Anyone know of an studies that describe what is the high end of what the human eye can see in terms of pixel resolution and dot pitch?

There was a very good article in Photonics Spectra describing the process of Colorimetry in the brain.
If Neuroscientists can achieve the level of technical evulation as contained in the Spectra article,
they should be able to formulate what resolution the eye can see.

Thanks in advance

Well thank you Husky but I also wondering what is the maximum pixel resolution that the human eye can discern?
That will certainly be a concern with computer monitors and HDTV as pixels become infinitely smaller with Nanophotonics and such. Maybe HDTV will reach 4K 4096 x 3002 as cable increases in bandwidth Though will resolution be able to go on forever in the future?

Thanks again.

Commercial printers print at 300 dpi because that’s the resolution of the human eye viewing at normal reading distance.

Most of us would see the difference between lineart at 2400 dpi and the same thing converted to a bitmap at 300 dpi… 🙂

But the clincher is how increasing the "line screen" from 150 to 200 produces a slightly wider CMYK gamut, as long as the blanket on the press is able to "hold" the super- fine halftone dots.

I have an example of this I show to other colleagues on occasion, the same file printed at 150 LPI and at 200 LPI.

I did a quick experiment. I put a single black pixel on a white field on my LCD monitor. The resolution is 1280×1024, and the monitor is 33.8cm wide, so the pixel is a .264mm square. I can not see it beyond 2m away.

One other thing was demonstrated by my experiment too. At, 2m, I could see the dot only by looking _straight_ at it. Resolution is much higher at the center of the fovea.

By the way, my vision is not perfect, but I’m wearing my glasses 😉
