Cov khoom pov thawj zoo tshaj plaws yog qhov tseem ceeb tshaj rau cov tuam txhab lag luam luam kom muaj kev sib tw zoo dua. Nyob rau hauv cov luam ntawv ntau lawm, yuav ua li cas kom tau cov luam tawm nrog kev sib raug zoo nrog cov qauv pov thawj tau ib txwm ua cov tsom xam cov luam ntawv. Yog li, kev xaiv ntawm tus qauv pov thawj rau kev txiav txim siab tias cov ntawv luam tawm tau tsim nyog lossis tsis, qhov zoo thiab zoo cov qauv, thiab kev tswj tom ntej ntawm cov txheej txheem luam ntawv yog qhov tseem ceeb.
1. Cov qauv kev tshawb nrhiav pov thawj tam sim no thiab cov teeb meem uas twb muaj lawm
Hauv kev lag luam luam txwm ua, nws muaj peb txoj hau kev xaiv cov qauv pov thawj: ib qho yog raws qhov tseem ceeb ntawm cov cai; lwm tus yog daim ntawv pov thawj raws li cov pov thawj uas tau ua los ntawm cov qauv tseeb; qhov thib peb yog lub tshuab luam ntawv hauv cov txheej txheem luam ntawv. Cov kev paub thiab cov cwj pwm yog siv los mus tshem cov pov thawj, thiab cov kev kuaj zoo ntawm cov khoom muab rho tawm raug tshawb xyuas (feem ntau yog los ntawm kev kuaj cov xim ntawm cov kev tswj kav, ntxiv los ntawm tib neeg lub qhov muag kom pom cov duab tag nrho), thiab cov qauv uas tau ntsib tus neeg tus qauv cov qauv no raug xaiv ua cov qauv pov thawj. Txawm li cas los xij, peb txoj hau kev no muaj qee qhov chaw tsis txaus siab.
Thaum tus thawj yog daim duab los yog duab, qhov defect ntawm qhov luam tawm nws tus kheej (kev sib cais, kev ntsuam xyuas, kev luam xim gamut, thiab lwm yam) ua rau nws nyuaj rau qhov kawg luam cov khoom mus txog theem ntawm thawj, thiab nws yog tsis tsim nyog mus ntsuas thiab kho cov ntawv luam tawm raws li daim tseem cia nrog. .
Thaum twg daim ntawv pov thawj yog siv los ua cov ntawv pov thawj, txij li ntawv, zauv, thiab lwm yam siv rau cov ntaub ntawv pov thawj sib txawv ntawm qhov kev luam ntawv, thiab muaj qhov sib txawv ntawm cov pov thawj gamut thiab cov luam ntawv gamut, ces cov xim ntawm cov pov thawj Daim ntawv no yog nruab nrab ntawm cov ntawv sau thiab cov nqi luam. Cov xim txawv tsis yoojyim, thiab cov deviations no feem ntau tsis yooj yim rau kev tshem tawm. Yog li ntawd, xa mus rau cov ntawv pov thawj los txiav txim qhov tseeb ntawm cov khoom luam tawm, thiab kev hloov thiab kev tswj ntawm cov ntawv tom ntej yuav raug siv, ua rau pov tseg cov ntawv luam tawm thiab sij hawm ua haujlwm, uas tsis yog qhov zoo rau kev ua haujlwm tas li qub ntau lawm.
Txawm hais tias txoj kev xaiv cov qauv pov thawj los ntawm cov ntawv txheeb cais los ntawm cov teeb meem ntawm cov xim txawv gamut ntawm cov txheej txheem qauv thiab cov nqi luam tawm, tej zaum tseem yuav muaj lwm yam kev tsis txaus siab vim qhov nws muaj zog randomness thaum xaiv cov nplooj ntawv sau: Muab cov ntaub ntawv pov thawj Nws yuav tsis yog qhov tseeb ntawm cov ntaub ntawv luam tawm. Yog hais tias nws tshwm sim nyob rau hauv cov txheej txheem luam ntawv (xws li cov xoos luam ntawv xoos, tsis muaj teeb meem loj ntawm lub ploj ntawm qhov qis, cov teeb meem ntawv, thiab lwm yam), thaum cov luam ntawv hloov lawm, nws yuav ua rau kev txiav txim siab loj. Vim tias tus qauv coj tawm hauv lub sij hawm no kuj yog qhov zoo tshaj plaws, los yog nws yuav yog qhov phem tshaj plaws, tsuas yog cia li hloov, tsis yog qhov sawv cev ntawm lub xeev ntawm lub tshuab.
2. Lub hauv paus ntsiab lus thiab kev coj ua raws qauv ntawm cov qauv qauv tawm raws li cov ntaub ntawv tawm
Nws tuaj yeem pom los ntawm cov saum toj no kev soj ntsuam hais tias txoj kev rho tawm ntawm cov qauv siv pov thawj feem ntau tsis tsim nyog. Yog li no, daim ntawv no tau muab cov qauv ntawm kev tshawb nrhob raws li cov qauv pov thawj ntawm cov ntawv sau cov kev sib tw ntawm cov ntawv sau.
Ua ntej, cov nplooj ntawv luam tawm raws li cov xwm txheej ruaj khov hauv kev ruaj ntseg tau raug xaiv ua cov pov thawj kev sim. Xav tias muaj tag nrho cov ntawv txheeb (naj npawb No. 1, Tsis muaj. 2, Zauv 3, ... n), cov ntsiab lus ntawm kev xeem tau teem nyob rau tib qho chaw ntawm txhua daim ntawv, thiab qhov tseem ceeb ntawm qhov kev ntsuam xyuas raug ntsuas nyob rau hauv tib lub sijhawm soj ntsuam. Raws li cov ntaub ntawv chromaticity ntawm cov ntsiab lus ntawm kev xeem, cov qauv pov thawj raug xaiv los ntawm kev xam thiab kev tsom xam. Cov kauj ruam tshwj xeeb yog raws li nram no:
2.1 Ua ntej, siv daim ntawv "No. 1" uas yog "standard" pov thawj, xam cov xim sib txawv ntawm cov ntawv xeem ntawm cov ntawv tshuav thiab cov ntsiab lus xeem ntawm qhov "standard" pov thawj, thiab nyhav cov lej ntawm cov xim sib txawv ntawm txhua tus taw tes;
2.2 Tom qab ntawd siv thib 2, 3, 4th ... n luam tawm ua qhov "standard" proofs, thiab xam cov xim txawv qhov hnyav ntawm thawj kauj ruam;
2.3 Raws li qhov hnyav tag nrho ntawm cov chromatic aberrations, pom tias daim ntawv nrog lub me tshaj chromatic aberration ceeb thawj ntawm txhua daim ntawv yog qhov txheem pov thawj.
Qhov zoo ntawm qhov no yog hais tias, raws li lub hom phiaj cov ntsiab lus ntawm qhov tseeb cov ntaub ntawv, los ntawm kev xam thiab kev sib piv, tus cwj pwm ntawm tib neeg yam ntxwv ntawm kev coj tus qauv rho tawm yog raug zam, thiab qhov kev xaiv raug tsim nyog tshaj qhov feem ntau siv txoj kev rho tawm ntawm kev siv; Kev pov thawj ntawm qhov tsis ncaj ncees ntawm tus txheej txheem luam ntawv, txo cov kev ua yuam kev loj; kov cov kev siv pov thawj raws li kev siv, vim tias cov ntawv pov thawj ntawm cov ntawv, tus lej, thiab lwm yam txawv ntawm qhov kev luam ntawv, thiab tsis muaj tseeb tiag txog lub tshuab luam tawm Hauv qhov teeb meem, nws tsis muaj peev xwm muab qhov tseeb rau tom qab luam ntawv kev hloov kho.
3. Kev sim
200 nruam prints nyob rau hauv cov txheej txheem luam ntawv tau raug xaiv raws li kev sim pov thawj. Cov ntawv txheeb raug muab faib rau cov chaw luam tawm, thiab cov ntsiab lus ntawm cov lej muaj nyob rau ntawm qhov ntev ntawm cov lej ntawm cov lej thiab cov lej cim. Qhov chaw ntawm txhua qhov kev xeem yog pom hauv daim duab 1.
Daim Duab 1 Daim duab ntawm qhov kev ntsuas rau ntawm daim ntawv luam tawm
Cov ntaub ntawv chromaticity ntawm txhua qhov kev xeem taw tes rau ntawm cov ntawv txheeb zoo tau ntsuas. Ntawm kev xam, cov xim txawv qhov hnyav ntawm qhov seem uas tau txais thaum txhua daim ntawv yog siv ua pov thawj. Raws li pom hauv daim duab 2:
Daim duab 2: Kev sib cais ntawm cov xim qhov txawv ntawm cov ntawv seem hauv qab thaum txhua daim ntawv yog siv ua pov thawj
Nws tuaj yeem pom los ntawm cov ntaub ntawv muab xam tias thaum tsis muaj daim ntawv luam tawm 96 uas yog siv tus qauv pov thawj, qhov nyhav sib txawv ntawm txhua daim ntawv yog qhov tsawg tshaj plaws. Yog li, qhov pov thawj ntawm qhov kev xeem no yog daim ntawv 96th luam.
Tam sim no siv cov ntawv txheeb xaiv los ua cov qauv pov thawj, ua cov ntsiab lus ntawm cov ntawv sib txawv ntawm cov ntawv sib txawv, piv qhov nruab nrab qhov tseem ceeb ntawm cov xim sib txawv ntawm cov xim tib yam, thiab cov nqi tseem ceeb raws li qhia hauv Table 1:
Table 1 Xim qhov txawv txhais tau tias cov lus qhia ntawm kev xeem xim thaiv thaum qee cov ntawv txheeb xyuas tau
Cov ntaub ntawv muaj nqis nyob rau hauv Table 1 yog cov qauv pov thawj ntawm daim ntawv 96th luam. Ntawm qhov 7 cov ntsiab lus xaiv tau xaiv, tsuas yog qhov nruab nrab ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov ntawv xeem 15th thiab 35th yog me ntsis loj tshaj qhov nruab nrab ntawm cov xim txawv thaum cov nplooj ntawv raug siv ua tus qauv pov thawj. Qhov no qhia tau hais tias cov qauv ntawm daim ntawv no yog qhov tsim nyog tshaj qhov qub coj mus kuaj qauv coj.
4 Xaus
Tsab ntawv no tawm tswv yim tshiab rau txoj kev xaiv cov qauv pov thawj los ntawm cov tshooj luam tawm. Piv nrog rau cov ntaub ntawv pov thawj hauv cov ntawv pov thawj hauv kev sib tw, nws muaj kev tiv thaiv ntawm cov tib neeg yam hauv cov qauv qes thaum siv cov qauv qis mus rau ib qho twg, uas yog ntau raws li cov sij hawm luam ntawv, thiab muab tau lub hauv paus rau kev ntsuam xyuas ntawm kev luam zoo thiab kev tswj thiab kev hloov ntawm cov ntawv tom ntej.
