Abstract
An image pickup device receives an incident light by way of the color filter that also transmits an infrared light component. For the purpose of correcting an infrared light component contained in an output signal, a control unit adds correcting infrared light components to image signals of multiple colors supplied from the image pickup device, respectively. To remove the infrared light components contained in the output signals, the correcting infrared light components are subtracted from the image signals of multiple colors supplied from the image pickup device. The control unit switches between an addition processing where an infrared light component is added and a subtraction processing where the infrared component is subtracted, according to a predetermined condition.
