Patent ID: 8107140

Claim:
A color processing apparatus comprising: an image signal acquiring section that acquires an image signal including an input color signal belonging to an input color space having at least a first color component; a storage section that stores tone correction information used in tone correction for the input color signal; a normalizing section that reads the tone correction information from the storage section, calculates a first value of the first color component of the input color space based on the input color signal and a maximum value of a second color component of an output color space being different from the input color space, calculates a second value of the first color component of the input color space based on the input color signal and a minimum value of a third color component of the output color space, and normalizes the read tone correction information in accordance with the first and second values of the first color component of the input color space; and a tone correction section that converts the input color signal into a corrected color signal using the normalized tone correction information; and a color converting section that converts the corrected color signal into an output color signal belonging to the output color space.
