Abstract:
An image pickup device includes: a focal plane shutter including: a board including an opening; a shutter moving to open and close the opening; an actuator moving the shutter; and a detection portion detecting that the shutter passes through a predetermined position, an image pickup element which light enters through the opening; and a drive control portion that controls the actuator to move the shutter, wherein the drive control portion performs movement control to move the shutter at least until the shutter passes through the predetermined position, and performs brake control to decelerate the shutter while the shutter is moving after the shutter passes through the predetermined position.
