Abstract
An image-capturing device includes an infrared light source configured to emit infrared light, and a solid-state image-capturing device including a plurality of first pixels configured to convert visible light into signal charge and a plurality of second pixels configured to convert infrared light into signal charge, the plurality of first pixels and the plurality of second pixels being arranged on a semiconductor substrate in a matrix. The solid-state image-capturing device outputs, during the same single frame scanning period, a first signal obtained from the plurality of first pixels, a second signal obtained from the plurality of second pixels during a period of time when the infrared light is emitted, and a third signal obtained from the plurality of second pixels during a period of time when the infrared light is not emitted.
