摘要： This invention presents a range finding device when 1st and 2nd detection images of an object are scanned by signal storing type image sensing means to obtain image scan signals, which are quantized by quantization means to produce quantized image data for said 1st and 2nd detection images. On the basis of the thus obtained quantized image data, the location within the 2nd detection images of one set of M successive elements of the 2nd detection image which is most similar to M successive elements of the 1st detection image is detected, and with the aid of the data of this location, the distance between the device and the object is determined. According to this improved device, sequence control means, which controls a series of operations for range finding, will firstly cancel the signals stored in said image sensing means as unnecessary signals, when said series of operations is initiated, and then enables proper storing of image signals in the image sensing means so as to properly control the device.

摘要： This invention relates to a device for focus detection or distance detection in which one or more images of a target formed by an optical system are received by photoelectric light receiving means to obtain a photoelectric output regarding the imaging condition of the image of the target and this photoelectric output is electrically processed through a processing circuit to thereby provide an electrical output representing the focus adjusted condition of the optical system with respect to the target or the distance to the target. According to the improvements of the present invention, such device is provided with projector means for illuminating a limited part of the detection view field determined by the focal length of the optical system and the dimensions of the effective light receiving surface of the photoelectric light receiving means, detection means for detecting whether or not the signal put out by the photoelectric light receiving means regarding the imaging condition of one or more images of the target is a sufficiently proper signal to ensure accurate focus detection or distance detection by the processing circuit, and control means for controlling the projector means in accordance with the detection output from the detection means. When proper detection is not ensured during the focus detection or the distance detection, the projector means is driven by the control means in accordance with the detection output of the detection means and the projection image of the projected light formed thereby on the target is utilized to effect focus detection or distance detection.

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： A device for detecting the positional relationship between first and second objects in a predetermined direction includes a light source for emitting light in a direction to the first or second object, and a first detecting portion for detecting the position of incidence of a first light deflected by the first and second objects, wherein the position of incidence of the first light upon the first detecting portion is changeable with a change in the positional relationship between the first and second objects in the predetermined direction. A second detecting portion detects the position of incidence of a second light deflected by at least one of the first and second objects, wherein the state of the position of incidence of the second light resulting from a change in the positional relationship between the first and second objects, in the predetermined direction differs from that of the first light. On the basis of the detection by the first and second detecting portions, the positional relationship between the first and second objects is detected without being affected by an inclination thereof.
