METHOD FOR GENERATING SYNTHESIS KEY FRAME AND VIDEO BROWSING SYSTEM UTILIZING IT

摘要

PROBLEM TO BE SOLVED: To provide a method for generating a synthesis key frame that can express a large amount of information on a screen with a specified size. SOLUTION: The method of this invention includes a step where an input of a video stream outputted from a source is received and the video stream is divided into blocks having significance, a step where a key frame/key frame or a key area/key area representing the divided blocks is selected, and a step where the selected key frame/key frame or key area/key area are combined to synthesize them to one frame. By sequentially performing the above steps, a synthesis key frame is generated.
