Abstract:
An image pickup apparatus comprising:image pickup means in which color filters of a predetermined set of a plurality of colors are arranged on a plurality of photo sensitive elements to obtain color signals of said predetermined set of colors, wherein said predetermined set of a plurality of colors includes complementary colors;complementary color-to-primary color converting matrix means for converting color signals including color signals of the complementary colors, obtained from said image pickup means into R, G, and B signals with a predetermined matrix operation using complementary color-to-primary color conversion matrix coefficients which are different from white balance adjusting coefficients, wherein said complementary color-to-primary color conversion matrix coefficients can be variably set;calculation means for calculating said complementary color-to-primary color conversion matrix coefficients from an output signal obtained by driving said image pickup means; andcomplementary color-to-primary color conversion matrix coefficients setting means for setting said complementary color-to-primary color conversion matrix coefficients calculated by said calculation means to said complementary color-to-primary color converting matrix means.
