光源色と物体色の再現に適した3原色ディスプレイの色域に関する研究

摘要

本研究では，光源色と物体色を再現する上で適した3原色ディスプレイの色域について検討を行った．先ず，モデルに基づいて計算により求めた光源色に対して色差が最小になる3つの原色点を導出した．同時に，導出した色域に，ほぼ全ての代表的な物体色と，BT.709の色域の色が含まれるようにした．さらに，分光視感効率の観点から実現可能な原色を検討した．%We studied color gamut of a three primary display which is optimum for reproducing light-source colors and object colors. Color gamut of three primaries was derived where color difference between reproduced and calculated light-source colors is minimum. The light-source colors were obtained by calculation based on a model. At the same time, almost all typical object colors and those in the gamut of BT.709 were considered to be included in the derived color gamut. In addition, the primaries were selected by taking into consideration spectral luminous efficiency.
