Abstract
Provided is an action control device, including a variable-transmittance ND filter configured to have transmittance that varies according to an applied voltage, an applied voltage control unit configured to control a voltage to be applied to the variable-transmittance ND filter, and a diaphragm control unit configured to control illuminance through a diaphragm. At a time of monitoring, the illuminance is controlled such that the applied voltage control unit applies a substantially minimum voltage to the variable-transmittance ND filter, and the diaphragm control unit opens or closes the diaphragm, and at a time of imaging preparation or imaging, the illuminance is controlled such that the applied voltage control unit applies a certain applied voltage to the variable-transmittance ND filter in a state of the substantially minimum voltage, and controls transmittance, and the diaphragm control unit performs control such that the diaphragm enters a fully opened state or substantially fully opened state.
