PROBLEM TO BE SOLVED: To provide a technique which does not increase random noise for noise suppression using a black image. SOLUTION: A noise suppressor according to the present invention includes an input section, a black image processing section, and a noise suppression section. The input section inputs image data obtained by imaging a field by an imaging section and a plurality of black image data obtained by imaging the field by the imaging section in a light shield state. The black image processing section generates black image data B by suppressing noncorrelative random noise between the plurality of dark image data. The noise suppression section suppresses noise of the image data based upon black image data B. COPYRIGHT: (C)2007,JPO&INPIT |
