摘要： This specification discloses a focusing screen adapted for use with the range finder of a camera, particularly a split image type focusing screen. This screen comprises a pair of portions desposed in the center of the real image plane of the camera, and each portion has a refracting means and a diffracting means. Thereby, in a defocused condition, the images viewed through the portions are split each other and blurred. Further, this screen can be used wth an objective lens having a small aperture ratio.

摘要： A camera having a holographic indicator in which a focused image hologram is held on an image plane of the view finder of the camera and a light source is arranged to illuminate the hologram in such a direction that the light transmitted through the hologram goes out of the path of the view finder. The hologram may be also a relief type blazed hologram which has a transmitting factor (zero-order diffraction factor) higher than 90% for the light from an object and which makes the light from the reconstructed image of the hologram pass through the path of the view finder. This hologram indicator never affects the object's image when the hologram is not illuminated.

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： 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.

摘要： This specification discloses a focusing screen adapted to be mounted in the range finder of a single lens reflex camera. A diffraction lattice is provided in the focus indicating part of the focusing screen. The diffraction lattice comprises a periodical arrangement of optically asymmetric unit structures in which +1st diffracted light and -1st diffracted light assume a color-complementing relation, and in the defocus (out of focus) condition, double images colored in two colors mutually having a color-complementing relation are produced. Further, this diffraction lattice structure is such that the period directions are opposite to each other in the upper and lower half areas of the focus indicating part and therefore, the manner of coloring is inversely symmetric in the upper and lower areas and color split occurs even at the bondary between these areas. These phenomena disappear when the focus condition is brought about.

摘要： A phase type diffraction grating and a microprism for splitting the light beam from an objective lens into three light beams. The three light beams are split in one direction by the diffraction grating and are directed onto three rows of line sensors disposed on the same plane. In the two optical paths between the diffraction grating and the line sensors, there is disposed an optical path length difference imparting element for forming on the line sensors images at a predetermined focal plane of the objective lens and planes forward and rearward of the predetermined focal plane. Thus, the line sensors detect the images at the predetermined focal plane and at planes forward and rearward of the predetermined focal plane.
