Image processing techniques for color correction

摘要: Each pixel of an input image is subjected to first color conversion by means colorimetric reproduction and converted a device value target space. Further, difference DI between white luminance originating space pixels the calculated. When generating output image, with 0 keeps For greater than 0, second calculated as being sum abovementioned which obtained multiplying coefficient that less or equal 1. Due this, when from space, can be reproduced more brightly while achieving coincident appearance.
