Abstract
In a system that captures image data, a distance to an object is measured without adding a range sensor. A light emitting unit applies invisible light in synchronization with a predetermined light emission control signal. An invisible light pixel photoelectrically converts reflected light with respect to the invisible light to generate a pulse signal as an invisible light pulse signal. A visible light pixel photoelectrically converts visible light to generate a pulse signal as a visible light pulse signal. A counting unit performs processing for counting a number of the visible light pulse signals and perform processing for counting, in synchronization with the light emission control signal, a number of the invisible light pulse signals.
