Abstract: A control part comprises a division location setting part for setting a division location based on an image data; a scan start position setting part for setting scan start positions of recording heads based on the division location; an image data division part for dividing an image data by the division location; and a head movement control part for controlling movement of the recording heads. The division location setting part sets a division location in a blank area having no pixel to be recorded in the primary scanning direction, in the case of publication printing, in a center margin area between page data. Since the recording heads perform scanning concurrently their respective areas that are divided by the division location, no deterioration in image continuity occurs between the recording heads. This permits an image recorder, though having plural recording heads, capable of performing concurrent recordings without loss of continuity.

Abstract: An optical scanning system and method for laser engraving a plurality of data subrasters into a substrate to form a raster of engraved data defining an image on the substrate. Each subraster has a length dimension and a width dimension. The system includes a transport assembly having an objective lens and a mirror, the mirror capable of reflecting a substantially collimated scanning beam incident thereon in a direction transverse to an axis of the incident beam such that it is directed to the objective lens. The objective lens is capable of focusing the scanning beam on the substrate to engrave a set of data in the width dimension of the subraster and the objective lens and mirror combination is capable of moving along the axis of the incident beam to allow subsequent engraving of other sets of data in the width dimension until a complete subraster is formed along its length dimension. The objective lens and mirror combination is also capable of returning to its starting position to begin engraving of a subsequent subraster of the plurality of subrasters forming the raster of engraved data. A thermoset plastic substrate is also identified as being particularly suitable for use with the aforementioned system and method.

Abstract: An apparatus capable of modification of an image prior to scanning by a scanning device having a scanning element, a viewing surface, a glass platen, and a controller having memory capability, includes opaque adjustable bounding strips. The bounding strips are viewable through the viewing surface of the scanning device and are located between the inside surface of the glass platen and the scanning element. The bounding strips are movable to identify a selected portion of an image to be scanned. The apparatus also includes software for performing a scan of the selected portion of the image and identifying its location, based on the location of the adjustable bounding strips.

Abstract: A digital camera has first and second light sources for sequentially illuminating a document from two different directions in response to the camera being activated. The camera has first and second sensor portions. Only the first and second sensor portions respectively respond to images reflected from the document in response to the first and second sources illuminating the document. Images detected by the first and second sensor portions are combined to remove specular reflection from the document image. In a second embodiment, the camera has three sensor portions.

Abstract: This invention is directed toward a system and method for scanning a scene or object such as a whiteboard, paper document or similar item. More specifically, the invention is directed toward a system and method for obtaining a high-resolution image of a whiteboard or other object with a low-resolution camera. The system and method of the invention captures either a set of snapshots with overlap or a continuous video sequence, and then stitches them automatically into a single high-resolution image. The stitched image can finally be exported to other image processing systems and methods for further enhancement.

Abstract: An image-recording apparatus 1 comprises image recording assembly 60 and a control section 40 having image-processing section 44. The image-processing section divides the image data indicative of the complete image into a plurality of image data pieces indicative of divided images, detects two adjoining divided-images that individually have a joint portion and adjoin each other at the respective joint portions, in the divided images indicated by the divided image data pieces and rotates one of the adjoining divided-images so as to make a recording direction of one of the adjoining divided-images opposite to a recording direction of the other adjoining divided-image. The control section controls the image recording assembly so that a recording medium carries in one direction during recording all divided-images. The divided images are recorded on the respective recording-media one by one to form a plurality of output images. The plurality of output images configure one complete image.
