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.
