ABSTRACT:
A camera which compensates for vibrations to reduce image blur by shifting an image blur suppression lens. The image blur suppression lens is movable in directions perpendicular to the optical axis of the camera. An interrupter detects the position of the image blur suppression lens and produces a position detection signal having change points occurring to indicate the position of the image blur suppression lens. A timer produces a count value and a memory device stores the count value of the timer when a change point occurs in the position detection signal. A control device determines the displacement velocity of the image blur suppression lens from the count value stored in the memory device. In this manner, the accuracy and efficiency of the computation of the displacement velocity is improved.
