PURPOSE:To obtain a picture of high picture quality by performing fine control in accordance with the extent of motion in the case of the motion to satisfactorily prevent the degradation of the resolution. CONSTITUTION:A motion detecting circuit 31 is provided to use different detection pulses to detect the state of motion stepwise at a high speed, a middle speed, and a low speed, and an electronic shutter driving circuit 30 controls in a manner that the electric charge storage time of a CCD 20 is shortened in accordance with the extent of the motion. Thus, the resolution is improved in the case of motion. In this case, the voltage of a light source power supply part 13 is increased/reduced in accordance with the extent of motion to improve the degradation of S/N due to a lack of the quantity of light (electric charge) so as to increase/decrease the voltage of a light source part 13.
