我们研究了贡献的光学和感光特性，以及受体池偏心依赖的空间视觉的变化，通过比较理想的观察者与人类观察者的性能。 我们测量对比敏感度功能在人类观察者和计算这样的功能在理想的观察者视网膜偏心0-40度。 人类和理想的性能在各种任务的比较表明，许多方面的变化，在空间视觉与偏心率可以理解从分析的歧视信息，可在视网膜神经节细胞。
We examined the contribution of optical and photoreceptor properties as well as receptor pooling to eccentricity-dependent variations in spatial vision by comparing the performance of ideal observers with that of human observers. We measured contrast sensitivity functions in human observers and calculated such functions in ideal observers for retinal eccentricities of 0-40 deg. Comparisons of human and ideal performance in a variety of tasks reveal that many aspects of the variation in spatial vision with eccentricity can be understood from an analysis of the discrimination information available at the retinal ganglion cells.
