Problems solved by technology

However, for videos that already have black borders, the method of cutting black borders requires a lot of work and the operation process is complicated. Since special software tools are required to process video files, the operation difficulty and cost are increased; and this method can only Remove the black borders of the original video, but cannot remove the black borders of the playback screen
Although the method of manually adjusting the zoom ratio of the screen can remove the black borders of the playback screen, it is not accurate enough due to the need for manual fine-tuning; the operation process is cumbersome due to the inability to intelligently adjust the black border area, and the user needs to control the zooming process of the video

Embodiment Construction

[0033] Such as image 3 As shown, a method for displaying a video image comprises the following steps:

[0034] In step S10, the black border area in the video display interface is identified. A video is composed of a video sequence, and each frame in the video sequence is an image. For a video that only includes a valid frame area (ie, a video without black borders), the valid frame area is all content in each frame. For a video that does not only contain an effective picture area (that is, there is a black border), it is necessary to identify the black border area in the video display interface to obtain the size of the effective picture area (usually expressing its length and height in pixels).

[0035] In one embodiment, the specific process of step S10 is: select at least two frames of images in the video sequence, perform pixel scanning on the at least two frames of images, and identify the area with the same pixel in each frame as the black border in the video display...

Abstract

The invention relates to a video picture displaying method. The method comprises the following steps of: identifying a black edge area in a video display interface; scaling an original effective picture area according to the identified black edge area; and displaying a scaled effective picture area in the video display interface. In addition, the invention further provides a video picture displaying device. With the adoption of the method and the device, a display area of a video picture can be self-adaptively adjusted so as to meet various needs of users.

Description

【Technical field】 [0001] The present invention relates to the technical field of video processing, in particular to a method and device for displaying video images. 【Background technique】 [0002] At present, many videos have black borders when they are played. Such as figure 1 As shown, there are some black borders around the video area; for example figure 2 As shown, some black bars appear on the top and bottom of the video. The so-called black border refers to the image displayed on the video display interface except for the effective image area, and there is a fixed area of ​​black or other colors around the effective image area. Removing this fixed area will not affect the viewing of the video. Such as figure 1 As shown, 1 is the effective image area, which can provide effective video information, and removing this area will result in incomplete video images; 2 is the black border. [0003] Black borders include original video black borders and playback screen bla...
