Abstract

We developed the method to adjust a display to a predetermined state and to make ICC display profiles with human eyes. In our method, in order to measure the tone reproduction curve of a display device, the brightness and hue of a continuous tone image is adjusted to the brightness and hue of a binary image. In addition, for measuring the complex curve, three pairs of images having different values of brightness are used. Furthermore, the color of the display white is adjusted to the color of a white object under the viewing illuminant to adjust the display white for any viewing illuminant. To bear out the color matching accuracy of our method, two kinds of experiments were carried out for three LCDs, and three subjects. First, we measured the chroma of gray. The result was that the chroma of the display adjusted by our method was smaller than the chroma of the un-adjusted display. Second, we simulated the color of DDCP on the display and measured the matching accuracy. Then, our method could reduce the color difference between both devices. These results show the display adjusted by our method has enough accuracy to use for soft proofing.
