摘要： Embodiments of a computer-implemented method for thin-line enhancement in electronic images are disclosed. The methods include receiving a halftone image comprising multiple pixels, and associating a predefined kernel with at least a portion of the halftone image. The kernel includes multiple check cells and a processing cell, each capable of being toggled between an active state and an inactive state; detecting a state of each of the pixels in the neighborhood of an inactive pixel associated with the processing cell based on one or more predetermined rules being applied to the kernel, wherein the inactive pixel is in communication with a contiguous set of active pixels; and selectively activating the inactive pixel by activating the processing cell based on the predetermined rules, provided the inactive pixel upon being activated is separated from a neighboring active pixel.

摘要： A methodology for thin line detection and enhancement in electronic images is disclosed. The methodology includes associating an electronic image with at least one basic context window that is less than the size of the electronic image based on the input image resolution of the electronic image; detecting one or more predefined patterns which correspond to thin lines in the electronic image using the at least one basic context window; excluding patterns for the one or more detected patterns which are halftone patterns; and adding at least one pixel to the electronic image based on at least one of the remaining patterns so as to enhance thin line features in the electronic image. In some implementation, the methodology may be configured to handle electronic images having different resolutions. A system for thin line detection and enhancement in electronic images having different resolutions is also disclosed.

摘要： An information processing method includes inputting bit information, temporarily storing at least part of the input bit information, and detecting whether the stored bit information coincides with one predetermined feature of plural such predetermined features. Print information for an object pixel which corresponds to a stored bit is modified in a case where coincidence is detected. Modification may include, for example, contour retention in a case where a rectangular portion is detected, line width discrimination, or white line discrimination. In addition, second feature detection can determine that a right-angled portion is not involved, in which case print information is modified only if coincidence is detected with plural predetermined features and a right-angled portion is not detected.

摘要： A system for performing edge enhancement of mixed low resolution image files employs a binarization and sorting unit to sort data that is indicative of binary data from the mixed low resolution image input file. The sorted binary data is then supplied to a binary data edge enhancement processor for edge enhancement processing. The output from the binary data edge enhancement processor unit is supplied to a data merger unit along with the original image data. The data merger unit determines whether the original image data was part of a gray-scale image. If the data merger determines the original data is part of a gray-scale image, the original data is supplied as the output of the processing system. If the data merger determines that the original data is binary image data, the output from the binary edge enhancement processor unit is supplied as the output of the processing system.

摘要： A printer driver has a single filter. The filter includes a program for constructing a pipeline consisted of a plurality of stages based on a print ticket. In one or more of the plurality of stages, a content box of print-target data is modified. When the content box is modified, commands respectively indicating affine transformation matrices are generated. The commands are pushed into a command stack. The pushed commands are used for modification of a visual element. Specifically, the affine transformation matrices are multiplied and thereby an integrated transformation matrix is generated. The visual element is modified by multiplying an affine transformation matrix of the visual element by the integrated transformation matrix.
