Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in more detail.
Referring to Fig. 3, be the indicative flowchart that picture segmentation of the present invention shows, it comprises the following steps:
The present invention carries out display screen picture while cutting apart, and no longer uniquely according to decile mode, carries out picture segmentation, as long as the unit rectangular configuration the ratio of width to height marking off is standard proportional.
Particularly, described picture segmentation mode can adopt the four angular coordinate formula of unit rectangular configuration to represent, four angular coordinate formula comprises screen resolution width variable and screen resolution height variable; Correspondingly, describedly according to picture segmentation mode, display screen is divided into a plurality of unit rectangular configuration and comprises: by the width of the screen resolution obtaining and height substitution four angular coordinate formula, obtain the four angular coordinate of each unit rectangular configuration.
Combination by number of pictures and the ratio of width to height is different, by the different picture segmentation mode of correspondence.Number of pictures take below as 4, and the ratio of width to height is respectively 4:3 and 16:9 is illustrated.
If number of pictures is 4, the ratio of width to height is 16:9, and the four angular coordinate formula of each unit rectangular configuration is following coordinate formula group (1):
Window 1:(0,0), (Y/3 * 4,0), (0, Y) and (Y/3 * 4, Y);
Window 2:(Y/3 * 4+1,0), (X, 0), (Y/3 * 4+1, Y/3) and (X, Y/3);
Window 3:(Y/3 * 4+1, Y/3+1), (X, Y/3+1), (Y/3 * 4+1, Y/3 * 2) and (X, Y/3 * 2);
Window 4:(Y/3 * 4+1, Y/3 * 2+1), (X, Y/3 * 2+1), (Y/3 * 4+1, Y) and (X, Y); Wherein, X is screen resolution width, and Y is screen resolution height.
Suppose that screen resolution is 1920:1080,1920/1080=16:9, for widescreen, if now adopting minute modes such as four pictures shown in Fig. 1 cuts apart, the Aspect Ratio of four windows that obtain is all 16:9, during due to collection, image data source coded system is 4:3, will make image be stretched, and causes anamorphose.To change partitioning scheme be shown in Fig. 4 in the present invention thus, by X=1920, coordinate formula group (1) above Y=1080 substitution, obtains the coordinate of four windows respectively:
Window 1:(0,0), (1440,0), (0,1080), (1440,1080);
Window 2:(1441,0), (1920,0), (1441,360), (1920,360);
Window 3:(1441,361), (1920,361), (1441,720), (1920,720);
Window 4:(1441,721), (1920,721), (1441,1080), (1920,1080).The four angular coordinate of each window is sequentially: lower left corner coordinate, lower right corner coordinate, upper left corner coordinate and upper right corner coordinate.
If number of pictures is 4, the ratio of width to height is 4:3, and the four angular coordinate formula of each unit rectangular configuration is following coordinate formula group (2):

Window 2:(X/2+1,0), (X, 0), (X/2+1, Y/2) and (X, Y/2);
Window 3:(0, Y/2+1), (X/2, Y/2+1), (0, Y) and (X/2, Y);
Window 4:(X/2+1, Y/2+1), (X, Y/2+1), (X/2+1, Y) and (X, Y); Wherein, X is screen resolution width, and Y is screen resolution height.
Particularly, suppose that screen resolution is 1024:768,1024/768=4:3, for standard screen, now can adopt minute modes such as four pictures shown in Fig. 1, by X=1024, coordinate formula group (2) above Y=768 substitution, the four angular coordinate that obtains each unit rectangular configuration is respectively:
Window 1:(0,0), (512,0), (0,384) and (512,384);
Window 2:(513,0), (1024,0), (512,384) and (1024,384);
Window 3:(0,385), (512,385), (0,768) and (512,768);
Window 4:(513,385), (1024,385), (513,768) and (1024,768).The four angular coordinate of each window is sequentially: lower left corner coordinate, lower right corner coordinate, upper left corner coordinate and upper right corner coordinate.
The number of pictures of take above illustrates as 4.If number of pictures is other values, can similarly divide.For example, for the widescreen of 16:9, if number of pictures is 16, the window in Fig. 41 can be divided into 4 wickets, by the window on the right 2,3 and 4 each be divided into four wickets, as shown in Figure 5,16 windows that obtain are all the standard proportional of 4:3; Each window coordinates in Fig. 5 can carry out after simple conversion is calculated obtaining by each formula in coordinate formula group (1).
While carrying out data source demonstration, if data source resolution is not identical with unit rectangular configuration resolution, need to carry out convergent-divergent to data source, particularly: by the proportionate relationship of data source resolution and unit rectangular configuration resolution, data source is carried out to convergent-divergent, in the data after convergent-divergent are presented at and identify corresponding unit rectangular configuration with unit rectangle on display screen.Resolution, the precision of screen picture namely, refers to the number of the pixel that display can show.Here, data source is scaled to the size of unit rectangular configuration resolution, then shows.
