An image pickup apparatus includes an image sensor that reads out an image in a time period Te, a mechanical shutter that opens and closes in a traveling time Tm that satisfies Te>Tm, a system control section that controls the mechanical shutter to set a time period from opening to closing of the mechanical shutter to T1 and causes the image sensor to continuously read out images of a plurality of frames in a time period T2 that satisfies T1>T2, and an image combining section that generates a combined image from the images of the plurality of frames. The system control section performs control to fully read out electric charges exposed in any pixel in the time period T1.
