摘要： A method of detecting focusing conditions used for optical machinery is disclosed. The focusing conditions of an optical image projected onto photodetector arrays arranged on both sides of the focal plane with a certain optical distance are detected based on an evaluation function representing a sum of absolute values of differences between output signals of adjacent photodetectors. When a value of a first evaluation function represented by the largest absolute value is less than a predetermined threshold a second evaluation function represented by a sum of the maximum and next largest absolute values is used thereby detecting the focusing conditions for a graded image.

摘要： In a method and apparatus for detecting focus condition of an imaging optical system, the focus condition is detected in accordance with a combination of two different detection methods such as an image sharpness detection and an image lateral shift detection by using first and second light receiving element arrays for the image sharpness detection and a third light receiving element array for the image lateral shift detection. For making the construction of the apparatus compact and simple, these light receiving element arrays are formed on the same semiconductor substrate. Further a light flux dividing prism and a lenticular lens array are formed integrally with each other. According to the focus detection method of the present invention, it is possible to detect the focus condition for various kinds of subjects accurately over a wide range by using both the image sharpness detection and image lateral shift detection even in a range near an in-focus position.

摘要： A focus condition of an objective lens is detected on the basis of a lateral shift of two images formed by first and second light fluxes which are transmitted through right- and left-hand halves of the lens, respectively. In order to separate the first and second light fluxes, there is arranged an array of triangle prisms each having first and second surfaces which are inclined symmetrically with respect to the optical axis of lens by a critical angle so that one of the light fluxes is transmitted through the one of the surfaces, but is totally reflected by the other surface of each prism. The first and second light fluxes transmitted through the prisms are received by an array of light receiving elements in such a manner that the first and second light fluxes are selectively received by odd and even numbered light receiving elements, respectively.

摘要： An automatic exposure control circuit comprises a pair of lamp circuits for displaying the fact that an automatic exposure is feasible and the exposure period which is automatically determined, as well as an electronic shutter circuit and an automatic shutter release circuit, and optionally a color temperature measuring circuit. The control circuit is associated with a photomicrographic apparatus which takes a picture of a specimen being observed in a microscope. When taking a picture, a photometry is made of light from a specimen being photographed in order to determine initially whether an automatic exposure control is feasible for the specimen, and if it is feasible, to provide an automatic release of an electronic shutter by means of a motor, thereby activating the electronic shutter and also producing a lamp display during the period when the electronic shutter is operating. Optionally, a color temperature of the light from a light source which is used to irradiate the specimen is measured.

摘要： An intelligent copier for readily performing image enlargement, reduction, synthesis, and editing. In the intelligent copier, an SIT (Static Induction Transistor) image sensor in which a plurality of SIT image cells are arranged two-dimensionally pixel by pixel in the same substrate is used as an image sensor for picking-up the image of a document. It is not necessary to use an expensive mass storage memory for storing the image information, because the SIT image sensor can perform a nondestructive readout, so that the copier can be made small in size and inexpensive in cost.

摘要： In a chemical analyzing apparatus of a colorimetric type in which a light flux transmitted through a test liquid is made incident upon a light receiving element through an optical filter having a predetermined transmission spectrum range and a measurement signal is obtained by processing a photoelectrically converted signal, a plurality of optical filters having different transmission spectrum ranges and arranged side by side and a solid state image sensor having a plurality of light receiving elements each having a photoelectric converting element and a static induction transistor are arranged one upon the other. An analytical result is obtained by calculating output signals selectively derived from light receiving elements which are arranged behind a particular optical filter having a transmission spectrum range related to a wavelength determined by a test item to be studied. Since use is made of a static induction transistor, it is not necessary to change the optical filters mechanically and is possible to read out the necessary output signals having high S/N selectively in a prompt manner, while the levels of output signals can be monitored.

摘要： In a single-lens reflex camera having an objective lens, a focusing screen and a view finder, a photodetector array is arranged to receive a central part of an object image formed by the objective lens and a focusing condition of the objective lens is detected by calculating an evaluation function from image signals supplied from the photodetectors. A presetting dial for selecting given photodetectors whose image signals are used for detecting the focusing condition is provided at such a position that a part of the dial is exposed to the outside through an opening formed in a rear wall of a camera body at a position underneath a film winding lever. A light emitting diode array is provided on the focusing screen so as to be seen by a user through the view finder. Only desired light emitting diodes are lighted on under the control of a signal supplied by the dial to indicate the region of the photodetector array which is used for detecting the focusing condition.

摘要： An information reading apparatus for reading information includes a board having a plane optical waveguide and a light source on the board. Light beam emitted from the source is conducted by a first optical system to a predetermined direction through the waveguide. Part of the light beam is deffracted toward a second optical system by a surface elastic wave region formed in the waveguide. The second optical system conducts the light beam to an information recording region of a card through the waveguide and leads reflected light beam from the information recording region to a photodetector. The light beam not diffracted by the elastic wave region is conducted to a third optical system formed in the waveguide. The system conducts the light beam to a synchronizing signal recording region of the card and leads reflected light beam from the synchronizing signal recording region to a photodetector.
