摘要： A focusing detecting system for discriminating a focusing state of an object lens by detecting a relative positional relation of a plurality of object images formed by light fluxes from the object lens, by photo-sensing means is disclosed. A plurality of object images are formed based on a light flux from a center area of the object lens around an optical axis and a plurality of object images are formed based on a light flux an area in the periphery of the center area around the optical axis, by optical means disposed behind an image plane of the object lens. Light shielding means having a plurality of slits is disposed near the image plane. By those means, a state is which the object images based on the light fluxes from the center area of the object lens around the optical axis and the peripheral area are detectable and a state is which the object images based on only the light flux from the center area of the object lens around the optical axis is detectable are discriminated.

摘要： A camera according to this invention includes a diffracting means disposed in the optical path of the object image forming light for a finder. The diffracting means is illuminated by a light source also provided within the body of the camera so as to exit the diffracted light toward the object side. A person who stands on the object side as an object can ascertain whether or not he is within the area of the object field to be photographed by the camera. Also, in taking a picture of himself with a camera mounted on a tripod using a self-timer, he can, while standing on the object side, obtain information about the self-timer through a photographic lens. According to one preferred embodiment of the invention, as the diffracting means, there is used a volume type phase diffracting means to avoid any adverse effect of the diffracting means on the object image forming light in which the diffracting means is placed.

摘要： The present invention relates to a device for measuring light incident on an image forming optical system, making use of a plural number of the diffraction element. The plural number of the diffraction elements are respectively provided in the optical path of the image forming optical system. Further the plural number of the diffraction elements respectively present a certain predetermined area. The plural number of the diffraction elements, seen along the direction of the optical axis of the image forming optical system, are substantially only partially overlapped with respect to each other. The light beam incident on a diffraction element is divided into a non diffracted light beam and a diffracted light beam. Thus diffracted light beam is directed toward the light detecting means so as to be measured while the non diffracted light beam advances along the above mentioned optical axis. Consequently at the part at which the diffraction elements overlap each other, the non diffracted light beam led out of the preceeding diffraction element again enters the following diffraction element. This light beam is again divided into a non diffracted light beam and a diffracted light beam by means of the following diffraction element. The diffracted light beam is measured by a light detecting means in the same way as in the above mentioned case, while the non diffracted light beam advances along the above mentioned optical axis. Thus the light beam which passes through the overlapping parts is measured a plural number of times.

摘要： In an optical information recording/reproducing apparatus, the reproduction of information is performed as following manner. A light spot is formed on a recording medium on which information is recorded so that a phase of light reflected by a small region as an information pit is different from a phase of light reflected by other regions. Upon scanning the recording medium with the light spot, a leading edge and a trailing edge of the information pit in the scanning direction are respectively detected. A detection signal for the leading edge of the information pit and a detection signal for the trailing edge of the information pit are synthesized to effect the reproduction of information.

摘要： A still image processing method which can execute the effective flowing process is provided. In this method, when the flowing process is executed by shifting some or all of the pixels constituting a still image of one image plane in a predetermined direction, if no image information to be shifted exists at the first image position, the image information from elsewhere in the image plane is shifted to the second image position. The image information at the second image position is obtained by shifting the image information in the image plane in the direction opposite to the principal shifting direction.

摘要： In a focus detecting device, an object's image formed on a prescribed image plane of a photo-taking lens is once again formed by a secondary imaging optical system disposed behind the prescribed image plane into two non-superposed object's images based on light flux portions symmetrically split relative to the optical axis of the photo-taking lens; light sensitive elements are respectively disposed in positions where these images of the object are re-imaged by the secondary imaging optical system; and an in-focus state of the photo-taking lens is arranged to be detected by detecting the relative positional relation of these reformed images of the object by means of these light sensitive elements. The focus detecting device includes light splitting means which is arranged in the secondary imaging optical system to split a light flux coming from the exit pupil of the photo-taking lens into a middle part portion and a peripheral portion. With this arrangement, an object's image which becomes necessary as the F-number of the exit pupil of the photo-taking lens varies or an object's image which permits simultaneous use of another detecting method in the device can be obtained by the secondary imaging optical system.
