Abstract: A light emission and reception system for optical biometric measurement includes a light radiator and a light receiver. The light radiator radiates source light to a living body. The light receiver receives return light scattered from the living body. The light radiator and the light receiver are disposed at an end face of the system which is to be put into contact with a surface of the living body. The system measures biometric data of the living body based on intensity of the light detected by the light receiver. The light receiver comprises segments at different angular ranges around a center axis of the light radiator, and/or the light radiator comprises segments at different angular ranges around a center axis of the light receiver.

Abstract: There is described an image reading apparatus that reads image information from a document, such as a negative film, a photographic prints, etc., on which image information is recorded. The image-apparatus includes a plurality of light sources for emitting lights, wavelengths of which are different relative to each other; an image-reading section to read the image by detecting either transmitted lights or reflected lights, which are obtained by irradiating the lights emitted from the plurality of light sources onto the image recorded on a document; and a light-amount adjusting section to independently adjust each amount of the lights emitted by the plurality of light sources, when the image-reading section reads the image.

Abstract: There is described a method of processing an image recorded on a film, by which differences of gamma values between RGB image information and information on foreign substances or damages are corrected. The method comprises the steps of: irradiating a plurality of lights, whose wavelengths are different relative to each other, onto the film; reading the image by detecting the plurality of lights transmitted through the film or reflected from the film placed, so as to generate a plurality of color image data sets corresponding to a plurality of color images included in the image; and processing the plurality of color image data sets, so as to keep each of relative relationships or each of ratios, between gamma values of the plurality of color images, substantially constant.

Abstract: An image recording apparatus comprising: a film loading section in which a first film and a second film having a width which differs from that of the first film can be loaded; a detecting means which detects a film width and outputs detection signals; a conveyance means for conveying said films; a conveyance control means which controls said conveyance means in accordance with said detection signals; and a light source which irradiates the first film or the second film conveyed by said conveyance means and thereby projects light corresponding to an image formed on the first film or the second film on a light-sensitive material.

Abstract: An image recording machine has a plurality of light sources capable of emitting light independently for exposing a part of a photographic film without causing double exposure and with a printing controller. At least one of the light sources is caused to flash continuously for printing codes for timing during film transport, other light sources are caused to flash in synchronization with flashing of the light source for printing codes for photographing information, and the light source for printing the codes for photographing information is caused to flash for printing reference codes which are to be the judgment standards for the codes for photographing information.

Abstract: A processing machine to process information recorded on a photographic film to be processed in the form of plural information. When information contents relating to the same processing item are recorded both in the form of information that is possible to rewrite and in the form of information that is impossible to rewrite, the photographic film is processed based on the form of information that is possible to rewrite.
