KANSEI Evaluation of Color Images Presented in Color Gamuts with Different Blue Primaries

摘要

To investigate the best blue primary for color display from KANSEI-evaluation point of view, evaluation experiment using Semantic Differential method was carried out using four different blue primaries of 430nm, 450nm, 470nm, and 480nm at 60cd/m~2. The same experiment was done for 450nm, 470nm, and 480nm at 170cd/m~2. In the results of 4 primaries, 450nm and 470nm blue primaries show the best, 430nm is the next, and 480nm blue primary shows the worst performance. In the results of 3 primaries, 470nm shows the highest scores for bluish test images. Results are compared with color naming data in the entire chromaticity diagram.
