Abstract:
1. A color processing apparatus for adjusting a table which indicates a correspondence between color data dependent on a source device and color data dependent on a destination device, the apparatus comprising: a storing section, configured to store the table for converting color data of grid points in a color space of the source device into color data in a color space of the destination device, and to store generation information used in generation of the table; an input section, configured to input adjustment conditions of the table, which include a color to be adjusted, a color range influenced by adjustment and defined by an upper color value and a lower color value, and an adjustment amount, wherein the color to be adjusted is designated on a color space different from the color space of the destination device, the color range is designated on a color space different from the color space of the destination device, and the adjustment amount is designated on a device independent color space; a first converter, configured to convert color data, which is stored in the table and is dependent on the destination device, into color data on the device independent color space using the generation information, wherein the color data corresponds to the color to be adjusted and is included in the color range; an adjustor, configured to apply the adjustment to the color data converted by the first converter in accordance with the adjustment amount; a second converter, configured to convert the color data, to which the adjustment is applied, into color data dependent on the destination device using the generation information; and a replacement section, configured to replace color data, which is stored in the table and is dependent on the destination device, with the color data which is converted by the second converter and is dependent on the destination device, wherein the adjustor adds the adjustment amount to the color data in the device independent color space corresponding to the color to be adjusted, and adds values, which are obtained by weighting the adjustment amount according to distances between the color to be adjusted and colors included in the color range, to color data which are included in the color range and are converted by the first converter.
