<p>PURPOSE: To recognize that a camera-shake correction can be detected or not on a camera body side by deciding whether camera shaking can be detected or not with a camera-shake detecting part and transmitting the signal of the decision from a lens barrel to the camera body. CONSTITUTION: The output of an angular velocity sensor 5 detecting the angular velocity of the vibration caused by the camera shaking is connected to a microcomputer 4 in the lens barrel 2 with a sensor circuit. When a release button is half depressed to turn on a half depressed switch, the supply of power to the lens barrel 2 is starred and a microcomputer 3 executes photometry based on the measured object luminance and rang-finding based on a distance up to an object after a temperature is measured, then, transmits a lens state command to the lens barrel 2 and further receives camera-shake detection data from the lens barrel 2. Then, the microcomputer 3 decides whether the camera shaking can be detected or not based on the received camera-shake detection data and transmits a vibration proof starting command to the lens barrel 2, when the camera-shake can be detected, to start vibration proof control.</p> |
