<p>PURPOSE:To take a blurring-free photograph, by instructing a shutter holding means to cancel the shutter holding near the peak of camera-shakes in accordance with signals from a camera-shake detecting means. CONSTITUTION:A camera-shake quantity detecting means 48 starts detection by means of an acceleration sensor when the 1st stroke switch is turned on. A camera-shake peak value calculating circuit 49 starts calculation when the 2nd stroke switch is turned on and differentiates acceleration signals from the means 48. At the time when the differentiated acceleration signals become zero, the circuit 49 outputs a signal for cancelling shutter holding to a shutter holding circuit 50. The circuit 50 outputs a shutter holding signal to a shutter driving circuit 46 and causes the circuit 46 to hold a shutter in a just-before-run state and, when the shutter holding cancelling signal is inputted from the camera-shake peak value calculating circuit 49, to cancel the shutter holding. Thus the shutter is run.</p> |
