Equiluminance ratios for red/green, red/blue and green/blue sine-wave gratings were determined by using a minimum-motion heterochromatic matching technique that permitted reliable settings at temporal frequencies as low as 0.5 Hz. The red/green equiluminance ratio was influenced by temporal but not spatial frequency, the green/blue ratio was influenced by spatial but not temporal frequency, and the red/blue ratio was influenced by both. After bleaching of the blue-sensitive cones, there was no change in equiluminance ratios, indicating no contribution of the blue-sensitive cones to the luminance channel even at low temporal and spatial frequencies. The inhomogeneity of yellow pigmentation within the macular region was identified as the source of the spatial-frequency effect on the blue/green ratio.
通过使用一种最小运动异色匹配技术来确定红色/绿色、红色/蓝色和绿色/蓝色正弦波光栅的等亮度比，该技术允许在低至0.5赫兹的时间频率下进行可靠的设置。红色/绿色等亮度比受时间频率而非空间频率的影响，绿色/蓝色比受空间频率而非时间频率的影响，而红色/蓝色比受两者的影响。在蓝色敏感视锥细胞漂白后，等亮度比没有变化，这表明即使在低时间和空间频率下，蓝色敏感视锥细胞对亮度通道也没有贡献。黄斑区域内黄色色素沉着的不均匀性被确定为对蓝色/绿色比产生空间频率效应的来源。
