Abstract
A camera shake correction system which uses a combination, of electronic and mechanical camera shake correction devices so as to be able to realize an excellent camera shake correction. The camera shake correction system includes a mechanical camera shake correction part as well as an electronic camera shake correction part. The mechanical camera shake correction sensor uses as a camera shake sensor a picture image sensor used in the electronic camera shake correction part, thereby eliminating the use of an expensive angular velocity sensor. On the other hand, when an angular velocity sensor is used, the zero angular velocity detected by the picture image sensor is used to set the off-set voltage of the angular velocity sensor. Also, at least one of the following, tilting and panning operations of a camera is decided in accordance with the output of the picture image sensor or the outputs of the picture image sensor and angular velocity sensor, the electronic and mechanical camera shake correction parts that are suitable for the operation decided are controlled. Further, by proper or selective use of the electronic and mechanical camera shake correction parts in accordance with the…
