<P>PROBLEM TO BE SOLVED: To provide a video signal processing unit capable of correcting a video signal on a white board into a clear video signal. <P>SOLUTION: The video signal processing unit includes an imaging device for imaging object video, and a video signal processor for signal processing the video signal obtained in the above imaging device. The image signal processor decides whether or not the object is the white board (S12), and modifies processing content according to the decision result in a white board decision section, so as to perform gamma correction processing (S14), scratch correction processing (S16) and edge enhancement and correction processing (S18). <P>COPYRIGHT: (C)2008,JPO&INPIT |
