摘要： A focus detection system is provided in which an image of an object is projected onto an array comprising a plurality of light acceptor elements, formed by photoelectric elements, to cause them to produce photoelectric signals in accordance with the distribution of light intensity of the image. The photoelectric signals are converted into digital equivalents, and an absolute magnitude of a difference between digital signals of adjacent elements is calculated. These absolute magnitudes are arranged in the sequence of their magnitude, and a given number of them is accumulated, starting from the largest one. The accumulated value is utilized as the value of an evaluation function which indicates the sharpness of the image.

摘要： A device for automatically detecting a proper focusing state of an image-forming optical system e.g. for a photographic camera such as a single-lens reflex camera and the like, comprises a mechanism for splitting a beam of light incident through the optical system. The device does not depend intrinsically upon a current state of polarization of the incident light-beam.The mechanism for splitting a beam of light comprises a two-component lens arrangement which divides the incident beam of light into two beams of light, and a phase-shifting plate behind one of the components for lengthening the effective optical path of one of the split beams with respect to the other split beam. A first a second array of light-sensing elements is provided for receiving both of the split beams of light for evaluating and comparing the sharpness and other characteristics of the two beams of light.
