Abstract
A distance measurement device includes an imaging unit which captures a subject image formed by an imaging optical system forming the subject image indicating a subject, an emission unit which emits directional light as light having directivity along an optical axis direction of the imaging optical system, a light receiving unit which receives reflected light of directional light from the subject, a derivation unit which derives a distance to the subject based on a timing at which directional light is emitted by the emission unit and a timing at which reflected light is received by the light receiving unit, and a control unit which performs control such that at least a part of an imaging period by the imaging unit overlaps at least a part of a distance measurement period by the emission unit, the light receiving unit, and the derivation unit.
