Abstract:
A color image capture element comprises a plurality of color component 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 the different color components, and an infrared component photoelectric conversion element, disposed with an infrared transmitting filter on a light receiving surface for transmitting an infrared component, for selectively outputting an infrared signal. This enables the infrared component included in at least one of a plurality of color signals to be corrected, thereby improving the sensitivity of a color image capture apparatus.
