The fly is presented as an example for visual information processing. It is shown that "simple" compound eyes of insects possess functions which are comparable with those of the complex lens eyes in higher vertebrates. The problems of coding of contrast, colour and polarized light are discussed. Temporal resolution of the visual system is characterized in terms of a transfer function and this reveals differences to vertebrates, but only in respect to the higher fusion frequency. Spatial coding of light informations is not very well understood but there is evidence for lateral inhibitory interactions, especially in the lamina. Thus we can conclude that the retina presents all premises at least for a simple shape and motion analysis in the fly's tiny brain.
苍蝇被作为视觉信息处理的一个例子。研究表明，昆虫的“简单”复眼具有与高等脊椎动物复杂的晶状体眼相当的功能。文中讨论了对比度、颜色和偏振光的编码问题。视觉系统的时间分辨率通过传递函数来表征，这揭示了与脊椎动物的差异，但仅在更高的融合频率方面。光信息的空间编码尚未得到很好的理解，但有证据表明存在侧向抑制相互作用，尤其是在神经纤维层。因此我们可以得出结论，视网膜至少为苍蝇微小的大脑中进行简单的形状和运动分析提供了所有前提条件。
