With further reference to Fig. 2, it illustrates the flow process 200 of another embodiment of the picture display process for mobile terminal.
As shown in Figure 2, in step 201, the screen display scope whether current display frame exceeds terminal is detected.In the present embodiment, this step is identical with above-mentioned steps 101, does not repeat them here.
Then, in step 202., if exceed the screen display scope of terminal, then the translation information of monitoring terminal.
In the present embodiment, when detecting that in above-mentioned steps 201 current display frame exceeds the screen display scope of terminal, then the translation information of monitoring terminal.In the present embodiment, translation information can comprise horizontal and vertical translation information, wherein, horizontal and vertically can refer in the plane at terminal screen place, orthogonal both direction.Usually, can the direction of two of a rectangle screen adjacent side be set to horizontal and vertical respectively.Particularly, when the translation information of monitoring terminal, the translation information of terminal in horizontal and vertical both direction can be obtained respectively.Can comprise displacement and the moving direction of terminal in translation information, wherein, moving direction refers to that terminal is along moving direction to the left or to the right during transverse shifting, or moving direction up or down when terminal moves along the longitudinal.
In an optional implementation of the present embodiment, translation information can also comprise vertical translation information.In the present embodiment, vertical translation information may be used for describing the situation of movement of terminal on normal to screen direction.Usual user, when observing the picture that terminal shows, can not make terminal in vertical direction strenuous exercise occur.Such as, but at some in particular cases, when user's hand-held mobile terminal is in walking states, the position of mobile terminal itself plays pendulum.Now, in order to avoid the strong shake of picture, the display position of picture can not also be adjusted.
According to epimere content, alternatively, at the present embodiment in the picture display process of mobile terminal, can also comprise:
Step 203, determines whether according to vertical translation information the display position adjusting picture.
In the present embodiment, if acquire the vertical translation information of terminal in above-mentioned steps 202, then only can determine whether according to the displacement in vertical translation information or moving direction the display position adjusting picture further.Such as, when moving direction does not all change in certain hour section, illustrate that terminal continues in vertical direction mobile.Now, can think that the display position be not suitable for picture adjusts.
In an optional implementation of the present embodiment, determine whether that the display position adjusting picture comprises according to vertical translation information: if the displacement in vertical translation information is less than or equal to the first distance threshold, then determine the display position adjusting picture.Particularly, if the displacement in vertical translation information is less than or equal to the first default distance threshold, then illustrate that terminal displacement is in vertical direction less.Now be applicable to adjusting the display position of picture, therefore can determine the display position adjusting picture, thus perform step 204.Otherwise, again obtain the vertical translation information of terminal, and again perform step 203.
Finally, in step 204, respectively based on horizontal and vertical translation information, the horizontal and vertical display position of adjustment picture.
In the present embodiment, when obtaining the horizontal and vertical translation information of terminal in above-mentioned steps 202, or alternatively, determine the display position of adjustment picture in above-mentioned steps 203 after, according to the lateral display positions of transverse translation information adjustment picture, and longitudinal display position of picture can be adjusted according to longitudinal translation information.Particularly, can according to the displacement in transverse translation information and moving direction, the lateral display positions of adjustment picture.Meanwhile, can according to the displacement in longitudinal translation information and moving direction, longitudinal display position of adjustment picture.It should be noted that, when the display position based on the displacement of terminal and moving direction adjustment picture, the displacement of picture is exactly the displacement of terminal, and the moving direction of picture and the moving direction of terminal be opposite direction each other.
In an optional implementation of the present embodiment, respectively based on horizontal and vertical translation information, the horizontal and vertical display position of adjustment picture comprises: when the displacement in transverse translation information is greater than second distance threshold value, according to the displacement in transverse translation information and moving direction, the lateral display positions of adjustment picture.When the displacement in longitudinal translation information is greater than the 3rd distance threshold, according to the displacement in longitudinal translation information and moving direction, longitudinal display position of adjustment picture.Particularly, before the lateral display positions of adjustment picture, first can judge whether the displacement in transverse translation information is greater than second distance threshold value.If displacement is greater than second distance threshold value, then can thinks that terminal has carried out transverse translation, so can carry out moving image according to the displacement in transverse translation information and moving direction further, to adjust the lateral display positions of picture.Otherwise, if displacement is less than second distance threshold value, then can think that terminal does not carry out transverse shifting, and the regular dither occurred when being likely user's handheld terminal, therefore determine not adjust the display position of picture.In like manner, according to the displacement in longitudinal translation information and the magnitude relationship between the 3rd distance threshold, the longitudinal display position adjusting picture can be determined whether.It should be noted that, the concrete numerical value of above-mentioned second distance threshold value and the 3rd distance threshold, can by user's sets itself according to the actual requirements, the value of the two can be identical, also can be different, and the application does not limit this.
As can be seen from Figure 2, the present embodiment has described in further detail when offset information comprises translation information, for the example implementations of the picture display process of mobile terminal.Whether the present embodiment the picture of the first current display of sense terminals can exceed the indication range of its screen, if exceeded, then monitors the translation information of this terminal, and according to this translation information adjustment picture display position on a terminal screen.By carrying out translation to mobile terminal, can change the display position of picture in terminal, this mode of operation simple, intuitive, optimizes the operating efficiency to terminal picture further.
In order to understand the scheme of the present embodiment better, Fig. 3 shows the application scenarios schematic diagram of the application.In the scene shown in Fig. 3, terminal 301 is smart mobile phone.For the ease of explaining to the translation direction in the present embodiment, first can set up cartesian coordinate system in the plane at the screen 302 of terminal 301, wherein, x-axis represents laterally, and y-axis represents longitudinally, and z-axis represents vertical direction.After user enables screen magnifying function in terminal 301, just current for terminal 301 shown picture 303 can be amplified, make it exceed the indication range of screen 302.Now, with the situation of movement of preset frequency (such as 1 time/second) acquisition terminal on x, y and z axes three directions, displacement and moving direction can be comprised.Then, first can judge whether the displacement of terminal 301 in z-axis is less than or equal to predetermined threshold value.If so, then according to the displacement of terminal 301 in x-axis and y-axis, picture 303 is moved.Such as, terminal 301 moves 1 centimetre along x-axis positive dirction, and moves 2 centimetres along y-axis negative direction simultaneously, then picture 303 can be moved 1 centimetre along x-axis negative direction, and moves 2 centimetres along y-axis positive dirction simultaneously.
With further reference to Fig. 4, it illustrates the flow process 400 of another embodiment of the picture display process for mobile terminal.
As shown in Figure 4, in step 401, the screen display scope whether current display frame exceeds terminal is detected.In the present embodiment, this step is identical with above-mentioned steps 101, does not repeat them here.
Compared with the embodiment shown in Fig. 1, the present embodiment monitoring be the spin information of terminal.Alternatively, before monitoring spin information, step 402 can also be comprised.
Particularly, in step 402, according to the spin reference position of preset rules determination terminal.
In the present embodiment, after determining that picture exceeds the indication range of terminal screen, can first according to certain preset rules, for terminal determines reference position of spinning.Such as, terminal screen as spin reference position, or can become position time certain degree (as 45 degree) as reference position of spinning by position when terminal screen can be in horizontality with ground level.
In an optional implementation of the present embodiment, the spin reference position according to preset rules determination terminal comprises: terminal is got the position of predetermined image as spin reference position.In the present embodiment, because each user uses the custom of terminal and different, angle when its handheld terminal is watched also is not quite similar.Therefore, can be the spin reference position of each user's setting individual, to improve the applicability of the present embodiment.Particularly, the front-facing camera of terminal can be got predetermined image, the face image of such as user or eye image etc., now can think that positive terminaloriented is observed, therefore can as the spin reference position of terminal.
Then, in step 403, if exceed the screen display scope of terminal, then the spin information of monitoring terminal.
In the present embodiment, when detecting that in above-mentioned steps 401 current display frame exceeds the screen display scope of terminal, then the spin information of monitoring terminal.In the present embodiment, spin information can comprise horizontal and vertical spin information, wherein, horizontal and vertically can refer in the plane at terminal screen place, orthogonal both direction.Usually, can the direction of two of a rectangle screen adjacent side be set to horizontal and vertical respectively.Particularly, when the spin information of monitoring terminal, the spin information of terminal in horizontal and vertical both direction can be obtained respectively.Spin angle and the spin direction of terminal can be comprised in spin information, wherein, transverse direction in spin direction refers to that terminal is around the clockwise or counterclockwise sense of rotation of longitudinal axis, and the longitudinal direction in spin direction refers to that terminal is around the clockwise or counterclockwise sense of rotation of lateral shaft.
If determine the spin reference position of terminal in above-mentioned optional step 402, then step 403A can be comprised in this step 403.
Particularly, in step 403A, based on above-mentioned spin reference position, the spin information of monitoring terminal.In the present embodiment, terminal, when monitoring spin information, can be set to reference position with above-mentioned spin base level all the time, determines spin angle and the spin direction of terminal.Thus make spin states all the time with same position for benchmark so that obtain the mobile message of picture by spin information.
Alternatively, the picture display process of the present embodiment can also comprise step 404.
Particularly, in step 404, according to the situation of change of spin information, the display position adjusting picture is determined whether.
In the present embodiment, if based on above-mentioned spin reference position in above-mentioned steps 403A, monitoring obtains the spin information of terminal, then further according to the situation of change of spin information, can determine whether the display position adjusting picture.Particularly, due to when spin occurs terminal, deflect for the terminal screen presenting picture, be not easy to user and observe image.In order to improve this problem, using spin reference position as optimum observation place, then according to the situation of change of spin information, the display position adjusting picture can be determined whether.Such as, when being turned on from spin reference position by spin information determination terminal, illustrating that user wishes to change picture position by terminal spin, then determining the display position adjusting picture; And when to be gone back to spin reference position from other positions by spin information determination terminal, illustrates that user wishes the picture after observing display position changes, then determine the display position not adjusting picture.That is, when terminal gets back to spin reference position from a certain position, image that still can be presented at this position, that pass through adjustment, instead of the initial pictures in spin reference position.Like this, not only by the display position of spin adjustment image, and solve from the deflection of supination screen, be unfavorable for the problem that user observes further increasing the practicality of this method.
In an optional implementation of the present embodiment, according to the situation of change of spin information, determine whether that the display position adjusting picture comprises: if the spin angle in spin information progressively increases progressively, then determine the display position adjusting picture.Particularly, when determining whether the display position adjusting picture, can not spin direction be considered, and only consider the situation of change of spin angle.If spin angle constantly increases, illustrate that terminal turns on from spin reference position gradually, also just can assert that user wishes to be changed by terminal spin the display position of picture.Otherwise, if spin angle constantly reduces, illustrate that terminal rotates back into spin reference position gradually from other positions, also just can assert that user wishes the picture after observing display position change.In this process, the display position not adjusting picture can just be determined.
Finally, in step 405, respectively based on horizontal and vertical spin information, the horizontal and vertical display position of adjustment picture.
When obtaining the horizontal and vertical spin information of terminal in above-mentioned steps 403, or alternatively, determine the display position of adjustment picture in above-mentioned steps 405 after, according to the lateral display positions of horizontal spin information adjustment picture, and longitudinal display position of picture can be adjusted according to longitudinal spin information.Particularly, can according to the spin angle in horizontal spin information and spin direction, the lateral display positions of adjustment picture.Meanwhile, can according to the spin angle in longitudinal spin information and spin direction, longitudinal display position of adjustment picture.It should be noted that, when the display position based on the spin angle of terminal and spin direction adjustment picture, the displacement of picture can be determined according to the spin angle of terminal, and the moving direction of picture can be determined according to the spin direction of terminal.
In an optional implementation of the present embodiment, respectively based on horizontal and vertical translation information, the horizontal and vertical display position of adjustment picture comprises: when the spin angle in horizontal spin information is greater than the first angle threshold, according to the spin angle in horizontal spin information and spin direction, the lateral display positions of adjustment picture; When the spin angle in longitudinal spin information is greater than the second angle threshold, according to the spin angle in longitudinal spin information and spin direction, longitudinal display position of adjustment picture.Particularly, before the lateral display positions of adjustment picture, first can judge whether the spin angle in horizontal spin information is greater than the first angle threshold.If spin angle is greater than the first angle threshold, then can thinks that terminal has carried out horizontal spin, so can carry out moving image according to the spin angle in horizontal spin information and spin direction further, to adjust the lateral display positions of picture.Otherwise, if spin angle is less than the first angle threshold, then can think that terminal does not carry out horizontal spin, and the regular dither occurred when being likely user's handheld terminal, therefore determine not adjust the display position of picture.In like manner, according to the spin angle in longitudinal spin information and the magnitude relationship between the second angle threshold, the longitudinal display position adjusting picture can be determined whether.It should be noted that, the concrete numerical value of above-mentioned first angle threshold and the second angle threshold, can by user's sets itself according to the actual requirements, the value of the two can be identical, also can be different, and the application does not limit this.
In an optional implementation of this example, according to above-mentioned spin angle and spin direction, the display position of adjustment picture can comprise: according to the displacement of spin angle and preset weights determination picture; According to the moving direction of spin direction determination picture; And according to displacement and moving direction, the display position of adjustment picture.When terminal spins, need the displacement according to spin angle determination picture.Particularly, can first preset a weights ξ, these weights can be determined according to historical experience, also can be determine according to the size of current picture.Such as, suppose that the transverse direction of picture is wide and be longitudinally highly respectively w and h, the spin angle maximal value of terminal is 90 degree, then horizontal weights ξ x can be w/90, and longitudinal weights ξ y can be h/90.The displacement picture offset distance of picture just can be determined according to following formula:
(dx,dy)＝(ξx·αx,ξy·αy)
Wherein, dx and dy be the displacement of representative picture on horizontal and vertical respectively, the horizontal and vertical spin angle of α x and α y GC group connector respectively.The moving direction of picture can determine according to the spin direction of terminal, specifically can by the relation in user's self-defining sense of rotation and picture moving direction, and such as, when can define clockwise direction spin, picture moves to forward.After the displacement determining picture and moving direction, just can adjust the display position of picture.
Although it should be noted that the operation describing the inventive method in the accompanying drawings with particular order, this is not that requirement or hint must perform these operations according to this particular order, or must perform the result that all shown operation could realize expectation.On the contrary, some step described in process flow diagram can change execution sequence.Such as, in the diagram, the execution sequence of step 402 can not specific to shown in Fig. 4, as long as before the spin information of step 403 monitoring terminal, step 402 determines spin reference position, does not just affect the realization of method for displaying image of the present invention.Additionally or alternatively, some step can be omitted, multiple step be merged into a step and perform, and/or a step is decomposed into multiple step and perform.
As can be seen from Figure 4, the present embodiment has described in further detail when offset information comprises spin information, for the example implementations of the picture display process of mobile terminal.Whether the present embodiment the picture of the first current display of sense terminals can exceed the indication range of its screen, if exceeded, then monitors the spin information of this terminal, and according to this spin information adjustment picture display position on a terminal screen.By spinning to mobile terminal, can change the display position of picture in terminal, this mode of operation is simply efficient, further expands the scope of application of the picture display process of the application.
In order to understand the scheme of the present embodiment better, equally for the application scenarios of the application shown in Fig. 3, illustrate.In the scene shown in Fig. 3, establish cartesian coordinate system in the plane at the screen 302 of terminal 301, wherein, x-axis represents laterally, and y-axis represents longitudinally.So, when obtaining the spin information of terminal, can using the spin around x-axis as longitudinal spin, and around the spin of y-axis as horizontal spin.Meanwhile, definition can be made to the relation between picture moving direction and spin direction.Such as, when observing along the negative direction of y-axis, if terminal 301 spins clockwise around y-axis, then picture can move along x-axis positive dirction, otherwise picture then moves along x-axis negative direction.Similarly, when observing along the positive dirction of x-axis, if terminal 301 spins clockwise around x-axis, then picture can move along y-axis positive dirction, otherwise picture then moves along y-axis negative direction.After being amplified by current for terminal 301 shown picture 303 by screen magnifying function, with the horizontal and vertical spin information of preset frequency (such as 5 times/second) acquisition terminal, spin angle and spin direction can be comprised.When spin angle increases progressively gradually, and when being greater than angle threshold 5 degree, then determine the display position adjusting picture.Particularly, if the spin angle that terminal 301 turns clockwise around y-axis, when being incremented to 30 degree gradually from 0, then picture 303 can calculate according to following formula along the distance dx of x-axis positive dirction movement:
dx＝ξx·αx＝(w/90)·30＝w/3
Wherein, ξ x is horizontal weights, and α x is the transverse direction spin angle of terminal 301, and w is the transverse width of picture 303.Now, if spin angle is decremented to 0 degree gradually from 30 degree, then the display position not adjusting picture is determined.Therefore, when terminal 301 rotates back into 0 degree, picture 303 still keeps along the state after x-axis positive dirction moves w/3.If terminal 303 repeats to return 0 degree from 0 degree to 30 degree again, then picture 303 can be in along the position after x-axis positive dirction moves 2w/3.In like manner, when terminal 301 is around y-axis counterclockwise spin, picture 303 can be moved along x-axis negative direction.It will be understood by those skilled in the art that the situation of terminal 301 when x-axis spins is similar with the situation when y-axis spins, do not repeat them here.
