在欧洲人群中，大约每12名男性中就有一名受遗传性色觉缺陷的影响。人们主要研究它在原始觅食中的作用，但也研究它在探测脸红和破坏伪装方面的作用。然而，这些具体任务与现实世界中的愿景之间并没有明显的关系。这里的目的是通过计算估计观察者可以获得的关于自然场景中有色表面的信息来量化色觉缺陷的影响。对于具有代表性的50和100个高光谱图像的独立集合，红绿色视觉缺陷的估计信息量仅比正常三原色少一点。比色分析揭示了场景内大的亮度变化、小的红绿变化以及不同颜色表面的不均匀频率的重要性。虽然红绿色视觉缺陷在某些任务中会带来挑战，但它对从自然环境中获取信息的影响要小得多。辨别任务不能预测色觉缺陷对真实世界的影响在自然场景中，亮度而不是色度主导了变化，颜色表面的小色域和不均匀的频率限制了可用的信息，红绿色视觉缺陷在自然科学、物理、生物科学中几乎没有不利影响
Inherited color vision deficiency affects red-green discrimination in about one in twelve men from European populations. Its effects have been studied mainly in primitive foraging but also in detecting blushing and breaking camouflage. Yet there is no obvious relationship between these specific tasks and vision in the real world. The aim here was to quantify the impact of color vision deficiency by estimating computationally the information available to observers about colored surfaces in natural scenes. With representative independent sets of 50 and 100 hyperspectral images, estimated information was found to be only a little less in red-green color vision deficiency than in normal trichromacy. Colorimetric analyses revealed the importance of large lightness variations within scenes, small redness-greenness variations, and uneven frequencies of different colored surfaces. While red-green color vision deficiency poses challenges in some tasks, it has much less effect on gaining information from natural environments. Discrimination tasks do not predict real-world impact of color vision deficiency Lightness not chromaticity dominates variation in natural scenes Small gamut and uneven frequencies of colored surfaces limit information available Red-green color deficient vision is little disadvantaged in natural environments Natural sciences; Physics; Biological sciences
