Description
MANUALLY CONTROLLED INPUT DEVI OE FOR A COM~Ul~
The invention relates to a m,7n~7~l1y controlled input device (air brush) for a computer according to the preamble of Claim 1.
Mechanical air brushes are known and have five operating parameters, specifically the spatial position with respect to the surface to be sprayed in the X-, Y-, and Z-coordinates, as well as the air pressure of the spray jet and the amount of in~ situated in the spray jet, the two latter parameters typically being operated by a combined lever which can control both parameters independently of one another. Up to now, a mechanical air brush could be implemented on the computer and used only by special soft~are, in which case, however, only a partial area of the function of a mechanical air brush can be simulated.
For the software implementation, a portion of these above-described five parameters - specifically the dynamically changeable operating parameters - are inputted by a "computer mouse~ or a graph tablet, while the other parameters - specifically the static operating parameters - must be fixedly set before the use of the air brush function and can therefore no longer be changed during the processing.
- ' 21~3067 On the basis of European Patent Document EP 0 497 598 A2, an electronic, manually operated small-size spraying device has become known which may also be called a mechanical device per se, has a m~ml~l adjusting element for the air pressure to be adjusted and is provided with an air pressure sensor at the current outlet.
From U.S. Patent Document US-PS 4 751 503, a digital air brush device is known which can vary specific image portions with respect to their contrasts. A dynamic and independent change of all five parameters is not possible by means of these two devices.
It is an object of the present invention to provide an electronic input device of the initially mentioned type by means of which all five operating parameters -comprised by a mechanical air brush - can be changed dynamically and independently of one another during the operation.
This object is achieved by means of the measures lndicated in Claim 1. The subclaims indicate developments and further developments, and embodiments are described in the following description and illustrated in the figures of the drawings, in which case these figures also supplement the detailed explanations.

Figure 5 is a schematic view of the lever function of an air brush with the indication of the degrees of freedom of movement;
Figure 6 is a perspective view of an electronic air brush during the processing of a monitor image.
As illustrated in Figure 1 in an embodiment, an electronic air brush 10 - according to an embodiment of Figure 2 - is connected with a computer system C, as illustrated separately in Figure 3, by way of three interfaces, specifically the interfaces 16 and 21, the synchronization analysis 17 of the air brush 10 with the electronic module for the graph card 26 of the computer 2ls3~67 C, and its monitor 24 with the air brush lens system 11 of the air brush 10. By means of an optical scanning of the computer monitor 24 by means of the air brush lens system 11, the coordinates of the air brush 10 are determined in view of the computer monitor video screen 24. This first connection therefore takes place optically. For the determination of the absolute coordinates, the air brush 10 is connected with the video signal of the computer graph card 26 by way of the video synchronization analysis unit 17. This second connection therefore takes place physically. The computed coordinates and the adjusting values of the input lever 12 are transmitted by way of the interface 16 to the interface 21 of the computer C. This third connection therefore also takes place physically.
A computer C which is suitable for the use of an electronic air brush 10 is composed of the following modules or systems: A computer 22, a user program 23, a graph card 26 with a connected computer monitor video screen 24 and finally the graphic display input device 25 with the air brush 10 itself. For the processing of images by means of the user program 23, different tools are available to the user. One of these tools is, for example, an air brush application which has the purpose of spraying portions of images, which are partially covered by masks, with an ink so that a certain desirable effect is achieved.
The embodiment described in the following relates specifically to user programs 23 which are used for graphic changes of images. When a user activates the air brush tool in the program 23 , a specific subprogram is called which establishes the communication with the air brush 10 and carries out the changes of the image which are caused by the air brush data.
Starting with this condition, the previous function of the computer mouse or of the graph card or similar input devices is completely replaced by the air brush.
The user takes the air brush from the holder 13, whereby the latter is automatically activated. When it is now held in front of the computer monitor video screen, the air brush lens system 11 will detect the image dots of the computer monitor 24 which are made luminous by the deflected electron beam of the image tube. By means of the synchronization signals from the synchronization analysis unit 17, which are taken from the video signal, the computer 15 will now calculate the center point of the image of the air brush lens system 11 on the computer monitor video screen 24 or its surface. The imaging of the image dots by the lens system 11 is proportional to position x,y and distance z of the air brush 10 with respect to the computer monitor 24.
The determined coordinates (x,y,z) are transmitted by way of interface 16 to 21 to the computer 22 and thus 21~3067 to the user program 23. This program draws a marking cross at point x,y which is used for the position acknowledgement for the user. The distance z of the air brush 10 from the computer monitor 24 is characterized by the circle around the marking cross which corresponds to the imaging of the air brush lens system 11. When the user now operates the combined input lever 12, the corresponding pressure and ink quantity data are transmitted corresponding to the lever position ~alues to the user program 23. As a result, the electronic unit for the user program 23 causes the drawing of an ink set by the user to the image area defined by x, y, z. In this case the parameters air pressure and ink quantity are now taken into account.
If, during the operation of the input lever 12 or levers 12, the air brush 10 is moved into an arbitrary direction or the lever position is changed, the user program 23 is immediately informed of the new coordinates or the lever position values. Corresponding to the arriving data, the electronic unit for this program 23 enters the ink into the image to be processed and updates the marking.
When the desired ink application is terminated and the user deposits the air brush 10 back on the holder 13, the air brush is deactivated, the air brush subprogram is exited and the control is given back to the computer mouse or the graphic display input unit 25 for the normal further processing of the user program 23.
As mentioned above, the coordinates are determined from the imaging of the air brush lens system 11 with respect to the computer monitor video screen 24. By means of the synchronization analysis unit 17, the horizontal synchronization pulse (H sync pulse) for every line and the vertical synchronization pulse (V sync pulse) for every image are determined from the video signal which is generated by the graph card 26. By means of the V sync pulse, the y-counter 14a, which is used for the determination of the y-coordinate, is set back. By means of each H-sync pulse, the counter 14a is increased by 1. If, in line n, an image dot which is to be processed is determined by the air brush lens system 11, the current count of the y-counter 14ais stored in the computer 15.
The x-counter 14b, which is used for determ; nl ng the x-coordinate, is set back by means of each H sync pulse and is increased by means of a fixed timing frequency.
If, in the detection range of the air brush lens system 11 in the current line n, an image dot to be processed is detected, the x-counter 14b is stopped. At the end of the line, the x-count 14b is read by the computer 15 and is stored. At the end of an image, the computer 15 computes the center point of the imaging from the distribution of the stored x- and y-counts (see Figure 4).
From the number of lines, which are determined by the air brush lens system 11 per image, a conclusion can be drawn concerning the distance z of the lens system 11 from the computer monitor surface 24. The distance z is caused by the optical imaging proportional to the number of detected lines.
For determining the air pressure and the ink quantity, one path sensor 14c, 14d respectively is connected to the corresponding input lever 12 with its combined functions. By the pressing or releasing of the input lever 12, a change of the output signal of the path sensor 14c is caused which is analyzed and inputted into the computer 15. The output signal of the path sensor 14c is proportional to the push-in depth and, with respect to the value, results in the air pressure. The same principle is used for determining the amount of ink.
By the pulling or releasing of the input lever 12, a change of the output signal of the path sensor 14d is caused which is analyzed and transferred to the computer.
The output signal of the path sensor 14d is proportional to the adjusting path and, with respect to the value, results in the ink quantity.
21~3067 Figure 5 is a schematic representation of the functions of the input lever 12. Thus, an electronic air brush concept is indicated which no longer requires the previously necessary prerequisites, such as compressed air, ink and paper for its operation and is therefore environmentally friendly since it has no harmful effect on the health caused by ink spraying fog; because it no longer requires compressors; and because its handling is significantly simplified and mainly also much faster.
Figure 6 represents a significantly simplified system and illustrates its method of operation to the person skilled in the art.
