ABSTRACT:
An image pickup system includes photodiodes with color filters. A first color filter group includes visual light color filters, and a second color filter group includes a long red color filter at 640 nm or longer or a color filter at 580 nm and one of the visual light color filters. An infrared cut filter covers all the filters. A control circuit includes a fluorescent lamp distinguishing circuit for distinguishing a fluorescent lamp from other illuminating light sources by a ratio of an output signal from the photodiode with the long red filter to an output signal from the photodiodes with the visual light color filters; and a white balance control circuit for adjusting a white balance so as to match the illuminating light source distinguished by the fluorescent lamp distinguishing circuit.
