Abstract: Disclosed are a printing apparatus and method through which high-quality image printing can be performed at all times even if image data is binarized so as to perform pseudo half tone representation and the binarized image is printed by multi-pass printing. The apparatus performs printing in such a manner that the periodicity of a matrix pattern such as a dither matrix for half tone representation and the periodicity of the matrix of a mask pattern, which is used in multi-pass printing, will not coincide. In a case where printing is carried out by a printhead having a plurality of ink discharge nozzles, the printing apparatus is controlled so that printing is performed by assigning a large number of different nozzles to print the same line.

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 radiation source, a spatial modulator (SLM) having a multitude of modulating elements (pixels), a projection system, an electronic data processing and delivery system controlling the modulator and a precision mechanical system for moving said workpiece. Specifically, the pixels could be set in a number of states larger than two, and the electronic processing system is adapted to create one type of pixel map inside pattern features, another type of pixel map outside features, and intermediate pixel maps at a boundary. The intermediate pixel map is generated in dependence on the placement of the boundary in a grid finer than that of the pixels of the SLM projected on the workpiece.

This apparatus comprises: an image memory to store the coded image data; a printer to print the image data; a counter to read out the data from the memory and to count the number of lines of the image data; and a controller to control the printer so as to allow the image data to be divided and printed in response to the count value of the counter. The size data of the image data is compared with the count value and when they coincide, the controller controls the printer. If the image data exceeds the line number of one standard scale recording sheet, the printer is controlled so as to divide and record the image data on two or more recording cut sheets.

Abstract: The present invention relates to a method of reconstructing an image from data captured by a sensor, and is particularly applicable to the case of sequential capture in relative movement between a scanning device and the original image. The seanning device comprises navigation means for detecting the position of the sensor relative to the original image. A pixel grid for the reconstructed image is determined, and correspondence between the pixel grid and the sensor data is identified using sensor position detection data. The intensity of pixels is determined from sensor data selected as relevant to the pixel under consideration.

Abstract: A manual type image scanner rolls on X-direction and Y-direction rollers which support the scanner for translation in X and Y-directions, respectively. The scanner scans a surface while translated in the Y-direction. The X-direction roller is positioned on the scanner so that it is remote from a scanned surface when the scanner is supported on the Y-direction rollers. The position of the X-roller is such that the scanner can be supported on the X-direction rollers by tilting the scanner about one end of the Y-direction rollers until the X-direction roller contacts the surface and further tilting the scanner to lift the Y-direction rollers off the surface. Movements of the X-direction and Y-direction rollers are registered by encoders so that an area wider than an image width of the scanner can be scanned by consecutively scanning adjacent paths by making alternating traversals in the X- and Y-directions.

Abstract: A method and device for acquiring data related to topography of a medium includes projecting light, allowably from more than one direction, onto the surface of the medium at an angle of less than sixteen degrees relative to the surface and imaging the surface. For example, the imaging sensor may be an array of sensor elements that is used to determine navigation of a hand-held scanner along an original. By introducing light at an angle of less than sixteen degrees, surface irregularities cast shadows that form a high contrast illumination pattern along the surface of the medium. The navigation sensor detects multi-element variations of intensity of scattered light from the surface with respect to positions along the surface, so that the Nyquist criteria are adequately satisfied. Typically, the light is collimated incoherent light, but this is not critical. The illumination angle can be established by using a prism. The prism may have an antireflective thin film coating on one or more prism faces. The employment of a prism provides a number of advantages, such as use of a transparent surface in contact with the media and raising the illumination source(s) away from the media.
