IMAGING SYSTEM AND VIDEO SIGNAL PROCESSING PROGRAM

摘要

An imaging system subjects a video signal of an image captured by imaging means (lens system (100), diaphragm (101), CCD (102)) to gradation conversion considering the imaging condition. In the first embodiment, the imaging system includes an imaging condition judgment unit (108) for judging the imaging condition of the image, an information amount modification unit (107) for modifying the information amount of the video signal according to the imaging condition judged by the imaging condition judgment unit (108), and a gradation conversion unit (110) for performing gradation conversion in accordance with the gradation conversion characteristic obtained by using the video signal whose information amount has been modified by the information amount modification unit (107).
