Abstract:
1. An imaging apparatus comprising: an imaging unit including an image sensor configured to photoelectrically convert an object image to accumulate electric charge; a diaphragm control unit configured to control an aperture value of a diaphragm configured to adjust an amount of light incident on the image sensor; and an adjustment unit adjust a length of a charge accumulation period of the image sensor by adjusting a driving timing of the image sensor, wherein, if driving of the diaphragm overlaps a charge accumulation period when the aperture value is changed from a first aperture value to a second aperture value, the adjustment unit adjusts the length of the charge accumulation period that driving of the diaphragm overlaps, such that an amount of exposure of the imaging unit of the charge accumulation period that a first aperture value is set and an amount of exposure of the imaging unit of the charge accumulation period that the driving of the diaphragm overlaps become approximately equal to each other.
