Abstract
An image signal obtained by a CCD image sensor is amplified by an amplifier. A gain of the amplifier is changed according to an ISO sensitivity. An AE circuit measures light intensity of a subject. According to the measured light intensity, a correct exposure time of the CCD image sensor is calculated. The exposure time of the CCD image sensor is changed by a CCD driver. In the exposure adjustment, a system controller increases the gain by making the ISO sensitivity higher such that the calculated exposure time becomes shorter than a predetermined anti-camera shake exposure time.
