Abstract

PURPOSE: To obtain an automatic camera-shake warning device, by providing an operator being attached to the camera body to detect vibration of camera body when releasing the shutter, and judge if the camera is shaking large enough to influence the photography.
CONSTITUTION: An operator 5 calculates an aperture value and shutter speed necessary for obtaining a proper exposure on the basis of exposure information 7, and displays the results in a finder 9. When a release switch SW is depressed, the operator 5 delivers an exposure control output 8 to perform exposure operation. At this time, if the vibration detection signal Eact inputted through an amplifier 2 is larger than the reference signal Eref, a comparator 4 outputs a camera-shake signal into the operator 5, and a camera-shake warning display 13 is indicated in th finder 9. Therefore, whether the taken photograph has been blurred by camera-shake or not may be confirmed, so that proper countermeasures, such as re-taking or changing of shutter speed, may be taken.
