摘要： A focus detecting device which performs focus detection in such a manner that an image of an object formed through an image forming lens is received by an array of many electric charge storing type photo-sensors and, under such a condition, the image is electrically scanned by extracting, in a time serial manner, the output of each photo-sensor, and then the sharpness of the image is detected from a scanning output thus obtained; or that two images of the object which are formed through a range-finding optical system with an apparent parallax corresponding to distance to the object are received by different arrays of such photo-sensors respectively and, under such a condition, the two images are electrically scanned separately from each other by extracting, in a time serial manner, the output of each of the photo-sensors and scanning outputs thus obtained are compared with each other to detect the relative parallax of the two images. In this device, for making the scanning output of the photo-sensor array or arrays always correct irrespective of variation in the brightness of the object, the scanning recycle time duration of the photo-sensor array or arrays is automatically adjusted according to the brightness of the object; and, accordingly, the electric charge storing time of each photo-sensor in the photo-sensor array or arrays are automatically adjusted thereby.

摘要： Disclosed is a device for detecting an incident position of radiation beam, particularly, its center or center of gravity. The detecting device is provided with a scanning type radiation beam sensing device having a plurality of radiation sensing elements in a linear arrangement, and the sensing device is disposed in such a manner that its radiation receiving surface may be substantially coincided with an incident surface of the radiation beam to be detected. When reading an output from the sensing device, the time sequential output signals from the sensing device are split into predetermined sections, and the signal quantities among the sections are compared. In this way, the position of the center or the center of gravity of the radiation beam on the incident surface is detected with the position corresponding to a split point of the signals as the reference.
