ABSTRACT:
A camera is provided that accomplishes a warning display using a range measurement frame indicating a specific subject field region. The camera includes a shake amount detection system that detects the amount of shaking of the camera, a drive system that drives the correction lens to effect shake correction and a movement amount detection system that detects the amount of movement of the correction lens. The camera may also include a lens MPU and a camera MPU. The lens MPU determines whether or not shaking has been negated through driving of the correction lens accomplished by the drive system. When shaking has not been negated, the lens MPU outputs a warning signal. The camera MPU sends a signal to the warning display system upon receiving this output warning signal to cause a range measurement frame to flash.
