Abstract
A range imaging system includes: a control unit that generates a light emission signal for instructing light irradiation and an exposure signal for instructing exposure; a pulsed-light source unit that emits pulsed light in response to the light emission signal; an imaging unit that includes a solid-state imaging device and performs exposure and imaging in response to the exposure signal; and a calculation unit that calculates range information. The solid-state imaging device includes a first pixel for receiving radiant light from a subject and a second pixel for receiving reflected light of the pulsed light. The calculation unit calculates the range information using an image capture signal from the first pixel and an imaging signal from the second pixel.
