Researchers at the University of California found that the human eye has about 10~ 12 output "channels", and each "channel" sends information to the brain and then forms an image. People's retina will present groups of images, which are the result of communication between cells in the retina. They invented a computer micro-integrated circuit called "cellular neural network", which can be used for image processing similar to retinal function. This is the basic principle of inventing bionic electronic eyes.
Researchers are beginning to improve computer microchips from a biological point of view, making them more and more like the retina of mammals. But in order to make bionic electronic eyes really replace human eyes, scientists must also solve the mystery of how to connect computer micro-integrated circuits with complex human brain circulation systems.
