There is provided an image pickup apparatus excellent in color reproducibility without requiring a complicated circuit. In image pickup operation, a sum pixel signal (SCCD) output from a color image pickup element (100) is converted into digital sum pixel data (DCCD) through a sample/hold circuit (102) and an A/D converter (104). The digital sum pixel data is stored and held in a frame memory (106). In image reproduction, an arithmetic operation unit (108) executes an arithmetic processing program in a program memory (110) to read out the sum pixel data (DCCD) from the frame memory (106). The pixel data are multiplied by predetermined white balance adjustment coefficients, and color difference signals (B-Y) and (R-Y) of the horizontal lines are calculated. In order to complement color difference signals of horizontal lines which are short, the color difference signals (B-Y) and (R-Y) are added and averaged in accordance with predetermined relations to form color difference signals of all horizontal lines, thereby realizing image reproduction excellent in color reproducibility.
