  • Patent number: 7180543
    Abstract: An imaging apparatus including a device for discharging charge or F/E-IC for discharging charge accumulated in an imaging device or CCD and for canceling exposure in a discharging term of the charge. The apparatus also includes a light shielding device or mechanical shutter unit for a mechanical shutter, which shields light by the mechanical shutter, and a control device or CPU block for controlling the discharging term of the discharging device and the light shielding timing of the mechanical shutter. The charge discharging term of the CCD in the discharging device is shortened and a light shielding timing of the mechanical shutter in the light shielding device is hastened by the control device or CPU block, when a computer exposure time computed by the control device or CPU block for recording a subject is shorter than an image recording term of one frame.
