Leyo khamera eshisayo ingabona kude kangakanani?
Ukuze uqonde kude kangakanani aikhamera eshisayo(nomaikhamera ye-infrared) ungabona, okokuqala udinga ukwazi ukuthi into ofuna ukuyibona inkulu kangakanani.
Ngaphandle kwalokho, liyini izinga "lokubona" olichazayo kahle?
Ngokuvamile, "ukubona" kuzohlukana kube amazinga amaningana:
1. Ibanga letiyori eliphakeme kakhulu: inqobo nje uma kunephikseli eyodwa ku- isithombe esishisayo isikrini ukuze sibonise into, kodwa kulokhu ngeke kube nesilinganiso esinembile sokushisa
2. Ibanga lokulinganisa izinga lokushisa okucatshangwayo: uma into eqondiwe ukuze ikwazi ukukala izinga lokushisa elinembile, ngokuvamile idinga okungenani amaphikseli angu-3 esitshina aboniswa kudivayisi, ngakho-ke ibanga lokulinganisa izinga lokushisa elingokomqondo liyinani into engakwazi ukuliphonsa 3. amaphikselion ikhamera yesithombe esishisayo.
3. Ukubhekwa kuphela, akukho silinganiso sokushisa, kodwa okubonakalayo, khona-ke lokhu kudinga indlela ebizwa ngokuthi i-Johnson Criterion.
Lo mbandela ohlanganisa:
(1) Izinhlaka ezingaqondakali ziyabonakala
(2) amajamo ayabonakala
(3) imininingwane iyabonakala
Ibanga eliphezulu lokucabanga = inani lamaphikseli aqondile × usayizi oqondiwe (ngamamitha) × 1000
Inkambu yokubuka eqondile × 17.45
or
Inani lamaphikseli avundlile × usayizi oqondiwe (ngamamitha) × 1000
Indawo yokubuka evundlile × 17.45
