摘要： A photo-electric converting device includes storing parts which store electric charges obtained through a photo-electric conversion process respectively from reflected light received when light projection is performed by light emitting apparatus and another reflected light received when no light is projected by the light emitting apparatus. The device computes storage signals produced from the storing parts and detects an electric signal which corresponds solely to reflected light resulting from light projection performed by the light emitting apparatus.

摘要： A visual field searching device is arranged to divide the visual field to be searched into a plurality of intermediate fields each of which is larger than a constituent unit field; to select, for each of the intermediate fields, a typical or representative object distance data from among object distance data obtained for individual constituent unit fields included in each intermediate field; further, for each intermediate field, to discriminate whether the representative distance data thus selected is in a predetermined relation to other object distance data; and after that, to perform a signal processing operation to obtain necessary information by processing only the number of data representing the intermediate fields instead of processing all the data for all the constituent unit fields.

摘要： The disclosed distance measuring device is arranged to project light on an object. Reflected light from the object is received by a photo-electric converter to shift the position of a photo-taking lens to an in-focus position on the basis of a signal produced from the photo-electric converter. The projected light and/or the reflected light is divided into a multiplicity of light fluxes for the purpose of broadening and simplifying the distance measuring range and accuracy.

摘要： An automatic focusing device of a camera capable of photo-taking in infrared ray has means for detecting a focus condition of an imaging lens and correction means for producing information representing a difference between a focusing point of an image formed by a visible ray and a focusing point of an image formed by an infrared ray. The imaging lens is selectively moved to an in-focus position for the visible ray or an in-focus position for the infrared ray based on the focus information from the focus detection means and the correction information from the correction means.

摘要： A focusing state discriminating system of the invention discriminates the focusing state of an image forming optical system, based on signals F1, F2 and F3 representing image formation states of images formed at first, second and third positions of the optical system which substantially correspond to positions slightly in front of, coincident with and slightly behind the predetermined focal plane of the image forming optical system. The operation for discrimination in this system includes at least a comparison of .vertline.F1-F3.vertline. and K(F1+F2+F3), where K is a constant.

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.
