Abstract:
It is an object of the present invention to enable no-margin printing to be achieved without the need to cut off margins, while avoiding a discontinuous output result in which the areas between adjacent print images are missing even if poster printing is carried out. Print data outputted by an input section is stored in an input buffer. One page of print data from the input buffer is inputted to the dividing section. The dividing section divides the one page of print data in accordance with division numbers J and K indicated by an instructing section. The dividing section then outputs the divided print data to a printing section as a plurality of print images. The plurality of print images outputted to the printing section are printed on the respective sheets.
Abstract:
The present invention relates to an apparatus for creating a pattern on a workpiece sensitive to radiation, such as a photomask a display panel or a microoptical device. The apparatus comprises a source for emitting electromagnetic radiation, a spatial modulator having multitude of modulating elements (pixels), adapted to being illuminated by said radiation, and a projection system creating an image of the modulator on the workpiece. It further comprises an electronic data processing and delivery system receiving a digital description of the pattern to be written, extracting from it a sequence of partial patterns, converting said partial patterns to modulator signals, and feeding said signals to the modulator, a precision mechanical system for moving said workpiece and/or projection system relative to each other and an electronic control system coordinating the movement of the workpiece, the feeding of the signals to the modulator and the intensity of the radiation, so that said pattern is stitched together from the partial images created by the sequence of partial patterns. According to the invention the drive signals can set a modulating element to a number of states larger than two.
Abstract:
Apparatus for digitizing images (1) includes a reader device (3), such as a CCD array, having a photo-sensitive surface (4) that comprises a large number of pixels arrayed longitudinally and laterally. The reader device (3) is subjected to a ninety degree rotation and/or linear displacement by a distance of several pixels, as necessary, before and/or during the digitization process so as to provide optimum digital resolution for a variety of image formats.
Abstract:
In reading an original by mounting reading means (scanner unit) on a recording apparatus, the advancing width of the original is so reduced that the reading bands k, k+l, . . . , are partially overlapped. For example in the color image reading, in generating the data of the (k+1)-th band, the data of a range overlapped with the k-th band are corrected by the data of the k-th band (for example by simple averaging), thereby achieving image reading without bandwise density fluctuation regardless of the reading mode and the original size.
Abstract:
A method for the reproduction of oversize documents is disclosed. The method utilized by the present invention copies or scans in stages an oversize document that exceeds the copy or scan surface of the image reproduction apparatus available. Each separate document portion copied or scanned is saved as an image in memory. After all of the oversize document has been copied or scanned, the images of the document portions are reassembled, aligned and reduced in size, if necessary. The reassembled document may then be printed for a user or manipulated in memory using image processing software.
Abstract:
A system for scanning and digitizing large images using an optional reseau for accuracy without obscuring the image to be scanned. The system uses at least one photoreceptor array which is fixed in a rigid position with respect to any accompany lenses and mirrors. In one embodiment, a first CCD photoreceptor array is used to scan the image while a second CCD photoreceptor array simultaneously scans the reseau. In a second embodiment, a single CCD photoreceptor array is used to first scan the reseau and then to scan the image. One illumination source illuminates the reseau while second illumination source illuminates the image. The arrangement of the lens(es) and the photoreceptor arrays allows the determination of any displacement of the scanner along the X-axis, Y-axis, and Z-axis, as well as the determination of any rotation of the scanner around the X-axis, Y-axis, or Z-axis. The position and attitude of the scanner, as determined by scanning the reseau, is used to correct any errors in the resulting image that are caused by displacement or rotation of the scanner. A large image can be scanned in separate but overlapping swaths, the overlap being used to align the swaths to create a final seamless digital image from the assembled swaths.

Abstract:
For the production of a photographic print of an original present in electronic format, optical representations (D) are produced from sequentially changing strip-shaped portions of the original by way of an electro optical, pixel wise operating converter device (3) and these optical representations (D) are projected onto a strip-shaped exposure region (E) on the copy material (P), whereby the strip-shaped exposure region (E) and the copy material (P) are moved relative to one another and at an essentially constant speed in a direction transverse to the longitudinal extent of the strip-shaped exposure regions (E), so that successively the image information of the whole original is exposed onto the total available surface of the copy material (P). Each strip-shaped portion of the original is thereby divided into at least two strip-shaped sections positioned one behind the other in longitudinal direction of the portion, separate optical representations are produced from the sections by way of the electro optical converter device (3) and these separate optical representations of the sections are projected onto the copy material (P) in at least two strip-shaped partial exposure regions (E1, E2) which are positioned one behind the other in longitudinal direction and together form the strip-shaped exposure region (E). A digital micro mirror field is preferably used as the electro optical converter device (3). In this manner, large format photographic prints of high quality can be produced with relatively low constructive cost by using conventional converter devices.
