Abstract
According to the first aspect of the present technology, there is provided an action control device, including a transmittance specifying unit configured to specify a transmittance of a variable-transmittance neutral density (ND) filter having a transmittance that varies according to an applied voltage, and an applied voltage control unit configured to control a voltage to be applied to the variable-transmittance ND filter such that the transmittance specified by the transmittance specifying unit is obtained. The applied voltage control unit controls the voltage to be applied to the variable-transmittance ND filter such that the transmittance of the variable-transmittance ND filter specified by the transmittance specifying unit is maintained at a timing at which an imaging preparation instruction or an imaging instruction is given.
