the big difference between modern cameras and eyes is that a huge amount of neural processing is done in the retina of the eye. There aren't any cameras (that I know of) that compute such sophisticaed levels of processing (edge detecting, contrast detecting, motion detecting) within the sensor package.
There are CMOS sensors with in-array edge detection. More flexibly, all optical mice have integrated sensors that do motion processing in the same package if not the same die.
