If you were to compare eyesight to television, how many pixels would a person's eye contain?

Question

I was just wondering whether a person's eyesight has a 'native resolution' similar to a tv, as there will eventually be a level of detail achieved by a high resolution on a tv screen that will allow a tv to create the longed for 'looking out of a window' effect that most TV manufacturers dream of achieving one day.

Thanks

And so, because eventually noone will be able to see a difference between what's on a TV and whats real, I am wondering whether a person's eye's, like a tv, has a reslution/pixel count/eye cell count similar to that of a TV.

Answer 1

The human eye is analog.
There is more to a picture than mere pixels. There is color depth (levels of gray) and then there is color gamut (range of colors you can reproduce). Finally, it is very difficult with a 2D display to create 3 dimensions. So, long away to go.

Answer 2

I think you're onto something. The human eye bases "vision resolution" on a series of "cones" and "rods". You may wish to search a website that'll telll you how many of them are in each eye, therefore, speaking roughly, you have the resolution. It may be possible in the future to make a "TV set" an extremely high resolution, more than the eye can pick up! But then again you could maybe increase the amount of rods and cones in the eye well into the future!

Answer 3

Did you know that the picture on the tv is actually upside down and it flikers at a rate of knots of which the human eye can't see it's the retiner in the eye that makes you see the picture the right way up. Strange but true............
