The compound eyes of insects are composed of tens of millions of ommatidia. Due to the mutual inhibition between the ommatidia, the eyes have the function of highlighting the frame of the image and increasing the clarity. People imitated the honeycomb structure of the small eyes in the abdomen of flies and made a "fly eye camera" for scientific research. It can take 1,329 photos at a time, with a resolution of 4,000 lines.
