Method for painting subtitle by using pixel as unit

Abstract

The invention relates to a method for painting a subtitle by using pixel as unit. An external subtitle file is read and a subtitle is painted by using the pixel as the unit. The method comprises the following steps: firstly, displaying a target row subtitle which corresponds to a target row serial number according to the target row serial number of the subtitle file and displaying a preparation row subtitle corresponding to a preparation row serial number before the subtitle file is terminated; secondly, reading a coordinate parameter and a time parameter which correspond to the target row subtitle, wherein the coordinate parameter includes a row coordinate figure and a line coordinate figure; if the line coordinate figure and the row coordinate figure are not terminated, a pixel which corresponds to the coordinate parameter is painted and 1 is added to the line coordinate figure. Therefore, the invention can improve the elasticity of the subtitle painting and save the storage space.

Description

technical field [0001] The invention relates to a subtitle coloring method, in particular to a subtitle coloring method with pixel as a unit. Background technique [0002] The text in the video can help us understand the information conveyed by the video. Therefore, the timing of matching the subtitles with the video is even more important. For example, "Karaoke" used in leisure and entertainment is a special way of expressing subtitles: it mainly cooperates with karaoke videos and displays subtitles on the videos. Subtitle coloring is a process of gradually changing from one color to another in line with the rhythm of the music. In the process of coloring, use the principle of superposition of layers: that is, subtitles before singing (subtitles before coloring) and subtitles after singing (subtitles after coloring) are different layers. For the subtitles after coloring, according to the start time and end time of subtitle coloring, the subtitles after coloring are superi...

AI Technical Summary

Problems solved by technology

[0003] 1. You need to know the content of the subtitle file you want to color, and you need to create the subtitle after coloring first, so there is no flexible coloring;

[0004] 2. Since karaoke lyrics often have dozens of sentences, there are also dozens of corresponding subtitles after coloring, so a large amount of hard disk storage space is occupied; and

[0005] 3. In the process of subtitle coloring, since dozens of layers are processed, not only a large amount of memory space is required, but it may also cause out-of-sync phenomenon due to speed delay during the subtitle coloring process
