Abstract
A distance measurement device includes an imaging unit, an emission unit, a light receiving unit, a derivation unit which derives a distance to the subject based on a timing at which directional light is emitted and a timing at which reflected light is received, an execution unit which executes at least one of focus adjustment of an imaging optical system with respect to the subject or exposure adjustment prior to imaging by the imaging unit, and a control unit which performs control such that the timing at which at least one of focus adjustment or exposure adjustment is executed by the execution unit and the timing of a distance measurement by the emission unit, the light receiving unit, and the derivation unit are synchronized and performs control such that transition is performed to a state where actual exposure by the imaging unit is possible after the distance measurement is completed.
