Abstract
An image sensor includes a plurality of pixels arranged in a matrix and has an electronic focal plane shutter function for providing a predetermined reset signal to the pixels on a pixel line to pixel line basis to perform an exposure start operation. A mechanical focal plane shutter is disposed immediately before the image sensor. A control unit causes the image sensor to perform the exposure start operation using the electronic focal plane shutter function a predetermined period of time after a curtain group of the mechanical focal plane shutter is open and causes the mechanical focal plane shutter to perform an exposure end operation when a shutter speed is set to low. The control unit causes the mechanical focal plane shutter to perform the exposure start operation and the exposure end operation when the shutter speed is set to high.
