摘要： An image processor includes a first data acquiring unit, a second data acquiring unit, a third data acquiring unit, a convergence point setting unit, and a converting unit. The first data acquiring unit acquires first color data that is included in a first color gamut. The second data acquiring unit acquires second color data having a highest chroma of a second color gamut. The second color gamut has a middle point on an achromatic axis. The third data acquiring unit acquires third color data that is located on the achromatic axis and that is closer to the middle point than a point on the achromatic axis having the same lightness of the second color data. The convergence point setting unit sets a convergence point for the first color data on a first line segment defined between the second color data and the third color data. The converting unit converts the first data into fourth data that is included in the second color gamut by moving the first data in a direction toward the convergence point.

摘要： In an image processing apparatus, the generating unit generates print data indicating whether a dot having one of a plurality of sizes is formed or not, by performing a halftone process on original image data. The correcting unit generates corrected print data by correcting the print data. The dividing unit divides the edge part data of the print data into a plurality of block data. The index value determining unit determines, for each block data, an index value relating to an amount of ink to be used based on the plurality of dot data included in the each block data. The changing unit changes, for each block data, the size information of at least one dot data among the plurality of dot data included in the each block data based on the index value such that the amount of ink to be used becomes reduced.

摘要： The image processor processes each pixel of a halftone image by sequentially setting each pixel as a target pixel. A converting unit converts a pixel density of the target pixel into a first output value. An error data calculation unit calculates error data of the target pixel. The error data corresponds to a difference between the first output value and the pixel density. A compression unit irreversibly compresses the error data of the target pixel. Partial data of the pixel density is lost from the error data when irreversibly compressing the error data. An error buffer stores the compressed error data of the target pixel and a plurality of sets of compressed error data for a plurality of processed pixels. A decompression unit reads and decompresses a plurality of sets of compressed error data for a plurality of peripheral pixels with respect to a next target pixel from the error buffer. A density correction unit corrects a pixel density of the next target pixel based on the decompressed error data sets for the plurality of peripheral pixels. The converting unit converts the corrected pixel density of the next target pixel into a second output value. A data compensating unit compensates the partial data.

摘要： An image processing device includes: a process section; a generation section; and a supply section. The process section includes: an index value determination section; and an adjustment section. The index value determination section is configured to determine an index value for each of a plurality of target pixels included in edge image data. The adjustment section is configured not to adjust a pixel value of the target pixel in a first case where the density of the target pixel is determined to be relatively low based on the index value of the target pixel, and configured to adjust the pixel value of the target pixel so as to reduce the density of the target pixel in a second case where the density of the target pixel is determined to be relatively high based on the index value of the target pixel.

摘要： An image processing device includes an original image data acquiring unit and a reducing unit. The original image data acquiring unit acquires original image data indicative of an original image. The original image data includes a plurality of sets of original pixel data, the original image having a first resolution and a first size. The original image is divided into a plurality of original grids. Each original grid corresponds to a set of original pixel data. The reducing unit creates reduced image data by performing a reduction process on the original image data. The reduced image data includes a plurality of sets of reduced pixel data. The reduced image data indicates of a reduced image having a second resolution lower than the first resolution and a second size same as the first size. The reduced image is divided into a plurality of reduced grids. Each reduced grid corresponds to a set of reduced pixel data. The reducing unit includes an acquiring unit and a reduced pixel data producing unit. The acquiring unit acquires, for each set of reduced pixel data, at least one set of original pixel data satisfying a following condition that the at least one set of original pixel data corresponds to the original grid whose part is superposed on the reduced grid corresponding to the each set of reduced pixel data when the reduced image is partially superposed on the original image such that the reduced image is shifted, from a original position at which the reduced image is entirely superposed on the original image, by a prescribed length shorter than a length of one original grid. The reduced pixel data producing unit produces the reduced pixel data by calculating a weighted average of the at least one set of original pixel data acquired by the acquiring unit based on size ratio, each size ratio being defined as a ratio of a size of the part of original grid that is superposed on the reduced grid corresponding to the reduced pixel data to a size of the reduced grid.
