  • Patent number: 7777802
    Abstract: An AF controlling unit (83) starts an outside light AF operation controlled by an outside AF unit (81) by a half-pressing of a shutter release button (61), and a change over between the outside AF operation and a CCDAF operation controlled by a CCDAF unit (82) is controlled corresponding to an elapsed time t (timer 84) from a starting of the operation of the outside light AF operation and a pressing condition (a detection of the half-pressing by a half-pressed detecting unit (62), the detection of a full-pressing by a full-pressed detecting unit (63) or a press-in releasing) of a shutter release button (61) after the starting of the outside light AF operation controlled by the outside AF unit (81) by the half-pressing of the shutter release button (61).

  • Patent number: 7656457
    Abstract: An imaging apparatus that includes 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 imaging 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 hastening by a predetermined time the charge discharging term of the CCD in the discharging device and a light shielding timing of the mechanical shutter in the light shielding device, when a shutter speed for recording a subject is more than a predetermined time.

  • 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.

  • Publication number: 20070030369
    Abstract: An imaging apparatus comprises a device for discharging charge or F/E-IC (102) for discharging charge accumulated in an imaging device or CCD (101) and for canceling exposure in a discharging term of the charge, a light shielding device or mechanical shutter unit (7-4) for a mechanical shutter (7-4a), which shields light by the mechanical shutter (7-4a), and a control device or CPU block (104-3) for hastening by a predetermined time the charge discharging term of the CCD (101) in the discharging device (102) and a light shielding timing of the mechanical shutter (7-4a) in the light shielding device (7-4), when a shutter speed for recording a subject is more than a predetermined time.
