Abstract:	顯示器之色彩表現，是顯示器廠商的技術指標之ㄧ，但實際上於賣場或生產線上觀察，同一廠商所生產之顯示器，因材料、製程差異、電路調校及光源模組等等的問題，造成不同機器間所呈現的色外貌不同。過去大部分對於色外貌映對的方法均用於解決CRT 與印表機之間的問題，但實際上目前急速發展的顯示器產業亦存在著無法達到相同色外貌保持的問題，但此方面之色彩調校研究較為缺乏。所以在此引進色域映對技術，希望將色域映對技術應用於此領域中。本研究以相同品牌不同尺寸之兩台液晶顯示器為研究對象，其兩者之色域與特性曲線皆不相同，所呈現的色彩亦不同，研究其色彩校正之問題。本論文建立了一：顯示器量測與調校平台二：色域對映平台並在色域對映的技術中，以等亮度色域邊界理論為基礎，提出快速的顯示器色域立體繪製方法。此外本論文亦就顯示系統參考白點亮度與色域體積之最佳化做研究。最後以所建立之色域對映平台進行兩螢幕色域對映的實驗。實驗結果顯示，在顯示器之間的映對均以剪裁方式得到較好的結果 Recently, information display system echnologies have encountered a big leap. Companies are changing their emphasis from how to improve manufactory specification process to the basic demand of display system, satisfying human eyes. Color is one of the most important attribute to this goal. Color inconsistent of the display product lines are one of the serious problems that most manufactures have faced in common. For solving this problem, color appearance calibration technique between similar or dissimilar display system is inevitable. We introduced you a complete research discussion for display color calibration by using gamma curve adjustment and gamut mapping techniques in this thesis. Platforms of the experiment are constructed on two LCD monitors which are in same brand but different size. Hoping to find the way makes the color appearance to “perceive” equally. In this thesis we introduced you both 1. Display gamma curve measurement and adjustment platform 2. Display gamut mapping platform with fast GBD algorithms to achieve the goal.
