Abstract: A method for eliminating subtitles of a video program is provided, where each of the subtitles is originally stored as a portion of an image of the video program. The method includes: detecting whether a sub-region of a specific color exists within a predetermined region on the image, in order to determine whether a subtitle exists; and when it is detected that the subtitle exists, changing at least one color within the predetermined region to eliminate the subtitle. An associated video display system is also provided.
