PROBLEM TO BE SOLVED: To provide an inexpensive color camera with a smaller hardware configuration compared with a prior art hardware configuration by solving such a problem that a cyclic noise reduction circuit in a single panel color camera requires a frame memory, which makes a hardware configuration a large scale, and requires a brightness signal noise reduction circuit, a color difference signal noise reduction circuit, and two noise reduction circuits, which make a circuit scale larger and more expensive. SOLUTION: The color camera obtains noise reduction processing only by processing of a single system by performing the noise reduction processing at an RAW signal stage before a color separation, so that a circuit configuration is reduced to 1/2. Further, by performing high brightness correction processing before the noise reduction processing, a color balance deviation in a moving subject is solved. COPYRIGHT: (C)2010,JPO&INPIT |
