Abstract:
An image reader apparatus includes: an image pickup device which is controllably exposed to an object to produce an image signal of the object; a mover which moves the object and the image pickup device relative to each other; a storage operable to store an image signal; a writing device which is operable to write an image signal in the storage; a reading device which is operable to read an image signal from the storage; a discriminator which discriminates whether one of the writing device and the reading device is in operation; and a controller which controls the exposure of the image pickup device in accordance with a result of the discriminator.
Abstract:
An image reading apparatus having an illuminating device for illuminating a film original, an image reading device for reading an image on the film original illuminated by the illuminating device and outputting image signals. The image reading apparatus further includes a type discriminating device for discriminating whether the film original is a first film original or a second film original having different film sizes, and a reading scope modifying device for modifying the reading scope of the image reading means according to the result of discrimination of the type discriminating means.
Abstract:
A scanner having a film image fetching unit for reading images from developed film, a cartridge film holding unit and 135 film holding unit which are freely attachable or detachable to or from the film image fetching unit, a convex part formed on each of the cartridge film holding unit and 135 film holding unit, and a plurality of switches to be turned on or off when pressed by the convex part. Based on the outputs of the switches, the present or absence of a film holding unit or the type of mounted film holding unit is identified. The film image fetching unit performs inherent setting such as setting of a range of image reading according to the result of the identification.
Abstract:
An image input apparatus includes an original holder for holding an original, and a reading device for optically reading an image on the original held by the original holder. The original holder has an original holding member for fixedly holding the original, and a frame member for rotatably holding the original holding member.
Abstract:
An optical scanning apparatus for retrieving digital electronic images representative of opaque and transmissive objects. The apparatus is equipped with a reflective scanning platform for scanning documents and photographs and a docking port for receiving a transmissive scanning platform for scanning transparencies and slides. A scanning camera equipped with light sources for illuminating the respective platforms may be aligned by the operator to retrieve images from either the reflective scanning platform or from the transmissive scanning platform. An optical switch which is included within the optical pathway selectively toggles the view of the scanning camera between the reflective platform and the transparent platform. An operator using a control panel button or software can selectively scan either type of object. The choice of two scanning platforms optimizes the digital image quality for each type of media.
Abstract:
An image scanning device is provided with simplified operation. A document holder has reference marks and/or a positioning frame so a document, such as a film or film slide, can be repeatably placed in an accurate position on the document holder. The document can be pressed between two flat plates of transparent material on the document holder to keep the document flat. The image scanning device has a door that need not be manually opened or closed. The document holder is inserted into the image scanning device through the door and is accurately mounted to a movable stage. The stage contacts the document holder so the document holder is positioned on the stage in the same position every time the document holder is mounted to the stage. The stage can also be positioned such that the stage is fixed to a case containing the image scanning device. By fixing the stage to the case, damage to the stage and other support devices is avoided during shipping or transport.
Abstract:
An image input system includes an image input device having a movable carriage and a feeder removably attached to the image input device. The image input device performs a reading action of image information from a source document loaded onto the carriage. The image input device uses a single opening for loading and discharging the film mounts to prevent double loading. The feeder loads the source document onto the carriage during a loading action and discharges the source document from the image input device during a discharging action. A controller controls the operation of the image input device and the feeder. The controller operates a detection system to detect the presence of a film mount remaining in an image input device.
Abstract:
An image input system having an image input device and an original holder that can read images from different configurations of original documents. An image input device includes a light emitting assembly that irradiates light onto an original document, a reading assembly that reads and composes the reading light passing the original document into an image and an assembly for moving the reading assembly and the original document relative to each other to scan the reading light over the original document. The original holder includes a cartridge housing component for housing a film cartridge. The original holder can be removed from the image input device, making possible the reading of images from different kinds of original documents.
Abstract:
An apparatus providing the capability to scan media at different resolutions is presented. The apparatus comprises an image area which is disposed between scanner lid and a scanner base, the lid is pivotally attached to the base to provide easy access to the image area. A light source resides within the scanner lid. Two separate light paths are provided, the first fight path is reflected off opaque targets, through the lid before entering the base and onto an array of photosensitive devices. The second light path is passed through transparent media, into the base and onto the array. First and second focusing lenses are provided, each for a light path. The focusing lenses provide two separate magnifications which yield two separate resolutions.
Abstract:
A scanner system digitizes 35 mm transparencies or negatives, and converts the image to a format compatible with popular microcomputer systems. This scanner system can accommodate various formats, and has variable zoom, pan and window size. Color separation is accomplished by an illumination arrangement causing rapid sequential generation of red, green and blue components. A low wattage light source is used, and color balance is achieved by adjusting the respective exposure times of the three primary colors. The system has internal calibration to achieve repeatable color balance. The system implements a wide variety of color coding schemes ranging in resolution from 1 to 24 bits. An adaptive process compresses the data in order to optimize the color selection process. The illumination optics are anamorphotic for high efficiency. Mechanical and electrical interfaces are compatible with a conventional 51/4" floppy disk drive standard.
