Description

Image presenting method and device

The present application claims priority to Chinese Patent Application No. 200810098123.8, entitled "An Image Presentation Method and Apparatus", filed on May 13, 2008, the entire disclosure of which is incorporated herein by reference. .

Technical field

The present invention relates to the field of image communication technologies, and in particular, to an image presentation method and apparatus.

Background technique

The current conference television provides the function of combining pictures, and the combined picture refers to displaying at least one sub-picture in a background terminal, the sources of these sub-pictures being video images of different aspect ratios. The combined picture includes two modes: PIP (Picture in Picture) and POP (Picture Out Picture). The PIP mode usually includes two sub-pictures, one of which is displayed in the background terminal and the other The sub-picture is displayed in the form of a small picture in one of the upper left corner, the lower left corner, the upper right corner, and the lower right corner of the background terminal; the POP mode displays at least one sub-picture in one background terminal, and the sub-pictures do not overlap. For the POP mode, since the ratio of the width and height of the source video images corresponding to the respective sub-pictures is different, the combined display of the sub-pictures on the background terminal is complicated. In the prior art, the method of scaling the sub-pictures is usually adopted, or The way of cutting the deformation adapts each sub-picture to the background terminal.

When the sub-picture is displayed on the background terminal by using the proportional scaling method, the background space is divided into sub-background spaces corresponding to the number of sub-pictures according to the split-screen mode of the sub-picture, and then the source video images corresponding to the respective sub-pictures are adapted to Corresponding in the sub-background space. When the source video image of a sub-picture has a different aspect ratio corresponding to the allocated sub-background space, it is necessary to fill the background color or the background pattern in the extra sub-background space. Therefore, the background space cannot be fully utilized by the proportional scaling method, and the visual effect of viewing the background terminal is affected by the color or pattern filled in the excess background space around the video image.

When the sub-picture is displayed on the background terminal by using the cutting deformation mode, the background space is first divided into sub-background spaces corresponding to the number of sub-pictures according to the frequency division mode of the sub-picture, and then the source video image corresponding to each sub-picture is cut and deformed. Processing, so that the aspect ratio of the processed video image is consistent with the aspect ratio of the background space corresponding to the video image, and then scaling the video image to the corresponding background space for display. Therefore, the use of cutting deformation is easy to lose and deform the video image, thereby The processed video image is made inconsistent with the source video image, resulting in distortion of the video image displayed in the background terminal.

Summary of the invention

An object of the embodiments of the present invention is to provide an image presenting method and apparatus, so that each sub-picture displayed on a target background can fully utilize the background space, avoiding the use of the equal-scale zooming method, thereby making full use of the background space, and adopting the cutting deformation. The video image is distorted by the way.

(SubHl+SubH4=SubH2+SubH3). Since the aspect ratio of the image formed by the scaled image 1, image 2, image 3, and image 4 is larger than the aspect ratio of the target background, the relationship between the source image parameter and the target background parameter obtained is equal. The width of the scaled source image 1 and the source image 2 (that is, the sum of the widths of the scaled source image 3 and the source image 4) is equal to the width of the target background (SubWl+SubW2=BackW and SubW3+SubW4=BackW) » According to the calculated SubWl, SubHl, SubW2, SubH2, SubW3, SubH3, SubW4, SubH4, the source image 1, the source image 2, the source image 3, the source image 4, etc. are scaled to the target background, as shown in FIG. 9B. .
