Human Eye Specifications (typical):
- Sensor (Retina) : 22mm diameter x 0.5mm thick (section); 10 layers
- Resolution : 576MP equiv.
- Visual Acuity : ~ 74 MP (Megapixels) (printed) to show detail at the limits of human visual acuity
- Data Rate : 500,000 bits per second without colour or around 600,000 bits per second including colour.
- Lens : 2 lenses - 16mm & 24mm diameter
- Dynamic Range - Static : contrast ratio of around 100:1 (about 6 1/2 f-stops) (4 seconds)
- Dynamic Range - Dynamic : contrast ratio of about 1,000,000:1 (about 20 f-stops) (30 minutes)
- Focal Length : ~ 3.2mm - (~ 22mm 35mm equiv)
- Aperture : f2.1 - f8.3 (f3.5 dark-adapted is claimed by the astronomical community)
- FOV Field of View : 95° Out, 75° Down, 60° In, 60° Up
- Color Space - 3D (non-linear) RGB
- Color Sensitivity : 10,000,000 (ten million)
- Color Range : 380 to 740 nm
- White Balance : Automatic (constant perceived color under different lighting)
- Refresh Rate : foveal vision (high-quality telescopic) - 3-4fps; peripheral vision (very inaccurate) - up to 90fps
Obviously compiling this creates some very big assumptions - many of these are interrelated to the brain's processing of the eye's signals. I am sure that while the above statistics are factual, presenting them as a direct apples-for-apples correlation to common camera specifications is probably fraught with inconsistencies. So bear in mind that I did this just for fun!
