摘要
The present invention generally relates to a multimedia browsing system, and more particularly, to a method for generating a synthetic key frame, which allows a video stream to be efficiently summarized while being searched and filtered based upon the summarization. The present invention generates the synthetic key frame based upon video text by calculating an importance measure of text areas extracted from the video image and using only those text areas having the importance measures of at least a predetermined value.
