Color processing apparatus and color processing method

摘要

A display controller displays, on a display device, a color to be adjusted used to adjust a display color, and a plurality of candidate colors which define a first color range including the color to be adjusted, all of which are instructed by a user. A selector selects one of the plurality of candidate colors based on a user instruction. The display controller displays the selected candidate color as the color to be adjusted on the display device, and also displays, on the display device, a plurality of candidate colors which define a second color range including the color to be adjusted. The second color range is narrower than the first color range.

主权项

1. A color processing apparatus for performing an adjustment of display color of a display device, the apparatus comprising:
a display controller configured to display, on the display device, a target color to be adjusted, which can be designated by a user, and a plurality of candidate colors that may be selected by a user in preference to the target color, which candidate colors define a first color range including the target color to be adjusted; and a selector configured to select one of the plurality of candidate colors based on a user instruction, wherein the display controller displays, subsequent to selection of one of the candidate colors, on the display device a further plurality of candidate colors which define a second color range including the selected candidate color as a second target color to be adjusted, and wherein (a) the second color range is narrower than the first color range, (b) the candidate colors define vertices of the color range, (c) the target colors to be adjusted are respectively located at a center of each of the first and second color ranges, (d) each of the first and second color ranges is a chromaticity range on a device-independent color space, and (e) the display controller sets a narrower second color range by narrowing down the previous second color range at a predetermined ratio in response to a selection of a candidate color in the second color range.
