I-Optical Image Stabilization (OIS) bubuchwephesha obutshintshe ihlabathi lokufota kunye nokuhlolwa kweCCTV.

Ukusukela ngo-2021, ukuzinza komfanekiso obonakalayo kuye kwavela ngokuthe ngcembe ekubekeni iliso kukhuseleko, kwaye kunotyekelo lokuthatha indawo ye-lens yesiqhelo ye-non-optical image stabilization lens.Kuba yenza ukuba kuthathwe imifanekiso ebukhali necacileyo naphantsi kweemeko eziguquguqukayo, iyenza into ebalulekileyo kwiikhamera zanamhlanje. kunye neekhamera zeCCTV. Kodwa isebenza njani i-OIS? Kweli nqaku, siza kuphonononga iteknoloji emva kwe-OIS nge-lens - inkqubo esekelwe.

I-OIS yinkqubo ehlawulela ukushukuma kwekhamera ngokuhambisa izinto zelensi kwicala elichasene nentshukumo. Isebenza ngokusebenzisa i-gyroscope kunye ne-accelerometer ukubona ukuhamba kwekhamera. Ulwazi oluvela kwezi luvo luthunyelwa kwi-microcontroller, ebala ubungakanani kunye nolwalathiso lwentshukumo ye-lens efunekayo ukuchasana nekhamera.

I-lens-esekelwe inkqubo ye-OIS isebenzisa iqela lezinto kwilensi ezinokuhamba ngokuzimeleyo kumzimba wekhamera.

Izinto ze-lens zifakwe kwiinjini ezincinci ezinokutshintsha indawo yazo ekuphenduleni intshukumo efunyenwe ngababonisi. Iimoto zilawulwa yi-microcontroller, ehlengahlengisa indawo yazo ukuchasana nokungcangcazela kwekhamera.

Kwikhamera, i-OIS isetyenziswa kwilensi ngokwayo, njengoko iyeyona ndlela isebenzayo yokubuyekeza ukushukuma kwekhamera. Nangona kunjalo, kwikhamera ye-CCTV, i-OIS inokuphunyezwa kumzimba wekhamera okanye kwi-lens, kuxhomekeke kuyilo kunye nokusetyenziswa.

Inkqubo esekwe kwilensi ye-OIS ineenzuzo ezininzi kunezinye iindidi zeenkqubo zokuzinzisa. Isebenza ngakumbi ekubuyekezeni ukushukuma kwekhamera, njengoko ingalungisa kuzo zombini iintshukumo ezijikelezayo kunye nezoguqulo. Ikwavumela ukukhawuleza kunye nezilungiso ezichanekileyo, njengoko izinto ze-lens zinokuhamba ngokukhawuleza nangokuchanekileyo ekuphenduleni ukunyakaza okufunyenwe ngababonisi.

Ukuqukumbela, i-OIS bubuchwepheshe obuphucule kakhulu umgangatho wemifanekiso ethathwe ziikhamera kunye neekhamera zeCCTV. I-lens-isiseko senkqubo ye-OIS yindlela esebenzayo nesebenzayo yokuhlawula ukushukuma kwekhamera, evumela imifanekiso ebukhali necacileyo nakwiimeko eziguquguqukayo. Ngokunyuka kwemfuno yomgangatho ophezulu wemifanekiso kwimiba eyahlukeneyo, i-OIS kulindeleke ukuba ibaluleke ngakumbi kwixesha elizayo.
