Abstract

The invention aims to provide a method for realizing enhancement processing for subtitle texts in video images and a device. The subtitle enhancement device identifies a subtitle text in a subtitle area according to the subtitle area in a video image when preset subtitle enhancement triggering conditions are met, and the subtitle text is in enhancement processing, so that the subtitle text is clearly displayed in the video image. Compared with the prior art, the method for realizing enhancement processing for subtitle texts in video images and the subtitle enhancement device have the advantages that the subtitle text in the video image can be clearly displayed by means of enhancement processing for the subtitle text contained in the video image, better playing experiences are realized for users when a video is played, the subtitle enhancement device does not always work by means of setting the triggering conditions for enhancement processing for the subtitle text, or subtitle enhancement processing for an integral video file can be omitted, and accordingly load pressure and/or computation load of equipment with the subtitle enhancement device are reduced.

Description

technical field [0001] The invention relates to the technical field of video playing, in particular to a technology for enhancing subtitle text in video images. Background technique [0002] In the existing video files, there are mainly two types of subtitles: one kind of subtitles is used as additional information, independent of video data, and only when the video file is played, the subtitles are superimposed on the video image according to the time axis; the other type of subtitles is used as Part of the video data, encoded with the video content to generate a video image, which is embedded in the video image when the video file is played. [0003] However, for subtitles embedded in video images, due to reasons such as video bit rate and resolution, these subtitles are used as video auxiliary information, and often have poor definition, which seriously affects the user's video playback experience. [0004] Therefore, how to enhance the subtitle text in the video image s...
