摘要： An input color signal is converted into an output color signal fitting into an output device with a combined color conversion table that a to-be-combined (black adjustment) color conversion table and a normal-use color conversion table depending on the output device are combined. As a unit for generating the to-be-combined color conversion table, there is provided a unit for changing an output RGB value corresponding to an input RGB value (a value close to black) determined to be in a predetermined target range of black adjustment, out of output RGB values in a dummy color conversion table in which no color conversion is made, to a value making it more blackish. The generated color conversion table is combined with the normal-use color conversion table.

摘要： A feature amount converting unit performs a color conversion of an input data. A history storage unit stores history information about a measurement of a color chart including conversion values of measured values of the color chart. An arithmetic unit compares the history information with new input information for measurement of the color chart, and determines the number of color patches based on a result of the comparison. A profile updating unit updates a printer profile based on a determined color chart data, and stores the printer profile in the history storage unit.

摘要： An image forming device includes a density correction unit that corrects density based on a density detection value of the density correction pattern; a first density correction pattern generating unit that generates a first density correction pattern having low resolution; and a second density correction pattern generating unit that generates a second density correction pattern having high resolution. When a first density detection value of the first density correction pattern is greater than a predetermined threshold value, the density correction unit corrects the density by determining a density correction reflection rate, based on the first density detection value. When the first density detection value is less than or equal to the predetermined threshold value, the density correction unit corrects the density by determining the density correction reflection rate, based on a second density detection value of the second density correction pattern.

摘要： An image processing apparatus includes a plurality of color conversion tables for color-separation-limited printing. Using a color conversion table for color-separation-limited printing, a piece of input color information corresponding to chromatic color within a specified applying hue range for a specified specific color is converted into a piece of output color information corresponding to color having hue of the specific color, and a piece of the input color information corresponding to color outside of the applying hue range is converted into a piece of the output color information corresponding to gray color. Each of the color conversion tables for color-separation-limited printing is configured such that color values corresponding to saturation and lightness of the output color information are reduced at least in gradation from a maximum saturation part to a low-lightness part.
