In a device for controlling an imaging device, a voltage fSUB which is applied to a substrate of a CCD is changed in accordance with an exposure compensation value. Switches are turned ON or OFF in accordance with the exposure compensation value, and an MPU 15 accordingly controls a substrate voltage control circuit. When the exposure compensation value has a positive value, the substrate voltage fSUB is set to a high value, so that the saturation level of the CCD becomes low; thus, an overflown surplus electric charge caused by a large amount of incident light is easily absorbed by a depletion layer of the CCD. When the exposure compensation value has a negative value, the substrate voltage fSUB is set to a low value. As a result, the saturation level of the CCD becomes high, and thus the dynamic range for sensing image luminances of varying levels is increased.
