  • Patent number: 5623327
    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.

  • Patent number: 5444509
    Abstract: A camera shake compensating camera compensates for detected results of camera shake and calculates the actual amount of shake occurring in the camera through the differentiated value of the detected result of camera shake and a previously established time delay. This camera is equipped with a camera shake detection device, differentiation circuits, amplifying circuits, adding circuits, a motor driving circuit, a compensating lens, a motor, and photographic lenses. Calculating the amount of camera shake compensation is accomplished by detecting the camera shake with the camera shake detection device and outputting the amount of shake. Then, a first differentiation circuit time-differentiates the amount of camera shake, and a second differentiation circuit time-differentiates the output of the first differentiation circuit.
