PROBLEM TO BE SOLVED: To provide an image pickup device capable of finding a white balance control value for exact white balance control. SOLUTION: A chrominance signal from an imaging device not shown in Figure is expanded on a chromaticity coordinate by white discrimination operation 102, it is decided by white decision 103 whether the expanded result is included in plural white discrimination areas of different color temperatures to be discriminated as white on the chromaticity coordinate or not, and each of white balance control values and each of evaluation indexes are found by the evaluated result in each of white discrimination areas. On the basis of the ratio of such evaluation indexes, the white balance control value for performing white balance control is found by the respective white balance control values and white balance control is performed.
