Abstract
A time-of-flight distance measuring device divides a base exposure period into a plurality of sub exposure periods and holds without resetting an electric charge stored in the sub exposure period for a one round period which is one round of the plurality of sub exposure periods. The distance measurement value of short time exposure is acquired during the one round period and the distance measurement value of long time exposure is acquired during a plurality of the one round periods. Both of the distance measurement value of the long time exposure and the distance measurement value of the short time exposure can be acquired from the same pixel. With this, a dynamic range is expanded without being restricted by a receiving state of reflected light, optical design of received light, and an arrangement of pixels.
