လူ႔ မ်က္လံုး Megapixel
Monday, June 17, 2013
လူတစ္ဦးရဲ ႔ မ်က္လံုးမွာ 576 megapixels ရွိပါတယ္။ iPhone 5 မွာ 8 megapixel ဆုိေတာ့ မ်က္လံုးက ၇၂ ဆေတင္ သာပါတယ္။
မ်က္လံုးနဲ႔ ပက္သက္လို႔ သူ႔ရဲ ႔ ျမင္ႏိုင္စြမ္း အေသးစိတ္ Specification ကေတာ့ ေအာက္ပါ အတိုင္း ျဖစ္ပါတယ္။
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
ISO : 1 - 800 equivalent
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
