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 shake correction control device includes an acquisition unit and an operation control unit. The acquisition unit acquires, for each predetermined time, a related amount related to an operation recommendation condition under which an operation of a mechanical correction unit which corrects a shake of a subject image by mechanically moving at least one of a correction optical system or an imaging element is recommended. The operation control unit controls the operation of the mechanical correction unit and an operation of an electronic correction unit which corrects the shake by performing image processing on an image obtained by imaging performed by the imaging element. In a case where a state where the related amount acquired in the acquisition unit satisfies the operation recommendation condition does not continue for a setting period defined by a time series of a plurality of consecutive times, the operation control unit performs a control for operating only the electronic correction unit out of the mechanical correction unit and the electronic correction unit.

Abstract: A shake correction control device includes an acquisition unit and an operation control unit. The acquisition unit acquires, for each predetermined time, a related amount related to each of a first operation recommendation condition under which an operation of a mechanical correction unit that corrects a shake of a subject image by mechanically moving at least one of a correction optical system or an imaging element is recommended, and a second operation recommendation condition under which an operation of an electronic correction unit that corrects the shake by performing image processing on an image obtained by imaging performed by the imaging element is recommended. The operation control unit performs a control for selectively operating the mechanical correction unit and the electronic correction unit at a subsequent time of a plurality of consecutive times depending on the first operation recommendation condition, the second operation recommendation condition, and a plurality of related amounts that are the related amounts acquired by the acquisition unit and correspond to the plurality of consecutive times.

Abstract: A system control unit consecutively images a subject by driving based on a global shutter method, divides captured image data obtained by the imaging into a plurality of areas, and each time each area is generated, compares the generated area with the same area as the area in the captured image data generated by the imaging performed before the imaging, and detects a moving object from the area based on a result of the comparison. Based on a change in position of the detected moving object, the system control unit predicts a timing at which a trigger range TR set in the captured image overlaps with the moving object, and performs automatic imaging in a frame period that includes the timing.

Abstract: An imaging control device includes: an imaging controller that obtains captured image data by controlling an imager imaging a subject through an optical element having variable transmittance of light; a flicker detector that detects a flicker occurring in the captured image data based on the captured image data; and a transmittance controller that controls, based on the flicker, the transmittance of the optical element to a state where a quantity of light incident on the imager is changed in a cycle shorter than a cycle of the flicker, and the imaging controller controls an exposure time of the imager to a natural multiple of a changing cycle of the quantity of light incident on the imager in a condition where the transmittance of the optical element is controlled to the state.
