Step 101 receives information input from touch screen.
When the user need to amplify the picture of the current demonstration of touch screen terminal, during reduction operation, carry out clicking operation at touch-screen; So-called clicking operation, origin coordinates that namely should operation be with to stop coordinate identical, and at the push of clicking with lift between the operation and do not move.The user touch-screen carry out be operating as clicking operation the time, the information input from touch screen that touch screen terminal receives is click information.Certainly, the operation that the user carries out at touch-screen can also be for slide etc., and during for slide, the information input from touch screen that touch screen terminal receives is slip information, this slip information comprises reference position and the final position of slip, and this moment, reference position was not identical with final position.
Step 102, when described information input from touch screen is click information, judge that according to the origin coordinates that comprises in the information input from touch screen this origin coordinates whether in highlighted position coordinates scope, if so, then carries out showing after amplifieroperation or the reduction operation to the picture of current demonstration.
In this step, namely can carry out the picture of current demonstration showing behind the amplifieroperation, also can carry out the picture of current demonstration showing after the reduction operation.If this step is for carrying out amplifieroperation to the picture of current demonstration, the origin coordinates that then comprises in judging information input from touch screen is in highlighted position coordinates scope the time, and the picture of current demonstration is carried out showing after the reduction operation; If this step is for carrying out reduction operation to the picture of current demonstration, the origin coordinates that then comprises in judging information input from touch screen is in highlighted position coordinates scope the time, and the picture of current demonstration is carried out showing behind the amplifieroperation.
Picture to current demonstration carries out amplifieroperation and reduction operation, can adopt existing techniques in realizing.After zooming in or out operation, can centered by the center picture of current demonstration, show the picture after zooming in or out.
Further, the present invention can also carry out slide to the picture of the current demonstration of touch screen terminal based on highlight regions, particularly, in the step 102 of Fig. 1 flow process, when described information input from touch screen is slip information, determine glide direction according to origin coordinates and termination coordinate that described slip information comprises, and judge that according to the origin coordinates that comprises in the information input from touch screen this origin coordinates is whether in described highlighted position coordinates scope, if so, along described glide direction or against described glide direction the highlight regions in the touch-screen is carried out move operation; Otherwise, along described glide direction or against described glide direction the picture of current demonstration is carried out move operation.
Variant process below by the image processing method of Fig. 2,4,5,6 pairs of touch screen terminals of the present invention is illustrated, wherein, Fig. 2 is the example flow diagram that the present invention initially shows picture, to be the present invention amplify process flow diagram with reduction operation to the picture of current demonstration to Fig. 4, Fig. 5 is the process flow diagram that the present invention moves highlight regions in the picture of current demonstration, and Fig. 6 is the present invention carries out slide to the picture of current demonstration process flow diagram.
Among the present invention, picture is initially shown, comprise original image is carried out full frame adaptive demonstration and the highlight regions on the touch-screen is carried out local brightening showing.The implementation that picture is initially shown has multiple, here describe with example shown in Figure 2, suppose that highlight regions is border circular areas in this example, and pre-save the highlighted position coordinates scope of highlight regions on touch-screen, the flow process of Fig. 2 may further comprise the steps:
Step 201 calculates the size of original image being carried out full frame adaptive demonstration.
The size of full frame adaptive demonstration comprises the width and the height that original image are carried out full frame adaptive rear shown picture.
This step specifically comprises: the ratio of width to height of original image and the ratio of width to height in touch-screen Image Display zone are compared, if the ratio of width to height of original image more than or equal to the ratio of width to height of touch-screen viewing area, then match width is highly placed in the middle; If the ratio of width to height of original image is less than the ratio of width to height of touch-screen viewing area, match height then, width is placed in the middle.So-called " match width " namely, take the width of the touch-screen viewing area width as full frame adaptive rear shown picture, then, calculates the height of the picture of full frame adaptive rear demonstration according to the ratio of width to height of original image.So-called " match height " namely, take the height of the touch-screen viewing area height as full frame adaptive rear shown picture, then, calculates the width of the picture of full frame adaptive rear demonstration according to the ratio of width to height of original image.
For example, the resolution of original image is 800 pixels * 600 pixels, need to be presented on the touch display screen of 480 pixels * 320 pixels:
The ratio of width to height of original image is: 800/600=4/3, and the ratio of width to height in touch-screen Image Display zone is: 480/320=3/2; Because 4/3 less than 3/2, match height then, width is placed in the middle, and like this, the height of the picture of full frame adaptive rear demonstration is the height of display screen, namely 320, the width of the picture of full frame adaptive rear demonstration is: 320*4/3 approximates 427 after rounding.Therefore the photo resolution of full frame adaptive rear demonstration is 427*320; The display screen width is unnecessary (480>427) in addition, for attractive in appearance, can Show Picture between two parties by width.
Step 202 is decoded as original image the size of the full frame adaptive demonstration that calculates in the step 201, obtains decoded picture.
Particularly, this step can adopt interpolation algorithm to realize, the method that adopts interpolation algorithm that picture is decoded is prior art, does not give unnecessary details here.
Step 203 outputs to touch-screen with decoded picture and shows between two parties.
Step 204, in the picture to current demonstration, the image that shows in the highlighted position coordinates scope of touch-screen carries out highlighted processing.
The image that shows in the regional area to appointment on the touch-screen carries out highlighted processing, for well known to a person skilled in the art technology, does not give unnecessary details here.
The flow process of Fig. 2 can also represent with Fig. 3.
After flow process by Fig. 2 initially shows picture, can amplify the picture of current demonstration and reduction operation, Fig. 4 is an embodiment who amplifies with reduction operation, among this embodiment, the reference position of supposing click information is carried out amplifieroperation in highlight regions the time, and the reference position of click information is outside highlight regions the time, carry out reduction operation, particularly, the flow process of Fig. 4 may further comprise the steps:
Step 401 receives information input from touch screen.
This step is identical with step 101.
Step 402 when described information input from touch screen is click information, is judged this origin coordinates whether in highlighted position coordinates scope according to the origin coordinates that comprises in the information input from touch screen, and if so, then execution in step 403, otherwise execution in step 408.
Step 403 judges whether the picture of current demonstration has reached the maximum amplification threshold value, and if so, then execution in step 407, otherwise execution in step 404.
The maximum amplification threshold value is the value that touch screen terminal sets in advance, and is based on the times magnification numerical value of original image.
Step 404 is decoded as size after the enlargement factor with the picture of current demonstration, obtains decoded amplification picture.
When carrying out the picture amplification, both can amplify as the basis with original image, and also can amplify as the basis with the picture of current demonstration, the method for two kinds of picture amplifications is similar, and the below is to amplifying explanation with original image as the basis.
Carry out picture when amplifying, adopt all fixedly in the time of can be according to a touch-screen of every click that multiple amplifies, also can set successively from small to large the multiple of amplification until picture enlargement factor threshold value.For example, the maximum amplification threshold value is 8, can all carry out 2 times of modes to the size that initially Shows Picture according to touch-screen of every click and amplify, until be amplified to 8 times to the size that initially Shows Picture; Perhaps, setting in advance the multiple that amplifies successively picture, for example is 2,6,8, when then clicking for the first time, the picture that initially shows is enlarged into 2 times to the size that initially Shows Picture, when clicking for the second time, the picture of current demonstration is enlarged into 6 times to the size that initially Shows Picture, when clicking for the 4th time, the picture of current demonstration is enlarged into 8 times to the size that initially Shows Picture, when clicking operation is carried out again in the back, owing to being amplified to the maximum amplification threshold value, then do not carrying out amplifieroperation.
Step 405, centered by the center picture of current demonstration, the viewing area of picture after determining to amplify.
Step 406, the decoded picture of output in the viewing area of determining.
Particularly, this step is: the decoded amplification picture that output step 404 obtains in the viewing area that step 405 is determined.
Step 404 can be passed through existing techniques in realizing to 406 methods for the picture of current demonstration being carried out show behind the amplifieroperation.
Step 407, amplifieroperation failure, process ends.
Step 408 judges whether the picture of current demonstration has reached the size that initially Shows Picture, and if so, then execution in step 411, otherwise execution in step 409.
The described size that initially Shows Picture of this step is namely carried out the picture size that shows after the flow process shown in Figure 2.
Step 409 is decoded as size behind the minification with the picture of current demonstration, obtains the decoded picture that dwindles.
When the picture of current demonstration is dwindled, adopt all fixedly in the time of can be according to a touch-screen of every click that multiple dwindles, also can set successively the multiple that dwindles from big to small until the size that initially Shows Picture.
Step 410 centered by the center picture of current demonstration, determines to dwindle the viewing area of rear picture, and then execution in step 406.
Here, during execution in step 406, be specially: the decoded picture that dwindles that output step 409 obtains in the viewing area that step 410 is determined.
Picture for current demonstration is through mobile situation, then the picture of current demonstration is not placed in the middle in the touch-screen viewing area, in this case, when decoding picture wide or high narrows down to less than touch-screen screen wide or high, the image content that can occur showing has part to exceed the situation at edge, touch-screen viewing area, picture can be shown between two parties this moment, to optimize the display effect of picture.
Step 411, reduction operation failure, process ends.
If the picture of current demonstration has reached the size of initial demonstration figure, then no longer carry out reduction operation.
Step 408 is to step 410, and step 406 can be passed through existing techniques in realizing for the picture of current demonstration being carried out the method for reduction operation.
After flow process by Fig. 2 initially shows picture, can mobile highlight regions, Fig. 5 carries out the embodiment that highlight regions moves, and among this embodiment, supposes the circle that is shaped as of highlight regions, and the flow process of Fig. 5 may further comprise the steps:
Step 501 receives information input from touch screen.
This step is identical with step 101.
Step 502 when described information input from touch screen is slip information, is judged this origin coordinates whether in highlighted position coordinates scope according to the origin coordinates that comprises in the information input from touch screen, and if so, then execution in step 503, otherwise execution in step 507.
Step 503 is determined highlighted position coordinates scope after circular highlight regions is upgraded according to slip information.
This step specifically comprises:
Determine glide direction according to origin coordinates and termination coordinate that slip information comprises, described origin coordinates and termination coordinate can be known by the slip sampling point information.Then, determine the new coordinate position of circular highlight regions in glide direction, for example, can will stop coordinate and be defined as the center of circular highlight regions, thereby, determine the coordinate position of circular highlight regions; For another example, can take Adjustment of sensitivity mechanism to determine the new coordinate position of circular highlight regions, so-called Adjustment of sensitivity mechanism, namely the size of slide displacement becomes certain ratio with highlight regions displacement size, like this, by the start-stop coordinate with after stopping coordinate and determining the size of sliding position, just can calculate the size of highlight regions displacement in conjunction with described ratio, thereby, determine the new coordinate position of highlight regions, such as, described ratio is 2, the slide displacement of determining is 2cm, and then highlight regions along the displacement that glide direction moves is: 2/2=1cm.Except along glide direction the highlight regions in the touch-screen being carried out the slide, can also carry out slide to the highlight regions in the touch-screen against glide direction; Against the method that glide direction is slided to highlight regions, similar with the method for highlight regions being slided along glide direction, just glide direction is opposite.
Step 504 judges whether the new coordinate position of circular highlight regions of determining exceeds the edge that touch-screen Shows Picture, and if so, then execution in step 505, otherwise execution in step 506.
This step is that this step is optional for the further effect that Shows Picture at touch-screen of optimizing.
Step 505 is adjusted the new coordinate position of circular highlight regions of determining, and makes it not exceed the edge that touch-screen Shows Picture.
Particularly, this step can the coordinate position that circular highlight regions is new be adjusted into just in time the side edge that Shows Picture with touch-screen and touches.
Step 506 is carried out highlighted demonstration with the image in the highlighted position coordinates scope after the circular highlight regions renewal after adjusting, and all the other zones are shown according to normal brightness.
Like this, just, realized the movement to highlight regions.
Step 507 is slided to the picture of current demonstration.
Particularly, this step can be by the flow process realization of Fig. 6, and Fig. 6 may further comprise the steps:
Whether step 601 judges the decoding picture size of picture of current demonstration greater than the touch-screen viewing area, and if so, then execution in step 602, otherwise execution in step 603.
Before touch-screen Shows Picture, need to obtain first decoding picture, and then decoding picture is presented in the touch-screen viewing area.
If the size of decoding picture greater than the touch-screen viewing area, then can move the picture of current demonstration, to show the image of decoding picture other parts; For example, the picture width of current demonstration then can by the operation of sliding or sliding, carry out move left and right to picture left to the right greater than the touch-screen width; For another example, the picture height of current demonstration then can by the operation of down sliding or upward sliding, move up and down picture greater than the touch-screen height.If the size of decoding picture is less than or equal to the touch-screen viewing area, then need not the picture of current demonstration is moved.
Step 602, the origin coordinates that comprises according to slip information and stop coordinate and determine glide direction carries out move operation, process ends along glide direction or against glide direction to the picture of current demonstration.
Along glide direction or against glide direction to the displacement size that the picture of current demonstration moves, can be the displacement size of slide, the termination coordinate that is namely comprised by slip information deducts the resulting absolute value of origin coordinates; Also can be by taking Adjustment of sensitivity mechanism to determine, so-called Adjustment of sensitivity mechanism, the namely displacement of slide size becomes certain ratio with picture displacement size, like this, by the start-stop coordinate with after stopping coordinate and determining the displacement size of slide, just can calculate the size of picture displacement in conjunction with this ratio.
Further, for prevent to picture move excessive and surpass on the touch-screen final show for blank, and do not have image content, in this case, can adjust the picture after the movement, so that the last picture that shows does not exceed edge, touch-screen viewing area.
Along the figure glide direction picture of current demonstration is carried out move operation, can adopt existing techniques in realizing, exceed here and give unnecessary details.
Step 603 is not carried out slide, process ends to the picture of current demonstration.
