Tam sim no sab nraum zoov coj zaub screen yog dav siv, kev tshaj tawm sab nraum zoov, kev qhia tsheb, kev tshaj tawm tshaj tawm, thiab lwm yam, yuav koom nrog sab nraum zoov coj zaub loj, LED zaub npo tuaj yeem pom txhua qhov chaw, coj mus muag LED zaub screen los ntawm lub tuam txhab lossis kev lag luam nyiam, yog ntau yam ntawm cov ntaub ntawv tshaj tawm, tshaj tawm thiab tshaj tawm kev xaiv, tso saib me me pixel yog maj mam dhau los ua qhov kev xaiv tseem ceeb rau cov ntaub ntawv niaj hnub. Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib ntawm kev siv thev naus laus zis, qhov pom tseeb ntawm cov duab pixel me me ntawm cov zaub yuav ua tau zoo dua. Txij li cov duab tau pom meej dua thiab meej dua, ces qee zaum peb yuav pom qee cov dej ripples nyob rau sab saum toj ntawm LED zaub, kab txaij, yog dab tsi? Cov zaub tsis zoo? Qhov tseeb, qhov no yuav yog qhov tshwm sim moire ntawm cov zaub.
Dab tsi yog qhov cuam tshuam moire ntawm LED zaub?
Nyob rau hauv kev lag luam terminology ntawm pitch coj zaub, muaj ib tug phenomenon hu ua moire los yog dej ripple zaub, uas ua rau cov tsos ntawm ib tug kab txaij, flickering ntawm sab saum toj thiab hauv qab, ua rau tsis zoo saib tshwm sim thaum tua LED zaub nrog xov tooj ntawm tes los yog cov kws tshaj lij. cov khoom siv video. Yog li tsim qhov phenomenon hu ua moire. Qhov tseeb, cov nyhuv moire yog ib qho teeb meem tshwm sim heev, tshwm sim los ntawm LED zaub moire yog qhov laj thawj tseem ceeb ntawm qhov laj thawj tseem ceeb yog LED zaub refresh tus nqi qis dhau. LED zaub pitch me me refresh npaum li cas tuaj yeem nce mus rau 3840Hz, koj tuaj yeem txo qhov tshwm sim ntawm moire, yog tias peb cov zaub LED yog tus nqi qis ntawm qhov tshiab, ces tib neeg lub qhov muag saib nws tsis yog teeb meem, tab sis yog tias koj siv lub xov tooj ntawm tes los yog yees duab lub koob yees duab tua, nws yuav yog ib lub tswv yim zoo uas yuav siv lub xov tooj ntawm tes los yog yees duab yees los tua. Los yog video koob yees duab shooting, yuav muaj moire nyhuv, qhov tshwj xeeb kev ua tau zoo yog LED zaub yuav tshwm nyob rau hauv ib tug dub kab rov tav kab, yog hais tias lub dynamic saib yuav yog ib tug flash. Yog hais tias lub pixel pitch coj me me, qhov me me pixel pitch duab tso saib cov nyhuv yuav zoo dua, lub koob yees duab los ntawm LED cov duab nyob deb tuaj yeem nyob ze dua, qhov qis dua qhov tshwm sim ntawm moire, qhov zoo thiab yoog raws ntawm cov yeeb yaj kiab yuav zoo dua.
Cov txheej txheem ntawm kev tsim moire ntawm LED zaub screen
LED zaub pixel faib ceev yog raws nraim ntawm CCD tuaj yeem paub qhov txawv ntawm lub sijhawm, inevitably, lub koob yees duab digital tseem yuav tau txhais ib feem ntawm cov txiaj ntsig tuaj yeem lees paub, tab sis kuj tseem yuav ntxiv rau cov nplai grey tsis tuaj yeem lees paub, thiab ob thiab tsim ntawm cov qauv tsis tu ncua, cov tshuaj tiv thaiv hauv qhov muag pom yog lub sijhawm ripples.
Moire nyhuv yog qhov pom kev pom, thaum saib ib pawg kab lossis cov ntsiab lus superimposed ntawm lwm pawg kab lossis cov ntsiab lus tshwm sim, uas txhua pawg kab lossis cov ntsiab lus ntawm cov txheeb ze lossis qhov sib txawv. Tom qab ntawd cov nyhuv moire tau piav qhia saum toj no tshwm sim. Yuav kom paub meej dua, nws yog ob qhov sib txawv me ntsis kab txaij sib txawv, lawv sab laug kawg ntawm txoj kab dub txoj hauj lwm yog tib yam, vim qhov sib txawv ntawm qhov sib txawv, mus rau sab xis maj mam kab kab txaij tsis tuaj yeem sib tshooj. Ob kab txaij sib tshooj, sab laug ntawm kab dub vim sib tshooj, yog li koj tuaj yeem pom kab dawb. Thiab sab xis maj mam misaligned, kab dawb tawm tsam cov kab dub, sib tshooj ua rau tag nrho cov dub. Muaj cov kab dawb thiab tag nrho cov kev hloov dub uas ua rau cov kab txaij moire.
Yuav ua li cas tshem tawm moire nyhuv ntawm LED screen?
Kev kho lub koob yees duab
1, hloov lub koob yees duab lub kaum sab xis: vim lub koob yees duab ntes lub kaum sab xis ntawm cov khoom yuav ua rau Moire ripples, hloov lub kaum sab xis ntawm lub koob yees duab, los ntawm kev tig lub koob yees duab, koj tuaj yeem tshem tawm lossis hloov lub xub ntiag ntawm Moire ripples.
2, hloov lub koob yees duab tsom: pom tseeb dhau lawm thiab cov ntsiab lus siab yuav ua rau Moire Ripple, hloov qhov tsom tuaj yeem hloov qhov pom tseeb, uas nyob rau hauv lem yuav pab tshem tawm Moire Ripple.
3, kho lub koob yees duab kev teeb tsa tsis: xws li lub sij hawm raug, aperture thiab ISO, thiab lwm yam, kom tsis muaj zog ntawm cov nyhuv moire, sim ntau yam kev teeb tsa los kho kom pom qhov sib xyaw ua ke ntawm qhov tsim nyog tshaj plaws.
4, kev siv daim iav pem hauv ntej lim ntsia ncaj qha rau pem hauv ntej ntawm CCD, kom nws cov xwm txheej raug kom tau raws li qhov ntau zaus, lim cov duab ntawm qhov siab spatial zaus, txo cov LED zaub moire tshwm sim, tab sis qhov no kuj tseem yuav synchronize rau. txo qhov sharpness ntawm daim duab.
Technical txhais tau tias
Kev siv software rau kev ua cov duab tom qab ua tiav. Duab editor Photoshop, thiab lwm yam., kom tshem tawm cov tsos ntawm moire ntawm daim duab kawg, nrog rau cov duab plooj, txo suab nrov, thiab cov duab sib piv, thiab lwm yam, kom cov duab zoo dua thiab cov duab zoo dua.
Lub cev
Siv cov tshuaj tiv thaiv Moore, muaj cov txheej txheem tshwj xeeb thiab cov khoom siv uas tuaj yeem txo cov nyhuv Moore. Cov txheej txheem no tuaj yeem siv rau ntawm LED vaj huam sib luag lossis teeb pom kev zoo kom txo tau qhov cuam tshuam cuam tshuam. Cov txheej txheej no feem ntau yog tsim los hloov cov refraction lossis tawg cov khoom ntawm lub teeb, yog li txo kev cuam tshuam.
Qhov tseeb, tom qab paub txog qhov ua rau pom moire, peb tuaj yeem paub yuav ua li cas tshem tawm nws. Qhov tseeb, txoj hauv kev zoo tshaj plaws los daws qhov teeb meem ntawm LED zaub moire yog siv lub siab txhuam LED zaub, kom qhov tshwm sim moire yuav tsis tshwm sim. Vim yog kev siv 3840H2 high-brush LED zaub, ces txawm tias lub xov tooj ntawm tes los tua, cov yeeb yaj kiab yuav tsis muaj qhov hloov pauv, vim tias tus naj npawb ntawm lub sijhawm LED zaub yog refreshed ib chav tsev ntawm lub sij hawm ntau tshaj li tus txhuam qis dua. ob npaug, yog li cov khoom siv ua yeeb yaj kiab tsis tuaj yeem pom.
Yog tias tus neeg siv tau yuav thiab siv lub teeb txhuam LED qis, koj tuaj yeem mus los ntawm txoj kev saum toj no los kho, txo lossis tshem tawm moire. Kev tshaj tawm kev tshaj tawm qis-txhuam coj mus muag LED zaub yog txaus, yog tias koj xav siv nyob rau hauv ib qho kev tshaj lij scene, yuav siv ntau cov duab los txhawb cov lus tshaj tawm, koj tuaj yeem mus raws li cov peev nyiaj yuav, txawm tias nws yuav nce ib co tus nqi, tab sis tus yees duab shooting yuav yooj yim dua thiab ceev, lub zuag qhia tag nrho cov nyhuv yog zoo dua, zoo dua saib kev.
