Abstract: During electronic film development, an area of conventional photographic film is scanned several times using a single scanning station, and at each subsequent time this scanned area is advanced incrementally along the film with multiple levels of overlap with previous scans. The new image scanned at each new time is aligned to an accumulating image that has been extrapolated to the image at the new time, and then the new image is added to the accumulating image in parametric summations that allow an image to be interpolated to any time free of seams where the scans overlap. The invention further teaches a method of steering the alignment by warping the leading edge of the alignment, and a registration method of aligning multiple images that takes advantage of known fixed alignments between images.

Abstract: A device for driving an endless belt of the present invention includes a drive roller and a roller pair adjoining the drive roller at a side where a photoconductive element is positioned and contacting the belt. The eccentricity of the drive roller and that of the roller pair are reduced to reduce the variation of belt speed when the drive roller is controlled at a preselected angular velocity. Even when the drum is eccentric, the device stably operates integrally with the belt without any slip or oscillation.

Abstract: For dividing an image and recording divided images on a photosensitive film with a plurality of laser beams, an auxiliary scanning speed is reduced in the vicinity of junctions between adjacent ones of the divided images to adjust the intervals between main scanning lines, and each of the main scanning lines is divided into divided main scanning lines in a main scanning direction, and the divided main scanning lines are formed separately in an auxiliary scanning direction. With such a correcting process, a high-quality image free of striped artifacts and inclination differences of main scanning lines can be recorded on the photosensitive film.

Abstract: An image scanner with an image correction function generates a primary image and an auxiliary image of a document. The image scanner includes an image sensing module, a lens module, a scanning platform, a primary light source and an auxiliary light source. The primary light source illuminates the document from a first optical angle and the auxiliary light source illuminates the document from a second optical angle. During alternate illumination by the primary and auxiliary light sources, the scanner respectively generates two images for each document, one of which is a primary image and the other of which is an auxiliary image. The auxiliary image, which includes information concerning damage to the document, is used to correct the primary image, either transmitting the images to a host for further processing, or by processing the images within the scanner.

Abstract: An adding portion superposes a density signal (a signal having its level changing in accordance with a density of a printed image) from a density signal generator with a carrier signal (a signal in the form of a sine wave having a prescribed frequency and a prescribed amplitude) from a carrier signal generator to generate an engraving signal. A stylus included in an engraving head 21 reciprocates according to the applied engraving signal to engrave cells on a gravure cylinder rotating in the main scanning direction. A sub-scanning motor moves the engraving head in a sub-scanning direction perpendicular to the main scanning direction every time cells for one line in the main scanning direction of the gravure cylinder have been engraved. The movement of the engraving head 21 in the sub-scanning direction is controlled so that cells adjacent in the sub-scanning direction partially overlap with each other in every other line.
