Embodiment Construction

[0015] A system and method for superimposing image subtitles of the present invention will be further described in detail below with reference to the accompanying drawings.

[0016] Such as figure 1 As shown, the system for overlaying image subtitles includes a control module 1 , a subtitle adding module 2 , an image subtitle mixing module 3 , and a subsampling module 4 . The control module 1 is connected to the image subtitle mixing module 3 and the down-sampling module 4 respectively, and the image subtitle mixing module 3 is connected to the subtitle bordering module 2 and the down-sampling module 4 respectively. The subtitle signal is input from the image subtitle mixing module 3 through the subtitle adding module 2 , the image signal is also input from the image subtitle mixing module 3 , and the mixed image and subtitle signal are output through the downsampling module 4 .

[0017] refer to figure 2 and image 3 , specifically explain the working process of the image...

Abstract

The invention relates to a system and method for superimposing subtitles on dynamic or static images. The existing method has the defects on pollution of each other's color images and subtitles through the way of superimposing subtitles on the video content directly. The system includes a control module, a hybrid module and an image sampling module, which are connected with each other. The image-signals are input at one end of the hybrid module. The subtitle-signals are input at the other end of the hybrid module by the subtitles bordering module involved in the described system. Then the mixed signals of images and subtitles are output through the image sampling module.

Description

technical field [0001] The invention relates to a subtitle superimposing system and method, in particular to a system and method capable of superimposing subtitles on dynamic or static images. Background technique [0002] Since Hong Kong, Taiwan and foreign film and television works entered the Chinese mainland market, subtitles have become an indispensable part of these works. Since most foreign works are original soundtracks, ordinary viewers must rely on subtitles to understand the content of the film. Therefore, for a good work, the clarity of subtitles is very important. Subtitles that are too dark, too small, and blended with the background image will cause visual fatigue to the audience. Often, before a movie is finished, they need to pause and rest, or even lose interest in continuing to watch the movie. [0003] At present, the method of superimposing subtitles on image or video content mainly uses the On-Screen Display (OSD) technology, that is, when playing vide...
