Abstract
PURPOSE: To make possible re-photographing by displaying the hand blur at each operation of shutter.
CONSTITUTION: Output of either of stationary, moving mirrors 1, 2 is converted 41 to an electric signal which is then applied to a gate 6 and delay circuit 5. The delay time is matched to shutter operation time and an LED 7 is driven by the output obtainable from the gate 6 according to the difference between the delayed output and the converted output. As a result, the discrimination of hand blur may be accomplished.
