摘要

一般来说,人类的视觉系统试图忽略光照,这样它就可以提取表面形状和反射特性,而不受周围环境的影响。这阐明了视觉的目的,即快速识别和分类物体,以便高级大脑可以寻找机会,避免可能存在的障碍和危险。低级的视觉处理是生存的根本,是动物数亿年进化的产物。可以说,视觉的作用是规避光照。

Dynamic range and visual perception
Broadly speaking, the human visual system attempts to discount illumination so it can extract surface shapes and reflectance characteristics, independent of one's surroundings. This elucidates the purpose of vision, to quickly identify and categorize objects so the higher brain can seek opportunities and avoid obstacles and dangers that may be present. Low-level visual processing lies at the very root of survival, and is the product of hundreds of millions of years of animal evolution. It could be said that vision works to circumvent lighting.
