a result, the gate S16 is free to transmit the read-enable signal Sc6 to the memory 206. As a result, the audio data can be read from memory 206 after the time t16.~ Thus, the video data and audio data are written to the magnetic disk 302 at different times~
As mentioned above, the remote controller 600 s in the preferred embodiment of the invention allows not only MANUAL mode operation but also AUTO mode operation.
~ig. 5 shows an example of ~UTO mode operation.
:
/
1~0~174 The mode selector switch 606 is shifted to the AUT0 mode position to select AUTO mode. As a result, the audio recording button 602 is disabled. The remote controller 600 becomes active in response to depression of the video recording button 604 at a time t21. In this case, the remote controller 600 transmits the audio recording demand signal in response to depression of the video recording button. This initiates recording of audio data in memory 206 for the given period of time, 0 e.g. 10 sec, starting at time t22.
After a predetermined delay which may be manually adjustable as set forth above, the remote controller 600 transmits the video recording demand signal at a time t23. In response to this, video data 1~ is picked up by CCD 108.
It should be appreciated that the predetermined delay time has to be longer than the time needed to bring the disk drive motor 308 up to speed.
Therefore, the minimum delay time available to the manual adjusting means should be longer than the warm-up time of the disk drive motor.
The subsequent steps for transferring the audio and video data to the magnetic disk 302 from the memory 206 and CCD 108 are essentially the same as disclosed with respect to Fig. 4.

BAClE~GROlJND OF Tl~E INYE:NTIO~
The present invention relates generally to a `, 5 solid-state still image recording apparatus for picking up and recording still images, which apparatus is also capable of recording audio signals. More specifically, the invention relates to control of the solid-state still image recording apparatus with audio recording feature, for controlling recording of still images and o audio signals at a given timing.
Recently. electronic or solid-state cameras for picking up still images have been developed and put into the market. Such electronic cameras employ magnetic media or the like as a replacement for photographic film in recording still images. Hereafter.
` the wcrd ''video recording'' will be used to represent picking-up and recording still images on magnetic or equivalent recording media.
In order to make such solid-state still camera more attractive, it has been proposed to add audio recording features to the camera. In such cameras, it is possible to record audio sound related to the video recording, which is herèafter referred to as ''audio recording~', for a given period of time, e.g. lO sec.
Specifically, such cameras allow audio recording at a certain timing relative to the timing of video recording. The ability to record not onl~ still images but also audio sound. such as voice, would make these 0 cameras more attractive.
However, in cameras with both video and audio recording capability, it is difficult to properly set audio recording timing relative to video recording timing. This is inconvenient to the user since on different occasions, the user may want to perform video recording and audio recording at different times.
J
:
~ .
1 ~09 1 14 Therefore, it would be beneficial to provide some flexibility in selecting the timing relationship between video recording and audio recording so that the user can use this type of camera more conveniently.
~n the other hand, the camera can be equipped with a self-timing feature for performing video recording and audio recording in a manner similar to that of conventional film-type cameras. In this case, the timing relationship between video recording and audio r~cording becomes more critical. As is well known, such self-timers are generally used when the user of the camera wants to take his or her own picture. In such case, the user has to run to a predetermined position toward which the camera is directed after setting the self-timer. If the audio recording timing is set to start recording in response to onset of the sel-timer, the user's voice will not be recorded until the user has run into the directional reception range of a microphone built into in the camera. On the other hand, i.f the audio recording timing is set for a certain delay after onset of the self-timer, the above problem is avoided, but the selection of an appropriate delay time is very difficult, since the timing would be different for each individual user.
S~MMA~ OF T~E I~V~NTION

DESCRIPTIO~ OF T~E PREFERRED EMBODIME~T
Referring now to the drawings, particularly to Figs. 1 and 2, the preferred embodiment of a still camera 10 has an image pick-up system loo and an audio receiver system 200. The image pick-up system 100 includes a lens assembly 102 which focuses an image on an image receptacle comprising a charge transfer device, such as a charge-coupled device (CCD) 108, through a shutter mechanism 104. The shutter mechanism 104 0 controls exposure of the CCD 108 and therefore, is controlled by a shutter drive circuit to be opened and closed. On the other hand, the audio receiving system 200 includes a microphone 202 and a memory 206. The memory 206 comprises a digital memory ~or receiving pulse-code-modulated (PCM~ audio signals. In order to derive PCM signals from the output of the microphone 202, an analog-to-digital ~A/D) converter 204 is interposed between the microphone and the memory.
The camera 10 also has a disk drive unit 300 with a magnetic disk 302 serving as a video and audio recording medium. The image received by the CCD 108 and the PCM audio signals written in the memory 206 are transferred ~o and stored on the magnetic disk 302 by means of a video head 304 and an audio head 306 respectively. A recording controller 400 controls transfer of the image data from CCD 108 and PCM signals from the memory 206. The recording controller ~o0 generally compriees a video processor 402 and an audio recording circuit 404. The video processor 402 is connected for input from CC~ 208 via an amplifier 406 and is connected for output to the video head 304 via another amplifier 408.
It should be noted that a system for picking ~; up an image and recording video data for the picked-up image on the magnetic diskJ~ similar to the shown embodiment, has been disclosed in the British Patent 1 3~J9 1 7~
First Publication No. 2,112,603A, published on July 20, lg83 .
The video processor 402 and the audio recording circuit 404 coopera~e in order to synchronize storage of video data and the PCM signals to the magnetic disk 302 in the disk drtve.
The camera 10 also ~as a controller S00 for controlling operation o~ the ~mage pick-up system 100, the audio receiving system 200, and the disk dri~e unit 3Q0. ~e controller 500 lncludes a remote control sensor 502 wh~ch r~ceives remote control signals from a remote controller 6~0.
In the shown em~odiment, the remote controller 6Q0 transmits infrared rays which serve as the remote control signal. T~e ~nfrared rays emitted ~y the remote controller 600 may ~e modulated to represent a video recording demand and~or an audio recording demand.
Toward this end, the remote cont.roller 600 may emit di~ferent frequencies or dif~erent amplitudes of inf.rared li~ht for controlling ~ideo recording and audio recording i.ndependently, The controller 50Q ~as a pair of detectors 5Q4 ~nd 5Q6 connected for i~nput ~rom t~e remote control sensor 502 ~ia an amplifier 5Q8~ The detector 504 responds to the output o~ t~e remote control sensor 5Q2 ~ndicative of the video recording demand ~y outputting a de~ector signal to a ~ideo reco~d~ng controller 510.
T~.e ~ideo ~ecord~ng controller 51Q controls the shutter d~e circuit lQ6 ~c~ controls exposure timing and 3Q duxat~on. ~lso, ~.e ~ideo recording controller 510 controls t~e read-out ~tim~ng of t~e ~ideo data ~rom CCD
108 and the operat~on o a d~k dri~e motor 3Q8 in the disk dr~e unit 300, T~e ~ideo record~ng controller 510 ~u~ther controls read-out timing o~ PCM signals from the 7~
g memory 206 of the audio receiving system 200.
Hereafter, the control signal output from the video recording controller 510 for controlling the shutter drive circuit 106 will be referred to as ''shutter control signal Sc1~, that for controlling read-out timing of video data from the CCD will be i referred to as ~'video data read-out control signal Sc2~, that for controlling the disk drive motor will be referred to as ''disk drive control signal Sc3, and that o for controlling read-out timlng of the PCM signals from memory 206 will be referred to as ''PCM signal read-out control signal Sc4O
The detector 506 responds to a sensor output indicative of an audio recording demand by outputting a detector signal to a gate 512. The gate 512 is connected to a clock generator 514 in order to receive a ` clock signal 5t. The gate ~12 responds to the detector signal S06 by sending write-enable signal Sc5 to the memory 206 in order to allow storage of audio data in the form of PCM signals for a predetermined period of `; time, e.g. 10 sec, The clock generator 514 also sends the clock signal to another gate 516. The gate 516 is connected to the video recording controller ~lo to receive the PCM signal read-out control signal Sc4, whereupon it sends a read-enable signal Sc6 to the memory 206. In response to this read-enable signal Sc6, the stored audio data is transmitted to the audio recording circuit 404.
Although it has not been illustrated in the drawings, the video recording controller S10 may be associated with a shutter release button 12 built into the camera 10 and serving as a shutter button. The video recording control1er 510 may be responsive to depression of the shutter release button 12 to output the control signals Sc1 to Sc4 in substantially the same ` manner as when activated by the video recording ... .

controlling remote control signal from the remote contxoller. Furthermore, although not shown in the drawings, the camera may have an audio recording control button serving to trigger the gate 512 to enable storage 6 of audio data for the predetermined period of timeO
Alternatively, the gate 512 can be triggered by depression of the shutter release button 12. In this case, the shutter control signal Scl will be sent to the shutter drive circuit 106 after a given delay after issuance of the write-enable signal Scs. This delay time may be adjusted by means of a manually operable video-audio recording timing adjuster which may also be built into the camera 10.
As shown in Fig. 2, the remote controller 600 iS provided with an audio recording control button 602 and a video recording control button 604. The remote controller 600 is also provided with a mode selector switch 606 for switching operation mode between a MANUAL
mode and an AUTO mode. In MANUAL mode, the audio recording control button 602 and the video recording control button 604 can be operated independently of each other. Therefore, in the MANUAL mode, the audio recording timing and the video recording timing can be set as desired. On the other hand, in the AUTO mode, the audio recording control button 602 is disabled and only the video recording control button 604 is manually operable. In this case, audio recording timing and v.ideo recording timing are automatically controlled by provldinq a delay between the remote audio recording demand signal and the remite video recording demand signal. Preferably, an adjuster (not shown) in the remote controller 600 adjusts the delay between the output timing of the video recording demand infrared rays and the audio recording infrared rays.
It would al80 be advantageous to allow operation of the video recording button 604 while the audio recording button 602 is simultaneously depressed or alternatively within a given period of time after depression of the audio recording button 602. This ensures a good match between the audio sound and image upon reproduction. On the other hand, although the audio recording button 602 in the preferred embodiment set out above is disabled in AUTO mode, it would be possible to disable the ~ideo recording button and enable the audio recording button.
It should also be appreciated that, although not shown in the accompanying drawings, the camera lO
may be provided with a finder, a focusing mechanism associated with the lens assembly andlor an exposure control associated with the shutter mechanism. which are all well known in the field of film-type cameras.
The operation of the aforementioned preferred embodiment of the still camera according to the present invention will be described in more detail with reference to Figs. 3 to 5. It should be appreciated that Figs. 3 to 5 show diferent timings of audio recording and video recording.
Fig. 3 shows audio recording and video recording in a case where the video recording control bu~ton is depressed after expiration of the audio recording period, which begins in response to depression of the audio recording control button 602.
Specifically, at time tl, the audio recording button 602 is depressed until time t2, as shown in Fig. 3(A).
Therefore, during the period between tl and t2 9 infrared 30 light representing an audlo recording demand is transmitted by ~he remote controller 600. This audio recording demand signal is received by the remote contrcl sensor 502. The sensor output indicative of the audio recording demand is detected by the detector s06.
35 The dqtector ~06 then outputs the detector signal Sda to the gate 512. The gate 512 responds to the trailing ' edge or alternatively, the leading edge of the detector signal Sda by sending the write-enable signal Sc5 to the memory 206. At the same time, the gate 512 starts measuring elapsed time by counting the clock pulses from the clock generator 514. At time t3 at which the predetermined audio recording period, e.g. lo sec., expires, the gate 512 terminates the write-enabling signal Sc5.
It should be appreciated that the write-enabling signal Sc5 is sent to the memory in the form of clock pulse serving as a write clock pulse.
During the period t2 to t3, the memory 206 allows storage of the audio data. The audio data is received by the microphone ~02 as an analog audio signal Ss. The audio signal Ss is converted into PCM signals by the A/D converter 204 and input to the memory 206.
Therefore, in the presence of the write-enabling signal Sc5 in form of the write clock pulse. the PCM signals indicative of the audio data are stored in the memory 2G6 in a compressed time-base ~orm.
It would be pos~-ible to provide a certain response delay of the gate 512 to the detector signal Sda as shown by the broken line in Fig. 3~B). For this purpose, the gate 512 may be provided with a delay circuit responsive to each occurrence of the detector signal Sda. It would be pre~erable to allow adjustment of this delay by providing a delay time adjuster associated with the gate S12.
After completing storage of the audio data.
0 the video recording control button 604 is depressed at a time t4. The remote controller 600 transmits infrared rays representative of the video recording demand, as shown in Fig. 3(C). The detector S04 detects the video recording demands and outputs the detector signal Sdy.
The detector signal SdV is sent to the video-recording controller 510. The video-recording controller 510 is ,' . '. .
, , 1 ~09 1 74 responsive to the trailing edge of the detector signal SdV to output the disk drive control signal Sc3, at a time tS~ Then, the disk drive motor 308, which comprises a spindle motor, starts turning. After a predetermined period long enough to allow the motor of the disk drive motor 308 to come up to ~peed, the shutter control signal Sc1 is output to the shutter drive circuit 106, at a time t6. The shutter control signal Sc1 remains HIGH for a period of time 0 corresponding to the exposure duration of the shutter lQ~.
The exposure duration of the shutter may be derived manually or automatical~y according to the well known parameters. Therefore, the video-recording controller may derive the pulse width of the shutter control slgnal Sc1 according to the optimum exposure period.
While the shutter control signal Sc1 is HIGH, the sh~tter drive circuit 106 is active to hold the shutter 104 open and expose CCD to the image passing through the lens assembly 102. During this exposure period, CCD picks up one field or frame of image data.
In response to the trailiny edge of the shutter control signal Sc1, the video data read control signal SA2 is transmitter to CCD 108 from the video-recording controller 510, at a time t7. In response to the video data read control signal Sc2, the temporarily stored image data in CCD 108 is read out and sent to the video processor 402 via the amplifier 406.
At the same time, i.e. at the time t7, the audio data read control signal Sc~ is output by the video-xecording controller Slo to the gate 516. In responae to the audio data control signal Sc4, the gate sends the read-enable signal Sc6 in the fcrm of a read pulse to the memory 206. Therefore, the compressed audio data in the memory is read out and transmitted to .
the audio recording circuit 404.
The video processor 402 performs FM modulation of the video data signal and then sends the result to the video head 304 through the recording amplifier 408.
Likewise, the audio recording circuit 404 performs FM
modulation of the audio data signal and then transmits it to the audio head 306. The video data and audio data are writ~en onto the magnetic disk synchronously through the video head 304 and the audio head 30~.
o If desiredl storage of audio and video data on the magnetic disk 302 may be non-synchronous, as shown by the broken line in Fig. 3tG). In this case, the gate 516 may delay transmission of the read~enable signal Sc6 for a given delay time after receiving the audio data ~5 recording control signal Sc4. This non synchronous method of recording on magnetic disk enables video recording and audio recording by a common magnetic head.
In order to enable video recording and audio recording with a common head, it is preferable to allow a certain interval, e.g. 1l60 sec., between video recording and audio recording.
Figs. 4(A) to 4(G~ are similar to Figs. 3(A) to 3(G). However, in this case, the audio recording button 602 is depressed at a time labelled tlo and the video recording button 604 is depressed during the audio recording period, e.g. wi~hin 10 sec. of depression of the audio recording button.
, In this case, the audio recording demand signal is produced at the time tlo and terminates at a time tll. In response to the trailing edge of the detector signal Sda from the detector 506, the ; write-enabling signal Sc5 is transmitted from the gate 512 to the memory 206 to enable the latter to record the audio data received through the microphone 202 and converted into PCM~ signals by the A/D converter 204.
After a while, the video record1ng demand signal is ~' ., 130q~74 generated by the remote controller 600 in response to depression of the video recording button 604, at a time t12. In response to this, the detector signal SdV is output from the detector 504. In response to the trailing edge of the detector signal Sdv, the disk drive contjrol signal Sc3 is sent at time t13 to the disk drive spindle motor 308 to bring it up to speed. Once the disk drive is ready, i.e., at time t14, the shutter control signal Scl is ~ransmitted to the shutter drive 0 circuit 106 to operate the shutter mechanism 104.
In the shown example, the timing of depression of the video recording button 604 is sufficiently early to complete exposure of the CCD 108 before expiration of the audio recording period. Therefore, at a time t15, i.e., at the end of the shutter control signal S1, the video data read control signal Sc2 is transmitted to tge CCD, At the same time, the audio data read control signal Sc4 is transmitted from the video recording controller S10 to the gate 516. At the same time, the gate S~ a is stil outputting the write-enabling signal SC5, and it also sneds a disabling signal Sc7 to the gate 516 ~refer to Fig. 1). Therefore, despite the presence of the audio data read control signal, the audio data may not be read out of memory. At a time t16, the write-enabling signal Sc5, i.e., the audio recording period ends. At the same time. the disabling signal Sc7 for the gate 516 ends. As a result, the gate S16 is free to transmit the read-enable signal Sc6 to the memory 206. As a result, the audio data can be read from memory 206 after the time t16.~ Thus, the video data and audio data are written to the magnetic disk 302 at different times~
As mentioned above, the remote controller 600 s in the preferred embodiment of the invention allows not only MANUAL mode operation but also AUTO mode operation.
~ig. 5 shows an example of ~UTO mode operation.
:
/
1~0~174 The mode selector switch 606 is shifted to the AUT0 mode position to select AUTO mode. As a result, the audio recording button 602 is disabled. The remote controller 600 becomes active in response to depression of the video recording button 604 at a time t21. In this case, the remote controller 600 transmits the audio recording demand signal in response to depression of the video recording button. This initiates recording of audio data in memory 206 for the given period of time, 0 e.g. 10 sec, starting at time t22.
After a predetermined delay which may be manually adjustable as set forth above, the remote controller 600 transmits the video recording demand signal at a time t23. In response to this, video data 1~ is picked up by CCD 108.
It should be appreciated that the predetermined delay time has to be longer than the time needed to bring the disk drive motor 308 up to speed.
Therefore, the minimum delay time available to the manual adjusting means should be longer than the warm-up time of the disk drive motor.
The subsequent steps for transferring the audio and video data to the magnetic disk 302 from the memory 206 and CCD 108 are essentially the same as disclosed with respect to Fig. 4.
As will be appreciated herefrom. the present invention fulfills all of the objects and advantages sought therefor.
It should be appreciated that, while the invention has been disclosed in terms of the specific embodiment, various embodiments and modifications to the shown embodiment would~be possible without changing the significance of the inven~ion.
For example, although the microphone is installed in the camera in the shown embodiment. it would be possible to use a wireless microphone installed in the remote controller or independent of the camera and the remote controller.
Therefore. the invention should be understood to include all possible embodiments and modifications to the shown embodiment which do not depart from the principle of the invention, which is set out in the appended claims.
