Abstract

PURPOSE:To suppress the influence of a hand shake by sending a signal for exposure start indication to a shutter control part from a blurring detector according to the time when the blurring becomes minimum after the time required for preparation from the depression of a release button to the closure of a shutter. CONSTITUTION:When the release button 52 is pressed, a blurring is normally generated, so this blurring is detected by the blurring detector 24 consisting of an acceleration sensor 3, an oscillator 4, and a frequency discriminator 5. A blurring arithmetic part 6 receives data corresponding to blur waveform from the blurring detector 2 and calculate the period of the blurring by utilizing the single vibration of the blurring in its beginning to determine the time when the direction of the blurring changes, i.e. the time when the blurring becomes minimum. This time is contrasted with a preparatory operation time inputted to this blurring arithmetic part 6 previously to calculate a specific time, with which the shutter is driven and opened and closed for an expected exposure time. Consequently, the influence of the blurring is suppressed.
