Image stabilization thev naus laus zis txo cov duab tsis meej pem los ntawm lub koob yees duab co los ntawm ntau hom kev kho vajtse thiab kho software. Txawm hais tias lub koob yees duab kev ruaj ntseg tsis yog tshiab, ntau cov neeg siv khoom-theem cov koob yees duab tam sim no suav nrog IS thev naus laus zis.
Peb qhov kev teeb tsa tseem ceeb ntawm lub koob yees duab digital duab stabilization yog:
- Optical IS
- Digital IS
- Dual IS
Lub hauv paus ntawm Duab Stabilization
Image stabilization thev naus laus zis siv cov khoom siv kho vajtse lossis software hauv lub koob yees duab digital kom txo qis cov teebmeem ntawm lub koob yees duab co lossis kev co. Lub koob yees duab qhov muag plooj yog qhov qhia tau ntau dua nrog qhov ntev zoom lo ntsiab muag lossis thaum tua nyob rau hauv lub teeb qis, qhov twg lub koob yees duab lub shutter ceev yuav tsum tau qeeb dua kom tso cai rau lub teeb kom ncav cuag lub koob yees duab cov duab sensor. Nrog lub kaw lus qeeb qeeb, txhua qhov kev co lossis co tshwm sim nrog lub koob yees duab tau nthuav dav, qee zaum ua rau pom qhov muag tsis pom. Txawm tias me ntsis txav ntawm koj txhais tes lossis caj npab tuaj yeem ua rau qhov muag plooj me ntsis.
IS tsis tuaj yeem tiv thaiv txhua daim duab tsis pom tseeb-raws li thaum cov ntsiab lus txav nrawm dhau rau lub kaw lus nrawm uas koj siv-tab sis nws ua haujlwm zoo nrog kho qhov muag plooj tshwm sim los ntawm kev txav me ntsis ntawm tus kws yees duab. Cov neeg tsim khoom kwv yees IS kho pab koj tua ob peb lub kaw lus nrawm nrawm dua li qhov koj ua tau yam tsis muaj IS.
Yog tias koj tsis muaj lub koob yees duab uas muaj cov duab stabilization zoo, tua ntawm qhov nrawm nrawm dua. Sim ua kom koj lub koob yees duab qhov teeb tsa ISO kom koj tuaj yeem tua ntawm qhov nrawm nrawm hauv lub teeb qis yog tias lub koob yees duab teeb tsa tsis muab cov txiaj ntsig koj xav tau.
Optical IS
Rau cov koob yees duab digital compact tsom rau cov kws yees duab pib thiab nruab nrab, kho qhov muag duab stabilization yog qhov nyiam IS thev naus laus zis.
Optical IS siv kho vajtse kho kom tsis txhob cuam tshuam lub koob yees duab co. Txhua lub chaw tsim khoom qhia txog qhov sib txawv ntawm kev siv kho qhov muag IS, tab sis feem ntau cov koob yees duab digital uas muaj cov duab kho qhov muag siv lub gyro sensor ua rau hauv lub koob yees duab uas ntsuas txhua qhov txav los ntawm tus kws yees duab. Lub gyro sensor xa nws cov kev ntsuas los ntawm kev ruaj ntseg microchip mus rau CCD, uas hloov me ntsis kom them rov qab. Lub CCD, lossis cov khoom siv sib txuas, sau cov duab.
Kho kho vajtse pom nrog kho qhov muag IS yog daim ntawv meej tshaj plaws ntawm cov duab stabilization. Nws tsis tas yuav nce ISO rhiab heev, uas tuaj yeem cuam tshuam cov duab zoo.
Digital IS
Digital image stabilization tsuas yog siv software thiab digital lub koob yees duab teeb tsa kom txo qhov cuam tshuam ntawm lub koob yees duab co. Qhov tseem ceeb, digital IS tsub kom lub ISO rhiab heev, uas yog qhov ntsuas ntawm lub koob yees duab rhiab heev rau lub teeb. Nrog lub koob yees duab tsim cov duab los ntawm lub teeb tsawg, lub koob yees duab tuaj yeem tua ntawm qhov nrawm nrawm, uas txo qhov plooj ntawm lub koob yees duab co.
Txawm li cas los xij, digital IS feem ntau overrides ISO rhiab heev dhau qhov kev teeb tsa tsis siv neeg ntawm lub koob yees duab hais tias nws yuav tsum yog rau cov teeb pom kev zoo ntawm ib qho kev txhaj tshuaj. Kev ua kom cov ISO rhiab heev li ntawd tuaj yeem ua rau cov duab tsis zoo, ua rau muaj suab nrov ntau hauv cov duab-suab nrov yog ib tus lej ntawm cov pixels tsis zoo uas tsis sau zoo. Hauv lwm lo lus, thov kom lub koob yees duab sim tsim cov duab ntawm qhov chaw tsawg dua-zoo ISO tuaj yeem cuam tshuam cov duab zoo, thiab qhov ntawd yog qhov digital IS ua.
Qee lub koob yees duab kuj xa mus rau digital duab stabilization los piav txog ib daim software tsim rau hauv lub koob yees duab digital uas sim txo qhov plooj tom qab koj thaij duab, zoo ib yam li koj tuaj yeem ua nrog cov duab kho kom raug software ntawm koj. lub computer. Hom digital no yog qhov ua tau zoo tshaj plaws ntawm txhua hom duab stabilization, txawm li cas los xij.
Dual IS
Dual IS tsis yooj yim rau tus pin, raws li cov tuam txhab txhais nws txawv. Qhov feem ntau txhais ntawm dual duab stabilization muaj kev sib txuas ntawm kho vajtse stabilization (raws li pom nrog optical IS) thiab nce ISO rhiab heev (raws li pom nrog digital IS).
Qee zaum, dual duab stabilization yog siv los piav txog qhov tseeb tias lub koob yees duab ib leeg-lens reflex muaj cov duab stabilization thev naus laus zis hauv ob lub koob yees duab lub cev thiab hauv nws cov lo ntsiab muag sib hloov.
Ua haujlwm tsis yog
Qee lub koob yees duab digital qub tsis muaj hom IS. Txhawm rau tiv thaiv lub koob yees duab co hauv lub koob yees duab digital uas tsis muaj cov duab stabilization, sim cov lus qhia no:
- Ntau lub koob yees duab ntawm lub koob yees duab tripod.
- Siv lub koob yees duab qhov pom, tsis yog lub LCD, txhawm rau txhawm rau txhaj tshuaj.
- Txhob cia koj tus kheej thaum koj tua los ntawm kev ntswj ntawm phab ntsa lossis lub qhov rooj.
- Cia koj lub luj tshib rau ntawm koj lub cev thiab tuav lub koob yees duab nrog ob txhais tes.
- Tua ntawm qhov nrawm nrawm txhua lub sijhawm, uas tsis yog ib qho kev xaiv ua tau zoo.
Tsis txhob dag
Qee lub tuam txhab, tshwj xeeb tshaj yog cov qauv uas tsis tshua muaj nqi, siv cov lus tsis raug, xws li kev tiv thaiv plooj lossis tiv thaiv kev co, sim zais qhov tseeb tias lawv lub koob yees duab digital tsis muaj IS. Cov koob yees duab zoo li no feem ntau tsuas yog nce qhov nrawm kom txwv cov duab tsis pom tseeb, uas qee zaum ua rau lwm yam teeb meem raug, yog li ua rau cov duab tsis zoo.
Qee lub koob yees duab digital cov tuam txhab siv cov npe tshwj xeeb rau kho qhov muag duab stabilization, ntxiv cov khoom nyuaj rau cov neeg siv khoom. Piv txwv li, Nikon qee zaum siv Vibration Reduction, thiab Sony qee zaum siv Super Steady Shot kom xa mus rau qhov kho qhov muag IS. Canon tsim ib hom duab stabilization uas nws feem ntau hu ua Intelligent IS.
Cov koob yees duab digital niaj hnub no tsuas yog suav nrog kho qhov muag IS lossis suav nrog qee hom IS dual, yog li nrhiav lub koob yees duab zoo kom tau raws li koj qhov xav tau kev ruaj ntseg duab tsis yog qhov tseem ceeb ntawm kev txhawj xeeb li nws yuav tau ntau xyoo dhau los. Tseem, muaj cov duab stabilization zoo yog qhov tseem ceeb heev rau koj lub koob yees duab digital txoj kev vam meej uas nws tsim nyog muab ob npaug rau kev kuaj xyuas koj lub koob yees duab muaj hom zoo tshaj plaws ntawm IS. Tsis txhob hnov qab xyuas lub koob yees duab cov npe tshwj xeeb rau hom duab stabilization uas muaj.
