(Edit update: by "detectable" I mean theoretically detectable by a really good camera and software. In other words, it seems you are arguing the tech is impossible even theoretically due to some aspect of biology. Am I following you correctly there? Thanks)
Your field of vision (and focus) is much bigger than 1 degree, so any part of the image that you are "looking at" is something the brain is doing to the image as post processing, not something your eyeball is doing.
