Color-processing device, image-forming device and color-processing method

摘要

A color-processing device includes a storage section which stores reference data including reference values set for respective representative color values selected within the range of a predetermined number of gradations of a predetermined color for each of representative output parts selected from a predetermined number of output parts, a first specifying section which specifies an output part corresponding to the input value, a second specifying section which specifies a representative output part corresponding to the specified output part, a third specifying section which specifies a representative color value corresponding to a color value indicated by the input value, an obtaining section which obtains reference values corresponding to combinations of the specified representative output part and representative color value, and a calculating section which calculates an output value corresponding to the input value by interpolation using the obtained reference values.

1. A color-processing device for correcting a color value of a predetermined color to be output from any of a predetermined number of output parts based on an input value, wherein the output parts are arranged in a predetermined direction and the predetermined number is three or more, the device comprising:
a storage section which stores reference data including a plurality of reference values set for a plurality of respective representative color values for each of a plurality of representative output parts, wherein the representative output parts are selected from the predetermined number of output parts, the number of the representative output parts is less than the predetermined number, the representative color values are selected within a range of a predetermined number of gradations from a minimum color value to a maximum color value of the predetermined color, and the number of the representative color values is less than the predetermined number of the gradations; a first specifying section which specifies an output part corresponding to the input value; a second specifying section which specifies, from among the representative output parts, a representative output part corresponding to the output part specified by the first specifying section; a third specifying section which specifies a representative color value corresponding to a color value indicated by the input value; an obtaining section which obtains, from the storage section, the reference values corresponding to combinations of the representative output part specified by the second specifying section and the representative color value specified by the third specifying section; and a calculating section which calculates an output value corresponding to the input value by interpolation using the reference values obtained by the obtaining section.
