Integrated mode among the image presentation method embodiment of the present invention is when comprising four split screen image models of four source images, synoptic diagram adaptive between source images and the target background is shown in Fig. 9 A and 9B: in Fig. 9 A and Fig. 9 B, wide and the height of source images 1 is respectively W1 and H 1, wide and the height of source images 2 is respectively W2 and H2, wide and the height of source images 3 is respectively W3 and H3, wide and the height of source images 4 is respectively W4 and H4, wide and the height of target background is respectively BackW and BackH, SubW1 and SubH1 are wide and high in target background of source images 1 after the uniform zoom, SubW2 and SubH2 are wide and high in target background of source images 2 after the uniform zoom, and SubW3 and SubH3 are wide and high in target background of source images 3 after the uniform zoom; SubW4 and SubH4 are wide and high in target background of source images 4 after the uniform zoom, and wherein the ratio of the ratio of the ratio of the ratio of BackW, BackH, W1 and H1, W2 and H2, W3 and H3, W4 and H4 is the parameter of input.
Wherein, wide equate (SubW1=SubW4) that pass between source images parameter shown in Fig. 9 A and the target background parameter is source images 1 and source images 4 uniform zoom in the target background, source images 2 and source images 3 uniform zoom wide equate (SubW2=SubW3) in the target background, wide after source images 1 and source images 2 uniform zoom and equal source images 3 and source images 4 uniform zoom after wide and (SubW1+SubW2=SubW3+SubW4), high after the uniform zoom high and that equal source images 2 and source images 3 after the uniform zoom of source images 1 and source images 4 and (SubH1+SubH4=SubH2+SubH3).Because the ratio of width to height of the picture that the image 1 after the uniform zoom, image 2, image 3, image 4 are synthetic is less than the ratio of width to height of target background, source images parameter that obtains thus and the pass between the target background parameter are the height (SubH1+Sub H4=BackH and SubH2+SubH3=BackH) that the high of source images 1 after the uniform zoom and source images 4 and (be the high of source images 2 after the uniform zoom and source images 3 and) equal target background.According to the SubW1 that calculates, SubH1, SubW2, SubH2, SubW3, SubH3, SubW4, SubH4 with source images 1, source images 2, source images 3, source images 4 uniform zoom in target background, shown in Fig. 9 A.
Wherein, pass between source images parameter shown in Fig. 9 B and the target background parameter is that source images 1 and source images 2 uniform zoom equate (SubH1=SubH2) to the height in the target background, source images 3 and source images 4 uniform zoom equate (SubH3=SubW4) to the height in the target background, high in the target background of wide in the target background of source images 1 and source images 2 uniform zoom and equal source images 3 and source images 4 uniform zoom wide in the target background and (SubW1+SubW2=SubW3+SubW4), source images 1 and source images 4 uniform zoom and equal source images 2 and source images 3 uniform zoom high in the target background and (SubH1+SubH4=SubH2+SubH3).Because the ratio of width to height of the picture that the image 1 after the uniform zoom, image 2, image 3, image 4 are synthetic is greater than the ratio of width to height of target background, source images parameter that obtains thus and the pass between the target background parameter are wide (SubW1+SubW2=BackW and the SubW3+SubW4=BackW) that the wide of source images 1 after the uniform zoom and source images 2 and (be the wide of source images 3 after the uniform zoom and source images 4 and) equal target background.According to the SubW1 that calculates, SubH1, SubW2, SubH2, SubW3, SubH3, SubW4, SubH4 with source images 1, source images 2, source images 3, source images 4 uniform zoom in target background, shown in Fig. 9 B.
The area of four source images after the uniform zoom that at last can be more respectively calculates according to Fig. 9 A and Fig. 9 B and, select the bigger combination image of area to export.
With four split screen image models be example image presentation method embodiment of the present invention the application structure synoptic diagram as shown in figure 10:
Source images optimal combination configurator reception sources image 1, source images 2, the ratio of width to height of source images 3 and source images 4, integrated mode four split screens of source images, and target background is wide, height and position (being the X coordinate and the Y coordinate in the target background upper left corner), can be the computing chip that has write in advance at the computing method of each integrated mode in the source images optimal combination configurator, call corresponding computing method according to integrated mode, calculate the uniform zoom parameter of each source images and the correspondence position in target background, source images optimal combination configurator is input to the uniform zoom parameter that calculates in the zooming engine of each source images correspondence, according to zooming parameter source images is zoomed to correspondence position in the target background by zooming engine, be combined into piece image by the source images of image sets compound module after then and export in the background terminal and show, realize presenting of combination image thus uniform zoom.
The image that the application said structure is finished in the embodiment of the invention is current, because can uniform zoom parameter and the optimized placement position of corresponding acquisition source images in target background according to the parameter of source images and target background, therefore need not picture is cut or is out of shape, guaranteed that the source images of different proportion can maximize and utilize without distortion the target background space to make up demonstration.
