To satisfactorily shield light to an imaging device by a mechanical shutter, while maintaining degrees of freedom in of frame period and shutter speed.
First and second shutter members 31, 32 are disposed in an optical path of an image beam incident through a lens, and each of the first and second shutter members 31, 32 can set a state, where incident light to the image pickup device is shielded, and a state, where incident light to the image pickup device is not shielded. At a shutter control section for controlling the first and second shutter members 31 and 32, the timing for shielding the light path by the first shutter member, and the timing for shielding the light path by the second timing are set based on the set imaging timing, thus variably setting the frame rate, where the imaging device captures images, and the exposure time in the imaging apparatus.
