Abstract:
An imaging apparatus comprising:a photoelectric converter that converts accumulated light into electrical charges; a mechanical shutter that includes a light-shielding member that is movable in a first direction to selectively shade the photoelectric converter from light; and a controller that controls the photoelectric converter and the shutter, the controller controlling the photoelectric converter to perform: (a) charge accumulation start scanning in which initiation of charge accumulation in the photoelectric converter proceeds in series across the photoelectric converter at a speed that is based upon a movement speed and direction of the light shielding member of the mechanical shutter, and (b) reading scanning of the electrical charges accumulated in the photoelectric converter, wherein the controller determines a scanning start time to initiate the charge accumulation start scanning and a travel start time to initiate a start of movement by the light shielding member of the mechanical shutter based upon an exposure time and a delay time, the delay time being equal to a difference between a time when the light shielding member of the mechanical shutter is instructed to begin moving and a time when the light shielding member of the mechanical shutter actually,begins to move.
