22/05/20Iikhamera ezininzi zenzululwazi zisebenzisa isivamvo sokupholisa ukunciphisa impembelelo yobushushu obuxhomekeke kubushushu 'ingxolo yangoku emnyama'[ikhonkco] kunye neepixels ezishushu. Ezinye iikhamera zibonelela ngeendlela ezininzi zokupholisa zendlela ubushushu obugqithileyo obususwa ngayo, kanti kwezinye iikhamera kunye nezicelo zomfanekiso, akukho kupholisa kuyadingeka.
Isensom yekhamera ngokwayo ipholiswa rhoqo ukuya kumaqondo obushushu angaphantsi kwe-zero ngesixhobo sePeltier, esihambisa ubushushu kwinkqubo yokususa ubushushu yekhamera. Ukupholisa 'Umoya' okanye 'Umoya onyanzelekileyo' yeyona ndlela ixhaphakileyo yokususa ubushushu, apho ifeni isebenzisa ukuhamba komoya ukutshintshisa obu bushushu bugqithileyo nomoya ojikeleze. Kungenjalo, ezinye iikhamera zikwabonelela ngesakhono sokusebenzisa inkqubo yokuhambisa ulwelo ukususa ubushushu kwindawo yokugcina amanzi okanye kwibhafu epholileyo. Oku kunokubonelela ngeenzuzo kwezinye iimeko, ngokutshintshiselana ngokusebenzisekayo kunye nokuqwalaselwa kweendleko.
Ngaba ndifuna ukupholisa ulwelo?
Kwiikhamera ezipholileyo, ukupholisa komoya yeyona ndlela ifanelekileyo yokubonelela ukuhamba komoya okwaneleyo kunokwenzeka malunga nekhamera, kwaye iqondo lobushushu legumbi aliphezulu kakhulu. Oku kufuna akukho malungu ongezelelweyo okanye ufakelo, kwaye akukho mngcipheko wokuchitheka okanye ukuvuza. Kodwa kukho iimeko ezimbini eziphambili apho ukupholisa ulwelo kunokuba yimfuneko.
Okokuqala, kwezinye iikhamera, ukupholisa ulwelo kunokuxhasa iqondo lobushushu elisezantsi lesensor, ethi ke ibonelele ngengxolo esezantsi emnyama yangoku. Ukuba ixesha elide lokuvezwa kwamashumi emizuzwana ukuya kwimizuzu efunekayo ngezi khamera, ingxolo encitshisiweyo inokubonelela ngomlinganiselo obalulekileyo wesignali ukuya kwingxolo kunye nokuphuculwa komgangatho womfanekiso.
Okwesibini, ngelixa zonke iinzame zenziwe ngexesha lokwenziwa ukunciphisa ukungcangcazela kwifeni yangaphakathi yekhamera, ngamanye amaxesha kwizixhobo ezibuthathaka kakhulu oku kunokuba yingxaki. Kule meko, ukupholisa ulwelo kwenza ufakelo lwekhamera olungangcangcazeliyo, kunye nenkqubo yokujikeleza kolwelo emva koko ikwazi ukwahlulwa kwisixhobo esibuthathaka.
