Abstract: An imaging apparatus is equipped with an analog block, an imaging condition determination section, and an analog gain control section. Current consumption of the analog block changes in accordance with an analog gain, which is an amplification ratio of outputs of an imaging device. The imaging condition determination section determines imaging conditions, including the analog gain, in accordance with the brightness of an imaging object. Depending on a state of the imaging apparatus, the analog gain control section alters the analog gain determined by the imaging condition determination section so as to reduce the current consumption of the analog block. Thus, in this imaging apparatus, the current consumption of the analog block may be reduced by the performance of control that alters the analog gain in accordance with the state of the imaging apparatus. Thus, the state of the imaging apparatus may be regulated.
