摘要： A meter sensitivity pattern control method for cameras in which an output of a first light metering circuit for the brightness of an object of principal photographic interest is compared with outputs of a plurality of second light metering circuits for brightness of different portions of the environment surrounding the object by a corresponding number of comparing circuits. Thereby one second light metering circuit having an output which lies in a predetermined range different from the output of the first light metering circuit and another second light metering circuit having an output which lies outside the predetermined range are selected for their different contributions to an exposure value. The thus-differentially weighed outputs of the second light metering circuits are computed with the output of the first light metering circuit producing light value information.

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.

摘要： In an automatic continuous focusing device, two detected images of an object formed by a distance detection optical system with a relative distance therebetween associated with the object distance are scanned, the obtained scanning signals are quantized to generate quantized picture element data, the relative distance between the two detected images is detected on the basis of the quantized picture element data, and an imaging optical system to be focused on the object is controlled according to the detection result. The device also provides for invalidating the control of the imaging optical system when the results of detection of the quantized condition of the scanning signals indicate that the quantized condition of the scanning signals for at least one of the two detected images is not sound or reasonable.
