Abstract

The invention relates to a caption processing method and apparatus. The method includes the following steps: determining a caption-associated pixel set which includes pixels which are arranged in the region where the captions are; determining the color difference value between a designated color and the caption-associated pixel set, wherein the color difference value is intended for representing the differences between the designated color and the colors of the pixels in the caption-associated pixel set; based on the color difference value, determining the color to be used by the caption. By designating a color, based on the color difference value between the designated color and the caption-associated pixel set, the method selects the color of the caption. According to the invention, the method and the apparatus can ensure clear display of the caption and ensure the consistency of the color of the caption, prevents users from feeling uncomfortable due to frequency changes of captions, at the same time enables users to customerize the color of the caption, and improves user experience.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a subtitle processing method and device. Background technique [0002] Video subtitles can convey information to users more accurately, and it is even more important for subtitles in different dialects and foreign languages. At present, many players provide a subtitle color by default. When watching a video, the subtitle color is sometimes similar to the video content, causing users to be unable to see the subtitle content clearly. [0003] In the related art, a representative color of this region is obtained by counting the colors of all pixels in the video display area, and then the inverse color of this representative color is taken in a certain color space (such as HSV space) as the subtitle display color. In this way, a better contrast effect can be obtained, but the color of the subtitle may change frequently and the color of the subtitle is uncontrollable, w...
