Abstract
A camera device includes: an iris unit for varying exposure; a shutter control unit for varying a shutter speed of an imaging element; and a control unit for controlling the signal processing unit and the entire device. The camera device further includes: an exposure target calculation unit for calculating a control value used for controlling the iris unit or the shutter control unit so that an exposure amount will be a target value based on information on a signal level from a signal processing unit; and a malfunction judgment unit for determining a malfunction in the device based on information on the control value obtained by the exposure target calculation unit and the signal level from the signal processing unit.
