In order to reduce the frame rate, when all photodiodes contributing to output of a video signal in a CMOS image sensor must be simultaneously exposed (at the timing of strobe flashing Deltats), as in a case where strobe is flashed, readout pixels composing the CMOS type image sensor are thinned such that the number of photodiodes contributing to the video signal outputted from the CMOS type image sensor is reduced. A time period Deltatp2 required for processing (of the video signal caused by a row of photodiodes) in an analog processing circuit connected to the succeeding stage of the CMOS type image sensor is shortened, thereby reducing the frame rate.
