DISTANCE MEASUREMENT DEVICE, DISTANCE MEASUREMENT METHOD, AND DISTANCE MEASUREMENT PROGRAM

摘要

A distance measurement device includes an imaging optical system, an imaging unit, an emission unit, a derivation unit which performs a distance measurement to derive a distance to a 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 a light receiving unit, a shake correction unit which performs shake correction as correction of shake of the subject image caused by variation of an optical axis of the imaging optical system, and a control unit which performs control such that the shake correction unit does not perform shake correction or performs shake correction with a correction amount smaller than a normal correction amount determined in advance in a case of performing the distance measurement and performs shake correction with the normal correction amount in a case of not performing the distance measurement.

1. A distance measurement device comprising:
an imaging optical system which forms a subject image indicating a subject; an imaging unit which captures the subject image formed by the imaging optical system; 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 the directional light from the subj ect; a derivation unit which performs a distance measurement to derive a distance to the subject based on a timing at which the directional light is emitted by the emission unit and a timing at which the reflected light is received by the light receiving unit; a shake correction unit which performs shake correction as correction of shake of the subject image caused by variation of the optical axis of the imaging optical system; and a control unit which performs control such that the shake correction unit does not perform the shake correction, or performs the shake correction with a correction amount smaller than a normal correction amount determined in advance in a case of performing a distance measurement operation relating to the distance measurement and synchronously performing an imaging operation for a still image by the imaging unit, and performs the shake correction with the normal correction amount in a case of performing the imaging operation without performing the distance measurement operation.
