Indlela ezibona ngayo
inyosi ibona kanjani umhlaba?
Ibona imihlahlandlela ye-UV yezimbali, ayiboni obomvu
Inyosi ifunda imbali njengeshadi lokuhlala kunesithombe. Umhlaba wayo wakhiwe nge-ultraviolet, okuluhlaza okwesibhakabhaka nokuluhlaza, ngaphandle kwe-receptor ebomvu nhlobo, ngakho i-poppy ebomvu ibukeka icishe imnyama. Izimbali eziningi ezimhlophe, ngokuphambene, zembula ama-bullseye e-ultraviolet akhanyayo aqondisa inyosi ngqo kuju. Isithombe siluhlaza, kodwa yiso kanye isithombe umqoqi asidingayo.
Bona ngamehlo azo
Umuntu ≈ 60 cpd (20/10)
Ukubona kuka-inyosi kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-0.25 ngedigri (20/2400), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-280°.
inyosi ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-0.25 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-240 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 inyosi engayibona?
Ukubona umbala we-UV-oluhlaza sasibhakabhaka-oluhlaza. Obomvu ubukeka umnyama noma umnyama; izimbali zembula izinhloso ze-UV ezifihliwe.
Ama-photoreceptor
I-Trichromatic eshiyele ku-UV (ayinaso iseli lombala obomvu), amehlo axutshiwe
Iziqongo zokuzwela kwama-cone
- UV344 nm
- Oluhlaza sasibhakabhaka436 nm
- Oluhlaza544 nm
inyosi ibona kanjani ebumnyameni?
Isebenza emini; imbi ekukhanyeni okuncane.
Ukubona kuka-inyosi kuqhathaniswa kanjani nokomuntu?
Imininingwane yendawo yenyosi, cishe ku-20/2400, iluvivi kakhulu kune-20/20 yakho, futhi iyimpumputhe kokubomvu. Ekubuyeni ibona i-ultraviolet ongeke uyibone, futhi amehlo ayo avuselela ngokushesha, cishe izikhathi ezingu-200 ngomzuzwana, kangangokuthi ukunyakaza okufunda njengoluvivi kusakazekile ngokusobala enyosini.
Yini eyisipesheli ngokubona kuka-inyosi?
- Ibona iziqondiso zoju ku-ultraviolet
- Ayiboni obomvu
- Ukuhlanganisa kokuqwayiza ~200 Hz: ibona ukunyakaza okusheshayo kancane kancane

Khomba ikhamera yakho kunoma yini bese ubuka umhlaba uguquka ube ukubona kwalesi silwane ngesikhathi sangempela.
