.... what is the resolution of a human eye?
Can they be equated to eachother? i.e. Can an eye be given a "megapixel" value?

What you have to consider is the total amount of rods and cones on the retina, as there are the light sensitve receptors that give us visual information.
Computer Monitors (standard 1024x768) have a higher resolution than the human eye, and most TVs and Cinema screen have a higher refresh rate too.
However, we tend not to keep our eyes still and we instead flit our eyes around to gather more information about the scene. Given that we have a 90deg range of eye tilting we can see up to a 324 megapixel equivalent image.

As the eye operates in 'rods' and 'cones'. ie. colour receptors and light sensors it breaks down as follows:
There are around 6 to 7 million CONES. 64% RED, 32% GREEN and 2% BLUE receptors.
BUT, there are about 120 MILLION RODS. These do not respond to colours, only light intensity.
So we have a colour resolution of 6 or 7M pixels but a Black & White resolution of upto 120 M pixels.
Hope that helps.

decision is the DPI or dots in line with inch on the demonstrate screen. The greater DPI the greater you are able to enhance the print. In digital cameras, that is measured via megapixels (a pixel is one million dot). Technically the better the pixels, the better the call. established digicam use demands greater or less 7-12 megapixels for crisp sharp photos. once you have destructive decision, the colors fade and the lines get fuzy. Your photograph colour is dependant not only on the call, yet on the visual demonstrate unit, computing device and application you employ to reproduce it. It is likewise stimulated via the print technique, inks and chemical compounds.

It is different. The digital imaging need to store the digital data inti pixel by pixel to have a picture. But Human eye work as fine as lens or it can said analog data. But Human eyes depend on the eyes condition (health).

I suppose you could count the number of cells on a retina - that would equate to the pixel number of a camera. But we see in 3D with 2 cameras! Beat that!

You notice how many pixels you camera has when you make an enlargement. A 6M pixel camera will make an A4 enlargement before your eye can see the dots in it.

As strange as it may seem the humune eye is 8 megapixels and inside your head is a 1GB storage card!

No. the operative word there is digital. Our eyes work on an analogue principle so therefore we do not have pixels as such.
