摘要： First intermediate data is generated from print data and character edge data serving as second intermediate data is generated by extracting edge sections of a character from the print data. A rendering process is applied to the first intermediate data and a dither matrix with a first number of lines is used to apply a pseudo halftone formation process to data after the rendering process to generate a first pseudo-halftone image. A rendering process is applied to the second intermediate data and a dither matrix with a second number of lines greater than the first number of lines is used to apply a pseudo halftone formation process to data after the rendering process to generate a second pseudo-halftone image. A pseudo-halftone image obtained by an OR operation of the first pseudo-halftone image and the second pseudo-halftone image is output.

摘要： An image forming apparatus is provided that can provide a natural edge processing even if a toner save processing and a line width correction processing are configured in parallel. The image forming apparatus detects an edge neighboring region of an input image in a predetermined direction. The edge neighboring region detected by the neighboring edge detection step is subjected to a line width correction processing. An edge region of the input image in a direction other than the predetermined direction is detected. Then, a toner save processing is performed on a no-edge region that is a region other than the edge region detected by the edge detection step.

摘要： Methods and systems herein provide for halftoning of Run length (RL) encoded datastreams. In one embodiment, a print controller identifies a packet within a RL encoded datastream. The packing includes a header and a block of continuous tone data. The print controller identifies an array of conversion values for converting RL encoded data to halftone data, and indexes the array using one or more bytes of the block of bitmap data. The print controller then outputs halftone data from the conversion array based on the index to convert the RL encoded continuous tone data of the packet to halftone data for a print engine.

摘要： An image forming apparatus and an image forming method are used to smoothly process an edge area of halftoning-processed binary data. The image forming apparatus may include a communication interface which receives printing data, a binarizer which performs halftoning with respect to the received printing data to generate binary data, an edge processor, and a printing engine which forms an image by using the edge-processed binary data. The edge processor calculates an edge strength of each white pixel of the generated binary data, determines edge candidates, determines whether an edge candidate is an edge, and substitutes a black pixel for a white pixel determined as an edge to perform edge processing with respect to the generated binary data.

The method further includes determining the number of levels on the basis of the asymmetric printer resolution, selecting for each level a collection of at least one binary pattern, each binary pattern consisting of a plurality of sub-pixels the number of which is determined by the number of levels, selecting for each pixel of the halftoned image a binary pattern from the collection selected for the level assigned to the pixel, transforming each pixel of the halftoned image into the selected binary pattern, and printing the binary patterns of the transformed pixels using the asymmetric printer resolution. A printer is configured to perform the method.

摘要： The prior art has such a problem that image quality degrades because dots are conspicuous in the case where the size of each dot is not so small and the black or white dots are regularly aligned, in particular, in a bright part close to white or in a dark part close to black. It is determined whether a black or white pixel exists at a point-symmetric position with respect to a notice pixel using pattern matching for a binarized image and in the case where a pixel exists at the point-symmetric position, the notice pixel is replaced with a specific output pattern.
