Indlela ezibona ngayo
imvu ibona kanjani umhlaba?
Iso elibanzi lomhlambi elibuka ukunyakaza
Njengembuzi, imvu ibuka umhlaba ngezinhlamvu zamehlo ezivundlile, ezimise okwesikhala ezelula umbono wayo ocacile ibe yibhande elibanzi kuwo wonke umumo. Iyinyamazane edliwayo, ngakho amehlo ayo aqoka umbono obanzi, obamba ukunyakaza kunemininingwane ecacile, futhi ibona okuluhlaza okwesibhakabhaka nokusaphuzi okuphuphile kwe-dichromat. Umhlambi ungaqapha cishe kuzo zonke izinkombandlela kanye kanye.
Bona ngamehlo azo
Umuntu ≈ 60 cpd (20/10)
Ukubona kuka-imvu kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-7 ngedigri (20/86 (est.)), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-300°.
imvu ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-7 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-9 ukuze ibone imininingwane oyibonayo. Isimo sakho nokunyakaza kwakho kufika kucacile; ukubukeka kobuso bakho akufiki.
Ukuqhathanisa imibala
How each colour shifts when seen through this animal's eyes, using the same colour model as the app. Tones a screen can't emit (such as ultraviolet) are shown as an approximation.
Yimiphi imibala imvu engayibona?
I-dichromacy eluhlaza sasibhakabhaka-phuzi; ukuhlukanisa obomvu okubi.
Ama-photoreceptor
I-Dichromat (izinhlobo ezi-2 zamaseli e-cone)
Iziqongo zokuzwela kwama-cone
- S (oluhlaza sasibhakabhaka)450 nm
- L (oluhlaza)553 nm
imvu ibona kanjani ebumnyameni?
Okuhle; i-tapetum lucidum isiza ukudla ekuseni nasekushoneni kwelanga.
Ukubona kuka-imvu kuqhathaniswa kanjani nokomuntu?
Imininingwane yemvu icishe ibe ngu-20/86 kune-20/20 yakho futhi ibona imibala emibili kunemithathu. Inkambu yayo ecishe ibanzi, esizwa ungqimba olukhulisa ukukhanya kokusa nokuhlwa, iyawudlula kakhulu umbono wakho obheke phambili.
Yini eyisipesheli ngokubona kuka-imvu?
- Isikhala esivundlile
- Inkambu ecishe ijikeleze
- Izwela ukunyakaza
