Abstract: A scanner system digitizes 35mm 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 5-1/4" floppy disk drive standard.

Abstract: A colour slide transparency scanner projects an intense stripe of light through a colour slide. Red, green, and blue filters (22) successively filter the stripe of image from the slide. In some applications, a neutral density filter adds still more information from dark areas of the slide image. A carriage (34) carrying the slide moves across the light. A CCD array (23) detects the filtered images and converts them to analog electrical signals. Circuitry (26) converts the analog signals into digital form.

Abstract: A slide mount supply device supplies plural slide mounts (17,171). Each of the slide mounts includes a reversal photo film piece (17a) having an image frame. A mount panel (17b) is disposed about and secured to the photo film piece. In the slide mount supply device, a cartridge (14) has a tubular shape, and contains the plural slide mounts stacked vertically. A feeder mechanism (30) with a claw portion feeds a lowest slide mount (171) among the plural slide mounts to an outside of the cartridge. Furthermore, a path base member (33a) is disposed downstream from the feeder mechanism, and on the path base member, the slide mount (17,171) being fed is passed. A recess (56) is formed in the path base member, has a smaller size than a size of the slide mount in a direction crosswise to a feeding direction thereof, for preventing interference between a middle portion of the slide mount and the path base member if the middle portion is bulged.

Abstract: The image scanning system of the present invention scans slides and film strips containing photographic images and creates a corresponding plurality of digital representations of the photographic images. The system includes a touch screen monitor, a computer (54), a scanner (62), a high speed interface and a printer. The scanner includes a light source for projecting light through the film strip. A light sensor senses the light projected through the film strip and generates pixel data. A film drive advances the film strip between the light source and the light sensor. A lens located between the light source and the light sensor directs the light projected through the film strip onto the light sensor. The pixel data is transmitted through the high speed interface to the computer for processing operations. After the pixel data has been processed, digital images are displayed on the monitor and may also be printed out.

Abstract: An image in a slide mount (17, 91) is pre-scanned while a mount holder (36) with a slide mount (17, 91) is conveyed from a scan start position to a scan end position. In the middle of the reverse movement of the slide mount (36) after the pre-scan, the slide mount (36) is stopped to carry out focusing operation, and fed back to the scan start position. Based on the scan condition determined by calculation during the focusing operation, the image is fine-scanned to obtain image data while the slide mount (36) is conveyed to the scan end position. A sort card (34, 93, 94, 95) for dividing slide mounts (17, 91) for each order has identification openings (34a, 93a, 94a, 95a). The identification openings (34a, 93a, 94a, 95a) are formed in the middle of all sides in order to detect the sort card (34, 93, 94, 95) even when the sort card (34, 93, 94, 95) is turned over or loaded in incorrect orientation direction.
