摘要： The present invention relates to a method and a system for detecting the sharpness of the object image by detecting the amount of the component of a certain specified frequency, whereby the object image formed by means of an image forming optical system is detected by an image sensitive element consisting of a number of fine photo sensitive elements arranged respectively integrated on one plane, while the outputs of the above mentioned photo sensitive elements are delivered out one after another in accordance with the arrangement order of the above mentioned elements by means of a signal time series means so as to carry out an electrical scanning of the above mentioned object image in such a manner that the then obtained scanning outputs of the object image are successively converted by means of an A - D (analogue-digital) converting means into digital signals which are put in a small computer in which an estimation function for estimating the amount of the component of a certain specified frequency in the spectrum of the spacial frequencies of the object light beam forming the above mentioned object image is programmed in advance.

摘要： A range finder system to detect distance to an object by irradiating radiation toward an object, a distance to which is to be detected based on the principle of a base line range finder and receiving radiation being reflected by said object. It is particularly characterized by that a distance to an object is detected by irradiating a photoelectric conversion means with radiation and then comparing the signal outputted by said photoelectric conversion means with a prescribed reference signal. And the system of the present invention has, for that end, a radiation generation source to generate radiation, a light receiving system being positioned with a prescribed base line distance from said radiation generation source for receiving the reflected radiation being emitted by the radiation generation source and reflected by the object, a photoelectric conversion means to take in the radiation from said light receiving system being reflected by said object, an oscillating device having such function as intermittently irradiating the above mentioned photoelectric conversion means with the radiaton reflected by the above mentioned object within the radiation path between said photoelectric conversion means and the above mentioned radiation source, a reference signal generation means to generate reference signal, and a signal comparison means to compare the signal generated by the above mentioned photoelectric conversion means and the above mentioned reference signal.
