Abstract
An electrically operated flash camera employs an infrared pre-flash reflected light signal stored in a single memory storage to control focus and aperture. Two comparators serve to govern both operations, sensing potentiometrically derived analog position indicating signals representing lens position and aperture setting as the lens and aperture control elements are scanningly driven through their ranges of settings. Comparison of these analog signals with the stored signal is used to terminate scanning to set focus and aperture. A visible light photosensing means controls aperture and inhibits the exposure flash if ambient illumination is adequate.
