Abstract
A camera includes a vibration detecting sensor for detecting a vibration of the camera, a correcting device for correcting a shake of an image due to the vibration, a focus detecting circuit for detecting a state of focus by using information about the image, and a controlling circuit for controlling the correcting operation of the correcting device according to the state of focus detected by the focus detecting circuit.
Claims21
A camera comprising:
- image pickup means;
- vibration detecting means for physically detecting a vibration of a camera body;
- correcting means for correcting a motion of an image due to the vibration on the basis of information about the vibration detected by said vibration detecting means;
- focus detecting means for detecting a state of focus on the basis of a predetermined signal component of an image signal output by said image pickup means;
- and
- controlling means for controlling a correcting operation of said correcting means according to the state of focus detected by said focus detecting means to prevent an erroneous focal adjustment by said focus detecting means.
