Image processing device, image processing method, and image processing program recording medium

摘要

An image processing device comprises: a first output device having a first color gamut and outputting an image based on a given first color reproduction target value; a second output device having a second color gamut and outputting an image based on a second color reproduction target value; a color gamut information acquirer for acquiring a first color gamut information relating to the first color gamut of the first output device and a second color gamut information relating to the second color gamut of the second output device; and a target value generator for producing a second color reproduction target value for the second output device by correcting the given color reproduction target value for the first output device based on acquired first and second color gamut information by the color gamut information acquirer.

1. An image processing device comprising:
a color gamut information acquirer for acquiring a first color gamut information relating to a first color gamut of a first output device and a second color gamut information relating to a second color gamut of a second output device; a target value acquirer for acquiring a first color reproduction target value for the first output device converted from a given input color signal so as to be allocated to the first color gamut; a color gamut difference calculator for calculating a difference between the first color gamut of the first output device and the second gamut of the second output device based on the first color gamut information and the second color gamut information acquired by the color gamut information acquirer; and a target value generator for producing a second color reproduction target value for the second output device by correcting the first color reproduction target value for the first output device so as to be allocated to the second color gamut of the second output device based on the color gamut difference calculated by the color gamut difference calculator and color information of the given input color signal.
