Description
Technical field
The present invention relates to video processing technique, especially a kind of many pictures technique for displaying.
Background technology
A plurality of picture splicings are in the technology of a screen displayed, and promptly many pictures Display Technique all has application in a lot of fields such as video conference, guard monitor.As shown in Figure 1, in many pictures, each zonule picture displayed is called sprite, and whole viewing area is called many pictures, and each zonule is called the sprite zone.The size in sprite zone and quantity all are pre-determined, normally according to the quantity of the sprite that will show, wide and the height of many pictures is carried out five equilibrium cut apart, common have four pictures, nine pictures (horizontal triplex row, vertical three row), 16 pictures (horizontal four lines, vertical four row) etc.In the past; because picture the ratio of width to height of video source is consistent (being generally 4: 3) all; thereby many pictures show only to need each sprite is stitched together simply and get final product; but; present continuous development along with the HD video technology; HD video source (usually picture the ratio of width to height be 16: 9) is more and more, and this is presented at problem in many pictures with regard to sprite with different pictures the ratio of width to height how having occurred.In the prior art, two kinds of solutions are arranged:
First method is sprite to be carried out the cutting of level or vertical direction, and itself and multiple image ratio are consistent, and will carry out the equal proportion convergent-divergent to sprite then, puts into many pictures then, and its effect as shown in Figure 1.The shortcoming of this method is, by causing original image information to lose original image cutting, picture material is imperfect, and especially when being cut part and having useful information of image, this shortcoming is more outstanding.
Second workaround is that sprite occupy the sprite regional center and puts, and remainder is filled with black stripe.If the ratio of width to height of sprite is than the picture of manying the ratio of width to height hour, as the ratio of width to height is that to enter the ratio of width to height be many pictures of 16: 9 for 4: 3 sprite, be that benchmark carries out convergent-divergent during the sprite convergent-divergent then with the sprite region height, to fill out black stripe about sprite behind the convergent-divergent, sprite will be put into the corresponding sprite of many pictures zone between two parties; When if sprite the ratio of width to height is bigger than the picture of manying the ratio of width to height, the many pictures that enter 4: 3 as 16: 9 sprites, be that benchmark carries out convergent-divergent during the sprite convergent-divergent then with the sprite peak width, behind the convergent-divergent sprite is filled out black stripe up and down, sprite is placed in the middle, puts into the corresponding sprite of many pictures zone.Its effect as shown in Figure 2.The shortcoming of this method is to have the filling patterns such as secret note (promptly being positioned at the filling patterns such as secret note between sprite) of much cutting apart sprite in many pictures, and the sensation entire image is more scrappy, the influence sight.
As seen, prior art is when handling sprite with different the ratio of width to height and be presented in many pictures, if will guarantee that sub-screen image is not scrappy, then can sacrifice the integrality of sub-screen information, if will guarantee the integrality of sub-screen information, then can make picture scrappy, the influence sight.

Embodiment one
Fig. 4 is the flow chart of present embodiment.Present embodiment comprises the following steps:
S101, relatively the ratio of width to height R0 of sprite and the ratio of width to height R1 of many pictures; As R0＜R1, execution in step S102 then, as R0＞R1, execution in step S103 then, as R0=R1, execution in step S104 then;
S102, according to the resultant scaled sprite of the ratio of width to height of the ratio of width to height of described relatively sprite and many pictures, described sprite is that benchmark carries out convergent-divergent according to the height in corresponding sprite zone;
S103 is that benchmark carries out convergent-divergent according to the width in sprite zone;
S104 is that benchmark carries out convergent-divergent according to the height or the width in sprite zone.Convergent-divergent does not change the ratio of width to height of described sprite;
This sentences height or width is a benchmark, is to instigate the height of sprite or width consistent with the height or the width in corresponding sprite zone.For example, when the ratio of width to height is that 4: 3 sprite is when to enter the ratio of width to height be many pictures of 16: 9, the ratio of width to height of factor picture is less than the ratio of width to height of many pictures, so should be that benchmark carries out convergent-divergent, promptly guarantee that the height of sprite is consistent with the height in corresponding sprite zone during convergent-divergent with the height in corresponding sprite zone; When the ratio of width to height is that 16: 9 sprite is when to enter the ratio of width to height be many pictures of 4: 3, the ratio of width to height of factor picture is greater than the ratio of width to height of many pictures, so should be that benchmark carries out convergent-divergent, promptly guarantee that the width of sprite is consistent with the width in corresponding sprite zone during convergent-divergent with the width in corresponding sprite zone.
S105, sprite behind the placement convergent-divergent, with certain root line in many pictures or certain point serves as to place datum line or place datum mark, with certain point in the sprite is anchor point, and under the constraint of placing constraints, apart from the sprite of placing after datum line or the nearest rule of placement datum mark are placed described convergent-divergent, vacant part is inserted filling pattern according to anchor point;
Datum line can be any line in many pictures, and datum mark also can be any one point in many pictures, and anchor point then can be any one point in the sprite.Especially, can determine to place datum line according to the benchmark of convergent-divergent, as if being the benchmark convergent-divergent with the width, serve as to place datum line with a horizontal line in many pictures then, if highly to be the benchmark convergent-divergent, serves as to place datum line with a vertical line in many pictures then; Further, as if being the benchmark convergent-divergent, serve as to place datum line then with the horizontal center line in many pictures with the width, if highly to be the benchmark convergent-divergent, serve as to place datum line then with the vertical center line in many pictures.In addition, can choose many pictures central point for placing datum mark.Described placement constraints is that the distance between adjacent sprite edge is default distance, and not overlapping between sprite; Perhaps sprite is confined in the corresponding sprite zone.This default distance can be 0.Filling pattern then can be any pattern, for example stick of solid color, textured pattern etc.
