    … We consider a computer simulation of color confusion for dichromats for any colors on any video device, which transforms color in each pixel into a representative color among the set of its confusion colors. … We show that such a simulation algorithm with the proportionality law is unique for the video displays whose projected gamut onto the plane perpendicular to the color confusion axis in the LMS space is hexagon. …

    昇華型熱転写ビデオプリンタは,その中間調制御部のフルカラー化などにより高画質プリントを実現している.ところが昨今のグラフィック画像やオーバーレイ画像のプリントにおいては,色調の偏りが激しいことにより画像内のグレイバランスがずれてしまう現象が見られる.また同一画像の連続プリントにおいては,最初と最後のプリント画質がわずかに異なり,特にグレイバランスにおいてその差が目立つなどの現象がみられる.そこでこ …
