PROBLEM TO BE SOLVED: To calculate a WB gain value through RGB three-plate plane processing and to adjust white balance of the RGB three-plate plane processing and white balance of Bayer processing using the WB gain value.SOLUTION: An A/D conversion section 102 converts the output of an imaging device 101 into a digital signal, and a G pixel oblique addition section 103 adds Gr and Gb together. A WB gain calculation section 106 calculates a gain for adjusting white balance with signals of R, G, and B three plate planes of the output of the G pixel oblique addition section 103. An AWB processing section 105 adjusts white balance of the R, G, and B three plate planes, and an AWB processing section 107 adjusts white balance of signals R, 2Gr, 2Gb, and B as the output of the G pixel oblique addition section 104. |
