Abstract: A scanning apparatus for scanning and recording a color image. A source of light having a certain flicker rate illuminates the color image, and a scanning element, such as a charge-coupled device, scans the color image during scanning periods to generate electrical signals which are representative of the color image. Each of the scanning periods is equal to the reciprocal of the flicker rate to eliminate effects of the flicker on the electrical signals. A color filter with different-colored filter segments located between the scanning element and the color image enables the scanning element to produce electrical signals which are representative of different colors in the color image. The color filter is rotated at a rate such that each filter segment is interposed between the scanning element and the color image for a rotation period which is greater than the reciprocal of the flicker rate. The electrical signals are integrated in the scanning element for a first period (e.g., 8.

Abstract: A digitizing scanning apparatus for scanning and recording an image in digital format for ultimate reproduction. The apparatus comprises a base and an upstanding tower structure. At least one scanning element, such as a charged coupled device, is carried by an outwardly extending arm on the upstanding tower structure. A source of light is carried by another outwardly extending arm on the upstanding tower structure and is moveable with the scanning element so that there is a constant field of light on any portion of an image as it is being scanned. The apparatus utilizes a pair of horizontal support rods with a unique bearing structure such that a carriage which enables movement of the tower structure is essentially self-aligning and properly supported with a minimum amount of frictional effects. Moreover, the tower structure is removable from and connected to the base housing by merely inserting a neck of the tower structure into a pocket associated with the base housing.

Abstract: A photographic film printer that forms an image on film based upon received or stored digital information is provided. While maintained in a stationary position, the film is exposed in a sequence of raster scans by a rotating disk traversing the photographic film surface. At least one optical film is attached to the rotating disk in a manner that transmits optical energy directed towards the center of the disk to a peripheral location on the disk. Exposure of the film occurs by controlling the emission of optical energy by the fiber in accordance with the received or stored digital information as the peripheral edge of the disk rotates past the film surface.
