Abstract: Image data gathered by a scanner portion is stored into an image file, and stored into a hard disc. A client terminal requests a copy server to send management information of the image files in the hard disc. A control portion that receives the file management information request reads out file management information on the image files in a requested directory, from the hard disc, and sends it to a client terminal. An operator selects an image file on the basis of the management information, and the copy server is requested to down load a corresponding image file.

Abstract: In an arrangement in which an image captured by photography is recorded on new-type photographic film having an information recording zone for magnetically recording information relating to the film or frames on the film, information concerning the aspect ratio of the image is exploited in an effective manner and the aspect ratio is capable of being altered at will. The image recorded on the new-type photographic film and the aspect ratio information in the information recording zone are read by a film scanner. Original digital image data obtained by the reading operation, length X and width Y of the image and effective image size data (length A and width B) generated from the aspect ratio information are recorded on a floppy disk or optical disk by a disk device. When an original image represented by the original digital image data obtained from the floppy or optical disk is displayed, the size thereof is made that stipulated by the effective image size.

Abstract: A photographic film preparation workstation for supplying a high speed photographic printer and an index printer with film image computational data and film encoded data includes a film motion controller subsystem for controlling film movement, a film code reader subsystem for reading optically encoded film data, a magnetics reader subsystem for reading magnetically encoded film data, a film scanner subsystem for scanning film image data and generating a scanned image signal, a magnetics writer subsystem for optionally writing magnetic data to new format films, and a workstation controller in communication with the workstation subsystems for organizing, storing, and distributing subsystem signals.

Abstract: A light source for use in exposing photographic material through a negative. The source includes a plurality of lamps, one appropriate to each emulsion layer of the material to be exposed. Each lamp has a reflector projecting a light stream through a dichroic filter which limits the energy of the stream so that it acts on a single layer. The separate streams are then combined into a single stream which is further treated to eliminate rays exceeding a predetermined angle. Cut off blades may be used to terminate the projection of any one or more of the individual streams for certain definite times depending on the desired exposure of each separate emulsion layer.

Abstract: A durable filter driving mechanism for a color optical reader that is capable of being positively and accurately positioned is proposed. The filter driving mechanism includes a guiding piece mounting thereon a reduction gear assembly having a reduction gear set meshing with a rack of a sliding piece having a rail coupling thereto a color filter assembly operating in cooperation with a lens assembly and a charge coupled element.

Abstract: Subtractive filters are moved into and outfrom the light path between a lamp and a supported color transparency in a color enlarger to provide three separate exposures for the colors red, green and blue. Operator setable means provides an exposure time for each color exposure based on the color density of a standardized transparency. Balance circuit adjusts the exposure time for each color exposure to compensate for differences in color density between the standardized transparency and a transparency from which a color print is to be made. The balance circuit includes a light intensity sensor between the transparency and the lens. Magenta and yellow filters are moved together into the light path to produce the color red. Yellow and cyan filters produce the color green. Cyan and magenta filters produce the color blue. At the end of the red exposure the cyan filter is moved back into the white light path before the yellow filter is withdrawn.

Abstract: A subtractive photographic printer is capable of providing extremely short exposure time by coordinating the operation of a shutter and color filters. The shutter is normally positioned in the light path, and is driven out of the light path at the beginning of an exposure cycle. The exposure in each color channel is terminated by driving the color filter associated with that color channel into the light path in a direction which is essentially the same as the direction in which the shutter was driven out of the light path. In addition, the filter is driven into the light path at essentially the same rate at which the shutter was driven out of the path. The exposure time for the color channel is determined by the time delay between actuation of the shutter drive and actuation of the filter drive, since the shutter and the filter move in the same direction and at essentially the same rate.

Abstract: A microfiche duplicator exposure station where a copy sheet lies facewise over a master while an elongated lamp shines light through the master to expose the copy sheet. A shutter that controls exposure, includes two plates lying over the lamp and a solenoid that quickly pivots the plates to positions beside opposite ends of the lamp to allow light from the lamp to reach the microfiche. The plates have mirror surfaces extending at an incline of about 60.degree. from the vertical when the plates are at opposite ends of the lamp, to shine light onto opposite ends of the microfiche, to thereby compensate for low illumination thereat produced by an elongated lamp.

Abstract: An exposure controlling apparatus for electrophotographic copying machines comprises an operating member which is operable externally of the machine to control the amount of exposure. The operating member is normally biased to return to its neutral position, but can be temporarily held in its operative position when operated. The temporary retention is released upon completion of a copying operation, allowing the operating member to return to its neutral position.

Abstract: The device for correcting the color of a color film printing machine, equipped with three different optical filters which divide the diaphragm hole of an optical system condenser on three segments and two leaves, which partially stop down the filters; at the same time the leaves are suitably equipped with curved guides and pivot around points. Every pair of leaves is driven by a common lever equipped with a slide, which at the lever pivotal point, moves along guides. The linear increases of the lever turning angle is accompanied with a logarithmic increase of the filter-active field, for example, with a suitable radius of curvature, the guides, the length of lever, coordinates of the leaves', pivot points of lever, coordinates of pivot points of leaves, of the distance between the edge and the point of the leaves' pivot point, and coordinates which define the position of the guide curvature center in relation to the leaf edges.

Abstract: Color corrections are executed in a bidirectional film printer responsive to units of color correction information arranged on a data storage tape in the sequence in which the color corrections are to be made in the forward direction of film transport. Units of frame count information each representing the frame at which a color correction is to be made are interleaved with the color corrections on the tape in the sequence in which the color corrections are to be made in the forward direction. One color correction and one frame count at a time are retrieved in pairs; the same pairs are retrieved in both directions of film transport. The frames of the master film are counted during transport and compared with the frame count retrieved from the tape to provide the frame indications at which the color corrections are to be made in the forward direction of film transport.
