<p><P>PROBLEM TO BE SOLVED: To provide a video signal processor, a video signal processing method and a video signal processing program for photographing an image of high quality corresponding to a subject. <P>SOLUTION: In the video signal processor, a video signal obtained through photography by a CCD 102 is transferred to a buffer 105 through an A/D 104, and the video signal in the buffer 105 is transferred to a photometric evaluation part 106, a distance information calculation part 108, and a signal processing part 110. The distance information calculation part 108 calculates information on the distance from an imaging apparatus to the subject, and transfers it to a lens control part 107 and a correction coefficient calculation part 112. The correction coefficient calculation part 112 calculates a correction coefficient based upon the information on the distance between the imaging apparatus and the subject obtained through the distance information calculation part 108. A conversion part 111 sets a gray-level conversion curve using a histogram of a local area and the correction coefficient calculated by the correction coefficient calculation part 112, and applies gray-level conversion processing to the video signal. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
