What resolution is human vision?

[redspear]

Most people here are right. How detailed we see something depends on the distanced this is also true of Cameras the farther something is the lesser the detail. It is all about the angular diamater also known as how large something appears.

In a picture or video a pixel represents so many arc seconds that arc second could represent 1000th of an inch 2 feet 8 miles or 5 light years depending on the distance hence when you take a picture of the moon it appears small upping the rez allows for greater detail because you get smaller arc seconds.

The eye does the same thing. It can even suffer from things like chroma abberations blurring when the aperture(iris) gets to small but only if you get screwed up the eye switches from cones to rods.

You have more rods than coens in your eyes. The cones see color the rods see B & W. The brain then takes information from these sources and compiles it in the brain elimination duplicative information and adjusting(Your eyes have to cameras and while you see only one monitor in front of you they actually have a different angle you brain throughs out junk so that you only recognize one and thus can function

Oer eyes have approximately 5-7 million cones and 100-120 million rods. As you can see the resolution at which the eye can see is very edependent on the situation and how much light there is. I am not sure but I do think both are active at the same time and that the brain takes info from the cones and uses it to upscale the B&W infor the rods to color. If that sounds bizarre to you think abotu this when you take a picture with digtal camera or a video doesn't matter. The camera DOES not record in color. It records in monochrome 3 times. Each of the sperate images contain pixels and each of these images contain pixel information that can be 0-255 or 8 bit but when you apply all three you know have 3 sets of 0-255 that correspond to the same image the computer than takes these monochrome images and translate them to color and voila you have a 24 bit image.

So to answer your question around 110 megapixels but all the way up to 125 megapixels but ny images you see rapidly lose their detail because of angular diameter so a TV with even half that rez woudl still be over kill for resolution.


I hope this helps a little.
