摘要： A method of filtering an input image is provided. In a creating action, a boolean tone map is created based on the input image and an array of tone nodes. In a determining action, it is determined whether or not a target pixel is in a tone region by examining the target pixel and a neighboring region of pixels. If the target pixel is in a tone region, in a selecting action, a first base-filter is selected for the tone region. A method of resolution dependent filtering is also provided.

摘要： In one embodiment, a plurality of target pixels within a digital representation of an image are selected, and a corner gradient pattern is determined for each of the target pixels. The corner gradient pattern is analyzed to classify the target pixel as an edge pixel or a non-edge pixel. If the target pixel is a non-edge pixel, target pixel is replaced with a plurality of non-edge output pixels. If the target pixel is an edge pixel, the target pixel is replaced with a plurality of edge output pixels, including determination of an orientation of an edge, and selection, based on the orientation, and application of a filter kernel to produce the edge output pixels to replace the target pixel.

The image is printed on the sheet of media with the ink, in accordance with the ink-usage parameters. Adjustment of ink-usage parameters and printing an image on a sheet of media with the ink are repeated for each additional image to be printed on a sheet of media.

摘要： A method of compressing a set of image data organized into a matrix of pixels includes selecting a multi-pixel block portion of the data, then performing a mathematical function on the multi-pixel block portion to generate a first result. The multi-pixel block portion is divided into at least two segments, and a function is performed on each of the segments to generate a second result and a third result. Based on a comparison of the first, second, and third results, determining whether or not to compress the multi-pixel block portion. The function may be a deviation or mean measurement and serve to determine the noise level and image detail level to determine whether to compress or divide the block into sub blocks. Sub blocks may be recursively analyzed for compression or subdivision until all sub blocks are compressed or divided into single pixels.

摘要： Tone dependent plane dependent error diffusion halftoning takes into account multiple color planes, such as cyan and magenta, when determining the placement of a dot in any of the color planes. The combined tones of the correlated color planes is used to determine the threshold levels against which the combined tones and the accumulated errors for the correlated color planes is compared. Further, tone dependent error weightings are determined based on the combined tones of the correlated color planes. The tone dependent error weightings are used to diffuse the final accumulated errors for each color plane. A prerendered mid-tone bitmap may be used to break up any structured patterns that occur in the mid-tones. Using this technique, printed dots of two or more colors are dispersed so as to avoid noticeable clumping of dots of two or more colors to provide a more uniform pattern and to avoid the unintentional overlapping of colors. This technique can be used to augment any existing error diffusion method.

摘要： An embodiment of a halftoning method reduces the grainy appearance resulting from overlap of cyan and magenta colorants using a single threshold matrix for both the cyan and the magenta color planes. The cyan color value and the magenta color value for a pixel are summed. If the sum is greater than the maximum possible color value by at least the corresponding matrix threshold value, both cyan and magenta colorants are placed on the pixel. If the sum is not greater than the maximum possible color value by at least the corresponding matrix threshold value, then the smallest of the cyan color value and the magenta color value is compared to the corresponding matrix threshold value. If this smallest color value is greater than the corresponding matrix threshold value, the corresponding colorant is placed on the pixel. Otherwise, the other colorant is placed on the pixel. If the sum is less the maximum possible color value, then the sum is compared to the corresponding matrix threshold value. If the sum is greater than the corresponding matrix threshold value, colorant will be placed on the pixel. The smallest of the cyan color value and the magenta color value is compared to the corresponding matrix threshold value. If this smallest color value is greater than the corresponding matrix threshold value, the corresponding colorant is placed on the pixel. Otherwise, the other colorant is placed on the pixel.
