Abstract: A lens barrel includes a lens drive unit that moves a lens holder holding a lens in an optical axis direction, a locking mechanism that regulates movement of the lens holder at a movable end of the lens holder, and a control unit that performs, as a shift process for shifting the lens holder to a movement regulated state produced by the locking mechanism, control for moving the lens holder by using the lens drive unit to a position where movement regulation is achieved by the locking mechanism in a state where movement regulating force generated by the locking mechanism is reduced.

Abstract: To suppress a difference in brightness and darkness in a captured image caused by a difference in an exposure start time by a rolling shutter even if the exposure period is not changed. Provided is an imaging device including a gain setting unit configured to set a gain for each line in which a plurality of pixels is arrayed, the plurality of pixels being two-dimensionally arranged in a matrix in an image sensor, on the basis of diaphragm drive information regarding a diaphragm drive locus representing a time-series change in a diaphragm value. Thereby, the difference in brightness and darkness in a captured image caused by the difference in an exposure start time by a rolling shutter can be suppressed even if the exposure period is not changed.
