摘要： In the disclosed system shifting light-measuring modes are shifted by restricting the view angle of a light sensitive element or by producing differences between a first light measuring circuit and a second light measuring circuit, each having a different light measuring range. A correction circuit determines aperture corrections for mode changes. When the exposure is controlled, the output of the light measurement is corrected by the output of the correction circuit.

摘要： In the device disclosed, an image formed by an optical system is scanned by an image sensor composed of independently arranged photoelectric transducing elements to produce an image scanning signal. A detecting circuit detects the variation of the brightness between the adjacent image elements as a measure of the sharpness of the image and the focus of the optical system. The focus detection accuracy is improved by non-linear transformation of the brightness variation signal with a non-linear transformation circuit that weighs the brightness variation signal on the basis of the signal level. A signal forming circuit detects the difference between the outputs of transducing elements and adds the differences to produce a comparator signal when a predetermined relationship is reached between the sharpness indication and the addition signal. An indicator indicates that the focusing condition cannot be discerned in response to the comparison signal and a control inhibits the output of the detection circuit to the indicator prior to the addition signal.
