If your eye(s) was a camera how many megapixels would it be?

Question

like my camera in my phone is 1.3 mega pixels,
and my camera is 7.0 mega pixels what about eyes?

Answer 1

The human eye does not work in the same way as a camera, so the comparison is not strictly fair.

The human eye scans a scene to build up a picture. Based on the eyes acquity, this means it has a resolution for a scene 90 degrees by 90 degrees of around 324 million pixels.

In fact, the eye can scan scenes larger than this (to the perphery of vision is closer to 130 or so degrees), but your working field of view is more like this figure.

Answer 2

"The ordinary human retina has 5 million cone receptors on it. Since the cones are liable for color imaginative and prescient, you could consider that this equates to a 5 megapixel equivilant for the human eye. But there also are 100 million rods that observe monochrome distinction, which performs an major position within the sharpness of the snapshot you notice. And even this 105MP is an underestimate seeing that the attention isn't a nonetheless digicam. You have 2 eyes (no kidding!) and so they constantly flick round to hide a far higher field than your area of view and the composite snapshot is assembled within the mind - now not in contrast to sewing in combination a breathtaking image. In well gentle, you'll distinguish 2 quality strains if they're seperate through a minimum of zero.6 arc-mins (zero.01.Degrees). This offers an equivilant pixel measurement of zero.three arc-mins. If you are taking a conservative a hundred and twenty levels as your horizontal area of view and 60 levels within the vertical aircraft, this interprets to ... 576 megapixels of to be had snapshot information."

Answer 3

Good question, as there are a finite number of rods and cones in the eye (equivalent to the CCDs in digital cameras). However the main difference is our eyes are analog, not digital, and so do not suffer from the same limitations that "megapixel" cameras do. Otherwise we'd suffer from the same pixelated distortions that digital photos do!

So.. mathematically.. we have infinite pixel resolution, though obviously there are finite limits on our vision in terms of focus and range etc.
