There’s an interesting discussion going on over at the DPReview forums regarding how the human eye compares to the technology we have in digital cameras.

Here are some of the findings that were compiled from various sources on the web:

• Sensor size: 22mm in diameter
• Resolution: 576 megapixels
• Sensitivity: 1 – 800 ISO
• Focal length: 22mm – 35mm
• Aperture: f/2.1 – f/8.3

Another interesting idea that came up was the possibility of using the human eye as the lens and sensor for future imaging devices:

Maybe future “cameras” will actually link to your eyes – since the eyeball is such a great lens, who knows? Getting signal from the eye is the trick – would require a surgical implant or a means of reading brainwaves. Maybe that’s 200 years out – similar time [frame] the Mayo clinic is talking about for correcting double/triple vision.

Perhaps in the future we’ll all be documenting our lives at 576 megapixels through our eyes and ears, and storing the photos and videos on petabyte external hard drives at home.

What do you think of this discussion? Is there anything that jumps out at you as being wrong, or do you agree with the comparison for the most part?
