Abstract

The invention discloses an image presenting method which comprises the following steps: receiving a source image parameter and a target background parameter used for presenting a source image, and according to the source image parameter and the target background parameter, calculating a geometric scaling parameter and a corresponding position in a target background of the source image; scaling the source image according to the geometric scaling parameter; and according to the corresponding position of the source image in the target background, combining the scaled source image into an image and outputting the combined image. The invention also discloses an image presenting device. When the invention is used for presenting the image, because the geometric scaling parameter and an optimal layout position of the source image in the target background can be correspondingly obtained according to the parameters of the source image and the target background, a picture does not need to be cut or deformed so as to ensure that the image cannot be distorted and guarantee that the source images of different proportions can be maximally combined and displayed by utilizing a target background space without distortion.

Description

technical field [0001] The present invention relates to the technical field of image communication, in particular to an image presentation method and device. Background technique [0002] The current conference TV provides the function of combining pictures. Combining pictures refers to displaying at least one sub-picture in a background terminal, and the sources of these sub-pictures are video images with different aspect ratios. Combined screen includes PIP (Picture in Picture, picture in picture) and POP (Picture outPicture, split screen) two modes, PIP mode usually includes two sub-pictures, one of which is maximized and displayed in the background terminal, while the other sub-picture The picture is displayed in one of the upper left corner, lower left corner, upper right corner, and lower right corner of the background terminal in the form of a small picture; in POP mode, at least one sub-picture is displayed in a background terminal, and the sub-pictures do not overla...
