Camera shake correction system

A shake correction system adapted for use with a camera having a photographing optical system having a plurality of optical members, comprising:

• a picture image sensor for detecting the amount of parallel movement of a following picture image with respect to a leading picture image in accordance with picture image data between fields or part of said picture image data;
• electronic camera shake correction means for moving a picture image to be output in a direction opposite and parallel to that of the parallel movement detected by said picture image sensor by the amount of parallel movement detected by said picture image sensor;
• an angular velocity sensor for detecting an angular velocity produced by the shake of the camera, and for outputting a signal corresponding to said angular velocity;
• and
• mechanical camera shake correction means for driving at least one of said plurality of optical members of said photographing optical system of the camera in accordance with the output of said angular velocity sensor, said one of said plurality of optical members being disposed within said camera such that said one of said plurality of optical members is freely movable, wherein said electronic camera shake correction means exclusively performs shake correction within a predetermined range of values of a movement vector between the following picture image and the leading picture image.
