RGB Color Mixing Model on Large Display Units Considering Human Color Vision
This paper describes an analytical model for the additive color mixing process of RGB considering both the pixel structure and human color vision. The proposal treats additive color mixing as a following phenomenon; RGB signals on a display unit are spread spatially by human color vision, and overlap with each other according to the pixel structures. Therefore, the colors perceived can be explained as the multiplication of the spatial frequency array of the pixel structures, and the spatial frequency properties of human color vision. Secondly, the color mixing process is discussed using this proposal with a blue and green striped pattern that has the same band widths and pitches. Finally, to verify UK validity of this proposal, subjective evaluation experiments using B-G striped patterns were conducted. In the experiments, subjects approached the sample patterns from where the sample was perceived as cyan. The visual distances when the component colors were identified were measured. As experimental results, the relationship of visual distances compared well with the analytical results. Therefore, UK proposed model is effective for designing display units considering the geometric information regarding RGB pixel arrays and visual distances.
