Abstract
An imaging device includes: an imaging element; a neutral density (ND) filter unit including a plurality of filter holders, each of the filter holders being mounted with a plurality of optical ND filters having different transmittances and being able to selectively insert the optical ND filters into an incident optical path for the imaging element; and a control unit. The control unit can variably set the transmittance of the ND filter unit by performing drive control of switching the optical ND filter to be inserted into the incident optical path for each of the plurality of filter holders, and in a case where driving of the plurality of filter bodies is required for switching to a target transmittance, performs control such that the plurality of filter holders to be driven is simultaneously displaced in a direction and a displacement amount equal to each other.
