The 120Mpixel figure for the human eye is completly phony. The eye has the ability to resolve very fine detail, but over a very limited field of view. The 120 Mp number seems to be arived at by taking the finest detail that the eye can resolve and extending that over the entire FOV of the eye. That is not even close to the way the eye works. In addition, the eye has a blind spot where the nerve bundle passes. Contrary to what seems to be in just about every book, the eye is very bad model for a camera.
