这项研究工作的目标是在大范围内生成高质量的色彩对比敏感度 (CCS) 数据,特别是在 5 个色心(例如白色、红色、黄色、绿色和蓝色)周围的低空间频率下。使用强制选择楼梯进行了实验 方法研究不同空间频率下不同颜色变化方向的可见色差阈值。使用不同空间频率下的最小显着差异(JND)椭圆来表示数据。
The goal of this research work is to generate high quality chromatic contrast sensitivity (CCS) data over a large range, especially at low spatial frequencies surrounding 5 colour centres, e.g.white, red, yellow, green and blue. An experiment was carried out using forced-choice stair-case method to investigate the visible colour difference thresholds in different colour changing directions at different spatial frequencies. The just noticeable difference (JND) ellipses at different spatial frequencies were used to represent the data.
