Distance measuring device and sensor device

Abstract

A distance measuring device includes: a pixel array unit that performs a light receiving operation for time-of-flight distance measurement using a modulation frequency; a distance measurement processing unit that performs dual mode distance measurement that causes the pixel array unit to alternately perform a light receiving operation using a first frequency as the modulation frequency and a row receiving operation using a second frequency having a higher frequency than the first frequency as the modulation frequency, and single mode distance measurement that causes the pixel array unit to perform only a light receiving operation using a predetermined frequency as the modulation frequency; and a switching processing unit that switches the distance measurement in the dual mode and the distance measurement in the single mode according to a predetermined condition.
