摘要： An image processing apparatus includes an image reading unit that reads an image of a document as color image data including pieces of color component data; a dot-component removing unit that removes dot components by smoothing each color component data; a high-frequency-color identifying unit that identifies, of colors represented by dot-removed color component data obtained by the smoothing, a high-frequency color satisfying a predetermined high-frequency condition; an individual-density-conversion-information generating unit that generates, for each high-frequency color, individual-density conversion information for converting each color component data such that a color near the high-frequency color becomes substantially the same as the high-frequency color; and a color-component-data converting unit that converts, based on the individual-density conversion information, each color component data in a part of the color image data, the part being data in which a color represented by the dot-removed color component data is a color near the high-frequency color.

摘要： A document specification is examined to determine if it matches the device color characterization of a rendering device such as a printer. If it matches, then the document can be faithfully rendered by the device. Otherwise, the document specification must be transformed before rendering. A match can be detected by discovering a appropriate metadata within the document specification or within the document color characterization. Alternatively, a device signature can be used instead of a metadata.

摘要： When dividing multi-valued data and generating data for two-pass multi-pass printing, in addition to divided multi-valued data that are divided for each of the two passes, divided multi-valued data that is common to both of the two passes is generated. Moreover, quantized data of that common multi-valued data is reflected onto the quantized data for each pass. Furthermore, when generating quantized data, division ratios that are used when generating the common data by the multi-valued data division described above are set according to the image characteristics (whether or not the area is flesh color) of the multi-valued data. Thereby, it is possible to perform high-quality printing regardless of the image characteristics by taking a suitable balance between suppressing density unevenness and suppressing graininess.

摘要： A data structure comprising a user-maintained list of colors is scanned to determine if a particular color within the user-maintained list of colors has been re-defined. If the particular has been redefined within the user-maintained list of colors, the particular color is searched for and identified in an alternative data structure comprising a user-specified extensible set of alternative colors. The particular color identified in the alternative data structure can then be automatically parsed in order to extract color space and value information associated with the particular color and define image-processing operations involving the particular color. The color space associated with the particular color in the alternative data structure can then be translated to a known color space in order to provide the correct color in the printed output.

摘要： What is disclosed is a novel system and method to reduce noise induced by color mixing in a color management system. At least one device color recipe is obtained for a target spot color. The recipe is defined for a color marking device and defines a range of marking device color values for a target L*a*b color value. Next, a minimal value and a maximum value of each color value in the range of color values for said target L*a*b color value are identified. An iterative process of searching is performed until the printed color test patch produces a visually acceptable smoothness while matching color accuracy. This iterative process includes generating at least one additional new device color recipe from color values within the range of color values. At least one of the new device color recipes is selected and provided to the color marking device for rendering.
