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 telephoto type objective comprising a front lens group and a rear lens group axially spaced apart from each other. The front lens group has a positive refracting power and which remains stationary during focusing. The rear lens group has a negative refracting power and is comprised of two movable lens members for focusing. When the two movable lens members are moved along the optical axis toward an image plane, the telephoto type objective is caused to focus an object at a near distance from its focusing on an object at a far distance with the resulting amount of movement of the rear lens member being larger than that of movement of the front movable lens group.

摘要： A view finder system for a single lens reflex camera which provides in the field of the finder an image of a photographic information indicator such as a distance adjusting ring, diaphragm adjusting ring and the like movably mounted in the lens barrel which is connected to the camera body. The view finder includes a pentagonal roof prism in combination with supplementary optical means optically connected thereto, said supplementary optical means comprising a sub-prism having an exit face cemented to the front non-reflecting face of the pentagonal roof prism, an entrance face and a reflecting face, and a mirror element spaced apart from the sub-prism. The mirror element is arranged above the sub-prism to face down optically both the indicator and the sub-prism, so that a light beam from the indicator is reflected by the mirror element to the sub-prism and thereby directed through the pentagonal roof prism to provide an image of the indicator in the field of finder.
