ABSTRACT:
An automatic image stabilization device which is arranged to detect image movement information from a sensed image signal produced from an image sensor and to reduce the image movement comprises a movement detecting circuit which obtains movement vector information for each of a plurality of parts of an image plane, and a weight setting circuit arranged to attach weight to each movement vector information and to vary the weighting degree according to photographing conditions. A camera using this device is arranged to correct the shaking of the camera on the basis of the result of a computing operation performed on a camera shake detected from the signal produced from the image sensor together with a camera shake physically detected by means of an accelerometer.
