Abstract
PURPOSE: To display camera-shake when releasing the shutter, by detecting the vibration of camera body when releasing the shutter, digitizing the vibration detection signal, and comparing with the vibration judgment reference signal depending on the shutter speed.
CONSTITUTION: A CPU8 calculates an aperture value and shutter speed necessary for obtaining a proper exposure on the basis of exposure information F, and displays the results in a finder 10. When a release switch SW is depressed the CPU8 delivers an exposure control output G to perform usual exposure operation. A vibration detector 1 outputs a signal a, which is digitized by AD converter 3 to become signal Ad. If this signal Ad is larger than reference signal B, a deviation output C is outputted from a comparator 7. Receiving this output, the CPU8 sends a confirmation signal E to a display unit 9 after taking photograph, and presence or absence of blur by camera-shake in the present photograph is indicated in the fnder 10 by confirmation display.
