摘要： Disclosed is a method of detecting the focusing condition of an image forming optical system to an object, in which two images of the object are formed with respective light beams from the prescribed exit pupil areas lying in almost symmetry to each other with respect to the optical axis of the optical system and are sensed to obtain an equal number of picture element data for each of the images, and based on the thus-obtained picture element data, while sequential shifting for the first image is carried out from its one end to its opposite end, and a sequential shifting for the second image from its symmetric one end thereto to its opposite end, each by a predetermined number of picture elements, a correlation betweeen the first and second images in every predetermined equal number of picture elements is sought, whereby an optimum correlation is obtained, the corresponding mutual positional relationship between the above-described predetermined numbers of picture elements is detected to discriminate whether or not the above-described image forming optical system is in focus for the above-described object.

摘要： Disclosed is a TTL (Through-The-Lens) type focus detecting device for use in an interchangeable lens-equipped camera, in which a plurality of lenslets are positioned at or near the prescribed focal plane of the objective lens, each of the lenslets is associated with two or more pairs of photosensitive elements. Upon attachment of an objective lens to the camera body, one of the pairs of photosensitive elements for each lenslet is automatically selected to operate on the basis of the dimensions of the used objective lens. The outputs of the selected pairs of photosensitive elements for all the lenslets are processed to detect whether or not a positional difference between two images of an object formed with light beams from the objective lens at respective virtual exit pupils lying in almost symmetry with respect to the optical axis thereof is present, whereby the detection of whether or not the objective lens is in-focus is indicated.

摘要： A focus detecting system detects an image formation state of an image of an object by processing a time-serial output from a photoelectric transducer element through a high-pass filter. In order to suppress the outputs from the high-pass filter corresponding to the time-serial signal at the initial moment of light reception by the photoelectric transducer element or immediately thereafter, an amplifier is provided which performs the initial setting of the high-pass filter. The input and output ends of the amplifier are connected to parts of the high-pass filter, and the output impedance of the amplifier may be changed in response to a signal from an external source.
