Abstract: A distance measurement device includes an imaging unit which captures a subject image formed by an 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 subject, a derivation unit which derives a distance to the subject based on the timing at which the directional light is emitted and the timing at which the reflected light is received, a display unit which displays the subject image, and a control unit which performs control such that, in a case of performing a distance measurement, the display unit displays the subject image as a motion image and transition is made to a state where actual exposure by the imaging unit is possible at the timing of the end of the distance measurement.

Abstract: 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.

Abstract: A laser ranging unit is rotatably attached to a camera body by a hinge unit. The camera body has a first imaging unit and a laser radiation position specification unit. The laser ranging unit has a laser radiation unit, a laser receiving unit, a second imaging unit, and a distance calculation unit. The first imaging unit images a first range to generate a first image. The laser radiation unit is able to radiate a laser beam in an arbitrary direction within the first range. The laser receiving unit receives a reflected beam of the laser beam. The second imaging unit images a second range including a radiation position of the laser beam within the first range to generate a second image. The laser radiation position specification unit searches for a portion matching the second image in the first image to specify the radiation position in the first image. The distance calculation unit calculates the distance to the radiation position based on the time of receiving the reflected beam.
