Abstract
In a distance measuring device that measures a distance to an object using a round-trip time of light, a solid-state image sensor includes a plurality of pixel groups capable of being exposed independently, and causes each of the plurality of pixel groups to receive, at a different exposure time, reflected light from the object that is originally pulsed radiation light from a light emitter. A light emission and exposure controller cyclically and intermittently exposes each of the plurality of pixel groups of the solid-state image sensor at the different exposure time to obtain pixel signals of types corresponding to a time difference between the reflected light and the radiation light, and a signal processor obtains information about the distance to the object according to pixel signals of adjacent pixels exposed at different exposure times for each of the plurality of pixel groups.
