Yog hais tias koj tsis meej pem los ntawm "YOG" uas tej zaum yuav tacked rau lub xaus ntawm lub npe ntawm lub koob yees duab digital koj xav, koj tsis yog ib leeg. YOG, thaum siv nrog lub koob yees duab digital, yog luv luv rau "duab stabilization technology," uas tso cai rau lub koob yees duab los pab koj txo cov duab zais zis ntawm lub koob yees duab co.
Txawm hais tias lub koob yees duab duab stabilization tsis yog tshiab, ntau cov neeg siv digital cov koob yees duab tam sim no muaj xws li technology. Raws li YOG ntau tshaj qhov qub, nws tseem ceeb heev kom paub tias koj nyob nraum qhov twg, raws li cov duab stabilization muaj nyob rau hauv ob peb lub teeb meem sib txawv.
Qhov peb thawj cov teeb meem ntawm cov koob yees duab digital stabilization yog:
- Yooj yim kho
- Cov YOG
- Dual YOG
Cov Hauv Paus
Image stabilization technology siv cov cuab yeej los sis software hauv digital lub koob yees duab los txo cov teebmeem ntawm lub koob yees duab co los yog kev vibration. Lub koob yees duab blur yog qhia tau ntau dua thaum siv lub zoom zoom lens lossis thaum shooting nyob rau hauv cov neeg mob uas tsis tshua pom kev, qhov twg lub koob yees duab shutter ceev yuav tsum qeeb qeeb kom tso ntau lub teeb mus cuag lub koob yees duab duab sensor . Nrog ceev ceev ceev shutter, muaj kev co los yog co nrog tshwm sim nrog lub koob yees duab yog magnified, qee zaum ua rau cov duab zim zuag. Txawm tias koj lub cev los sis caj npab tsis taus zog yuav ua rau lub plab me ntsis.
YOG tsis tuaj yeem tiv thaiv txhua daim duab ploj zuj zus-xws li thaum twg ib lub ntsiab lus yog tsiv ceev ceev rau qhov kev siv ceev xwm-tab sis nws ua haujlwm zoo nrog txoj kev kho teeb meem tshwm sim los ntawm lub zog ntawm tus kws yees duab (tsis txhob xav phem; txhua tus kws yees duab muaj qhov teeb meem no puav). Cov kws tsim cov khoom kwv yees YOG tso cai rau koj tua ob peb qhov chaw ceev ceev qeeb dua koj ua tsis tau.
Yog hais tias koj tsis muaj lub koob yees duab uas muaj qhov zoo duab qhov ceev xwm, koj yuav tsum sim tua ntawm ceev ceev ceev, uas yuav tsis yooj yim rau cov neeg mob tsis tshua muaj teeb meem. Sim ua kom koj lub koob yees duab ISO qhov chaw kom koj tuaj yeem tua ntawm kev ceev ceev ceev ceev hauv lub teeb uas tsis tshua muaj siab yog tias lub koob yees duab qhov chaw ntawd tsis muab rau koj cov qhab-nees uas koj xav tau.
Yooj yim kho
Rau cov koob yees duab digital compact digital tsom rua cov pib thiab nruab nrab cov kev pabcuam, kev kho duab kho qhov muag (qee lub sijhawm luv rau OIS) yog qhov kev siv technology no.
Optical IS siv kho vajtse corrections rau tsis kam yees lub koob yees duab. Txhua lub chaw muag khoom muaj kev txawb rau kev siv qhov sib tw, tab sis feem ntau cov koob yees duab uas muaj kev kho qhov muag duab siv lub gyro sensor ua rau hauv lub koob yees duab uas ntsuas txhua lub zog los ntawm tus kws yees duab. Lub gyro sensor xa nws cov kev ntsuas los ntawm ib lub stabilization microchip mus rau lub CCD, uas hloov me ntsis los mus nplua. Lub CCD, lossis ntaus nqi txuas nrog, sau cov duab.
Kho kho vajtse kho nrog pom kho ntawm IS yog qhov tseeb tshaj plaws ntawm cov duab stabilization. Nws tsis tas yuav nce tus ISO sensitivity, uas tuaj yeem cuam tshuam duab zoo.
Cov YOG
Cov duab xim tsuas yog siv cov software thiab cov koob yees duab digital los txo cov teebmeem ntawm lub koob yees duab co. Yeej tseem zoo, cov YOG tsub kom ISO qhov kev txhawj xeeb, uas yog kev ntsuas ntawm lub koob yees duab ntawm lub siab. Nrog lub koob yees duab tau tsim ib qho duab los ntawm tsawg lub teeb, lub koob yees duab tuaj yeem tua ntawm ceev ceev ceev, uas minimizes blur ntawm lub koob yees duab co.
Txawm li cas los xij, YOG feem ntau ua rau lub siab tshaj ISO qhov tshaj qhov teeb meem tsis zoo ntawm lub koob yees duab hais tias nws yuav tsum yog rau cov teeb pom kev zoo ntawm kev txhaj tshuaj. Nce cov ISO rhiab heev nyob rau hauv zoo li no yuav degrade cov duab zoo, ua rau suab nrov ntau hauv cov duab-suab nrov yog txhua tus naj npawb ntawm cov pixels pseins uas tsis sau kom zoo. Nyob rau hauv lwm yam lus, thov lub koob yees duab los sim tsim ib qho duab ntawm tsawg dua-optimal ISO nqis yuav compromise duab zoo, thiab tus ntawd yog li cas yog tsis.
Qee cov koob yees duab kuj xa mus rau digital duab stabilization los piav txog ib daim software tsim rau hauv cov koob yees duab digital uas sim txo cov plooj tom qab koj yees duab, zoo ib yam li koj ua tau nrog cov duab software editing software hauv koj lub computer. Cov hom ntawm digital yog qhov zoo tshaj plaws ntawm txhua hom duab stabilization, tiam sis.
Dual YOG
Dual IS yog tsis heev li yooj yim rau tus pin, raws li manufacturers txhais nws txawv. Qhov feem ntau cov lus txhais ntawm cov duab dual stabilization muaj kev sib xyuam xim ntawm kev kho vajtse (raws li pom nrog kev kho IS) thiab muaj zog ISO ntau tshaj (li pom nrog cov YOG).
Qee lub sij hawm, siv cov duab yeeb yaj kiab los siv qhia txog qhov tseeb tias cov SLR (lens nkaus xwb) cov koob yees duab muaj duab yees duab yees hauv ob lub koob yees duab thiab hauv nws lub lens ntawm lub lens
Ua haujlwm tsis
Qee cov laus cov koob yees duab tsis muaj hom YOG. Txhawm kom tiv thaiv lub koob yees duab ntawm cov koob yees duab digital uas tsis muaj duab stabilization, sim ua cov tswv yim no:
- Mount koj lub koob yees duab ntawm ib lub kos.
- Siv lub koob yees duab qhov viewfinder, es tsis yog lub LCD, rau qhov ntsuas.
- Khaws koj tus kheej thaum koj tua los ntawm leaning tiv thaiv ib phab ntsa lossis qhov rooj.
- Tshem koj lub luj tshib ntawm koj lub cev hab tuav lub koob yees duab nrog ob txhais teg.
- Tua ntawm qhov ceev ceev ceev ceev txhua lub sijhawm, uas tsis yog ib qho kev xaiv.
Tsis txhob & Tsis txhob poobsiab
Thaum kawg, nco ntsoov koj to taub raws nraim li cas koj nyob nraum muas thaum nws los rau cov duab stabilization hauv koj cov koob yees duab. Qee cov chaw lag luam, tshwj xeeb tshaj yog cov uas muaj cov qauv qis, yuav siv cov ntsiab lus ntxig ntxaug, xws li kev thev naus laus zis los tiv thaiv kev siv tshuab, sim zais qhov tseeb tias lawv cov koob yees duab digital tsis muaj IS. Xws li cov koob yees duab feem ntau tsuas nce qhov kev ceev ceev kom txwv tsis pub muaj duab zais, uas qee zaum ua rau muaj teeb meem raug, yog qhov ua kom zoo dua qub.
Ua ib daim ntawv ntxiv, qee cov koos pij tawj muaj cov npe tshwj xeeb rau cov duab kho qhov muag, cov teeb meem ntxiv rau tus neeg lag luam (zoo li peb xav tau ntau yam tsis meej pem). Piv txwv, Nikon qee zaum siv "Kev Tiv Thaiv Kev Txwv," thiab Sony qee zaum siv "Super Steady Shot" rau kev kho qhov IS. Canon tau tsim ib hom duab stabilization uas nws feem ntau yog hais txog kev txawj ntse IS.
Ua ntej yuav ib qho qauv, nco ntsoov tias nws cov npe lag luam hais txog qhov kho qhov muag thiab tsis yog ib daim ntawv ntawm cov YOG. Koj yuav tsum muaj peev xwm nrhiav tau cov ntaub ntawv no rau ntawm tus kws muag khoom lub vev xaib lossis los ntawm tus neeg muag khoom muag ntawm koj lub koob thaij duab.
Feem ntau cov koob yees duab ntawm cov koob yees duab uas niaj hnub muaj xws li kho qhov muag los yog muaj xws li ib daim ntawv ntawm dual IS, yog li nrhiav tau lub koob yees duab zoo kom ua tau raws li koj cov kev xav hauv kev ruaj ntseg tsis yog qhov tseem ceeb ntawm kev txhawj xeeb raws li nws tau ob peb xyoos dhau los. Tseem, muaj ib qho zoo rau cov duab hauv kev lag luam yog qhov tseem ceeb heev rau koj cov koob yees duab kev vam meej uas nws tsim nyog saib xyuas koj lub koob yees duab tau zoo tshaj plaws ntawm YOG. Tsis txhob hnov qab xyuas lub koob yees duab daim ntawv teev cov lus qhia txog hom xwm duab uas muaj nyob rau hauv!
