Abstract:
1. A color signal processing circuit for performing white balance adjustment of color signals by obtaining said color signals and an infrared signal that are output from a color image capture element and controlling the gain of at least two signals among said color signals on the basis of said infrared signal, wherein the color image capture element comprises: a plurality of color components photoelectric conversion elements, each disposed with a color filter on a light receiving surface for respectively transmitting different color components, for receiving incoming light and selectively outputting respective color signals corresponding to the intensity of said different color components; and an infrared component photoelectric conversion element, disposed with an infrared component transmitting filter on a light receiving surface for transmitting an infrared component, for selectively outputting the infrared signal used to correct the infrared component included in at least one of the color signals.
