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. A first amplifying circuit amplifies the output of the first differentiation circuit by A1 times, and a second amplifying circuit amplifies the output of the second differentiation circuit by A2 times. Next, a first adding circuit adds the output of the amplifying circuits, and a second adding circuit adds the output of the camera shake detection device and the output of the first adding circuit. Finally, the motor is driven by the motor driving circuit based on the amount of camera shake compensation.
