PROBLEM TO BE SOLVED: To provide a programmable color balance which ensures efficient use of a silicon area and high signal-to-noise ratio(SN ratio). SOLUTION: A pixel architecture 20 has a transfer gate bus for each color. For example, a TGg bus 1 is connected to transfer gates 24 of green pixels in a column A, and a TGr bus 2 is connected to transfer gates 24 of red pixels in the column A. Since the bus is provided for each color, the time for which charges are stored in a PD 22 can be determined color by color. Since the color balance is obtained by such a method that depends on the charges to be stored in the PD 22, noise in the circuit can be reduced.
