  • Patent number: 8253850
    Abstract: In a digital camera, in an automatic shooting stand-by state, when it is judged that an automatic shooting condition has not been satisfied, it is judged whether or not to issue an AE re-processing command (that is, it is judged whether or not the current shooting condition is similar to a condition where the automatic shooting condition is satisfied). When it is judged to issue the AE re-processing command, exposure tracking in an aperture-priority mode is performed, and shooting exposure conditions excluding the aperture value for still-image shooting in the aperture-priority mode are determined. Then, storage is updated. When it is judged that an automatic shooting condition has been satisfied, record processing for still-image shooting is performed with the updated shooting exposure conditions without changing the aperture value.

    Abstract: In a digital camera 1, in an automatic shooting stand-by state, when judged at Step S26 that an automatic shooting condition has been satisfied (N at Step S26), whether or not to issue an AE re-processing command is judged. In other words, whether or not the current shooting condition is similar to a condition where an automatic shooting condition is satisfied is judged. When judged to issue the AE re-processing command, exposure tracking in an aperture-priority mode is performed (S28), and shooting exposure conditions excluding the aperture value for still-image shooting in the aperture-priority mode are determined. Then, the storage is updated (Step 29), and the process returns to Step S26. When judged at Step S26 that an automatic shooting condition has been satisfied (Y at Step S26), record processing for still-image shooting is performed with the updated shooting exposure conditions without changing the aperture value (Step S30).

  • Patent number: 6006040
    Abstract: A shatter device includes an exposure opening. Shutter blades slide in an opening direction to a maximum open position to open the exposure opening so as to provide an exposure. Then the shutter blades slide in a closing direction to close the exposure opening. An opening diameter is determined in accordance with the maximum open position, and is controlled smaller according to highness of subject brightness. A solenoid slides the shatter blades in the opening direction. A position detecting photo interrupter detects a reach of the shutter blades to a reference position while the solenoid slides the shutter blades in the opening direction. A controller obtains a timer time in accordance with the subject brightness, and starts measuring elapsed time in response to a signal from the photo interrupter. The solenoid is turned off when the measured elapsed time comes up to the timer time while the shutter-blades are slid further in the opening direction.
