Xa kuthengwa kwiKhamera, Kubalulekile Ukukwazi Ukwahluka
Amaccorders amaninzi (kunye nee-smartphones) ziquka uhlobo oluthile lwe-teknoloji yokuzinza (IS) ubuchwepheshe bokunciphisa ukugqithiswa kwevidiyo ephumela kwizandla ezithintekayo okanye ukunyakaza komzimba. Into eyona nto ibalulekileyo i-tripod kodwa kukho iindlela ezimbini zobuchwephesha ezithatha inyathelo elongezelelweyo: optical and digital.
Ukuqiniswa komfanekiso kubalulekile kubo bonke abakwa-camcorders, kodwa kubaluleke kakhulu kulabo abaye bahamba ngokukhawuleza ukuvavanya okanye ii- lens zoom zoom . Xa i- lensi isondeza ukuya ekukhuliseni kwayo, iya kuba yinkxalabo enkulu kunokuba yinto ehamba phambili.
Abanye abakhiqizi bafaka igama lomtsalane kwi-teknoloji yokuzinzisa imifanekiso. U-Sony uyayibamba iSteadyShot ngelixa i-Panasonic ibiza i- Mega OIS kunye ne-Pentax Shake yokunciphisa . Ngamnye unemiba yabo kodwa benza umsebenzi ofanayo.
Kwimeko nayiphi na imeko, kufuneka uhlale ukhangelelanisa kwi-jargon kwaye ukhangele kwiinkcukacha. Kufuneka ibonise ukuba i-camcorder enikwe i-optical okanye i-digital stabilization okanye zombini.
UkuLungiswa koMzobo
Ukuqiniswa komfanekiso we-Optical (OIS) yindlela efanelekileyo kakhulu yokuzinza imifanekiso. Ama-Camcorders ene-static image stabilization abonisa ama-gyro-sensors amancinci ngaphakathi kwilensi ekukhawuleza ukutshintsha iziqwenga zeglasi yelenjini kwisilingi sokumisa phambi kokuba umfanekiso uguqulwe kwifomu yedijithali.
Iteknoloji yokuzinza imifanekiso ithathwa njengento ebonakalayo xa ibonisa into ehambayo ngaphakathi kwilensi.
Abanye abakhiqizi bekhampasi bavumela ukuba uguqule kwaye uvale imifanekiso ye-optical, okanye udibanise iimodi ezininzi ukuhlawulela iintlobo ezahlukeneyo zokunyakaza kwekhamera (nokuba yimibala okanye i-horizontal).
UkuLungiswa koMfanekiso weDiagram
Ngokungafani neenkqubo ze-optical, ukugcinwa komfanekiso wedijithali (ekwabizwa ngokuba yi-electronic image stabilization, okanye i-EIS) isebenzisa iteknoloji yesofthiwe ukwenzela ukunciphisa impembelelo yezandla ezizenzekelayo kwividiyo. Ngokuxhomekeke kumzekelo, oku kuya kwenziwa ngeendlela ezininzi.
Abanye abakwa-camcorders baya kubala umphumo wokunyakaza komzimba wakho kwaye basebenzise loo datha ukulungelelanisa iipikseli ezinjani kwi- sensor image image . Isebenzisa iipekseli ukusuka ngaphaya kwefowuni ebonakalayo njengendlela yokunyakaza okuhamba phambili ukugqithisa phezu kwesakhelo soguquko ngesakhelo.
Kubathengi bekhamera zedijithali, i-digital image stabilization ngokuqhelekileyo isebenze ngaphantsi kwe-optical stabilization. Ngenxa yokuba, ihlawulela ukujonga ngokukhawuleza xa i-camcorder ithi ikwazi "ukuzinza imifanekiso." Kungenzeka kube yintlobo yedijithali kuphela.
Kukho neeprogram zeproofthiwe ezingasebenzisa ukuhlunga uhlalutyo kwividiyo nangemva kokuba kuthathwe, ngokulandelela ukunyakaza kwepikelli nokulungiswa kwesakhelo. Nangona kunjalo, oku kubangela ukuba imifanekiso encinci egciniweyo ngenxa yesakhelo esincitshisiwe okanye ukugxilwa kwezinto ezongezelelweyo ukuzalisa imiphetho elahlekileyo.
Olunye Udidi lwezobuchwepheshe bokuzinza
Nangona i-optical and digital stabilization ixhaphake kakhulu, ezinye ubuchwepheshe buzama ukulungisa ividiyo engaqinisekanga nayo.
Ngokomzekelo, kukho iinkqubo zangaphandle ezizinzisa umzimba wonke wekhamera endaweni yokuba uyenze ngaphakathi kwekhamera yekhamera. Indlela oku kusebenza ngayo ngokuba ne-gyroscope efakwe kumzimba wekhamera ukwenza uzinzo. Ezi zidla ngokubonakala xa zifotshwa kwizithuthi ezihambayo.
Enye i-CCD yokudlulisa i-CCD (i-OTCCD), esetyenziswa kwi-astronomy ukuzinzisa imifanekiso.
