Hauv kev lag luam ntawm phau ntawv thiab ntim tshuab luam ntawv, xim luam ntawv tau dhau los ua qhov tseem ceeb ntawm kev luam ntawv, thiab qhov zoo ntawm cov ntawv luam tawm yog kev txhim kho niaj hnub. Txawm li cas los xij, vim yog cov ntsiab lus thiab lub hom phiaj, tsis muaj ntau yam khoom zoo, uas tseem tsis tuaj yeem muab piv nrog cov khoom lag luam zoo txawv teb chaws. Peb paub tias qhov zoo ntawm cov xim luam tawm yog nyob rau ntau yam hauv cov txheej txheem luam tawm, xws li cov suab nrov ntawm cov xim qub duab, dot expansion tus nqi, xim tshuav nyiaj li cas thiab lwm yam kev txwv, thiab ntawm lawv, qhov zoo ntawm pre- xovxwm duab ntau lawm ncaj qha txiav txim siab zoo ntawm cov xim luam ntawv cov khoom, txawm hais tias nyob rau hauv phaj luam ntawv yuav tsum tau kho ib feem rau ib co deficiency, tab sis luam tawm ib tug zoo cov khoom yog yeej tsis muaj hwj chim. Yog li ntawd, thaum ua cov duab prepress, yog tias qhov zoo ntawm cov ntawv sau qub tau pom tias tsis txaus, nws yuav tsum raug kho. Hauv qab no, cov lus qhia luv luv rau qee cov txheej txheem ua thiab cov txheej txheem.

 

I. Yuav tsum muaj cov ntawv sau qub

(1) Qhov ntom ntawm cov ntawv sau qub

Qhov sib txawv ntawm qhov siab tshaj plaws thiab qhov tsawg kawg nkaus ceev ntawm cov ntawv sau qub (uas yog, qhov sib piv), tam sim no tus nqi siab tshaj plaws ntawm cov ntawv luam tawm tuaj yeem ncav cuag 1.8, qhov siab tshaj plaws ntawm cov ntawv luam ntawv tuaj yeem ncav cuag 1.7, thiab qhov ntom ntawm tus cwj mem dub ntawm cov ntawv sau qub yog 1.8. Feem ntau hais lus, txhua qhov ceev ntawm cov ntawv sau qub tsuas tuaj yeem tsim tawm hauv thaj tsam ntawm 0 ~ 1.8 ntawm daim ntawv dawb.

 

Yog li ntawd, rau cov ntawv sau qub, muaj qhov ntom ntom haum rau cov ntawv luam ntawv phaj. Thaum qhov ntom ntom ntawm cov ntawv sau qub loj dhau lawm, qhov rhiab heev ntawm lub tshuab luam ntawv thiab cov hluav taws xob txuas ntxiv mus rau qhov dhau ntawm qhov ntom ntom qis, yog li qib ntawm cov xim sib cais phaj yog qhov tiaj tus. Raws li kev xyaum, cov ntawv sau qub yog 0.3 ~ 2.1, uas yog, qhov sib piv yog 1.8 thaum qhov tsim nyog tshaj plaws. Xim tsis zoo zaj duab xis thawj qhov sib txawv yog tswj tsis pub dhau 2.4; Yog tias qhov sib piv ntawm cov ntawv sau qub yog tsawg dua 2.5, cov nyhuv ntawm qhov tsim nyog compression thaum luam tawm kuj zoo tagnrho. Yog tias qhov sib piv ntawm cov ntawv sau qub yog ntau dua 2.5, txawm tias cov kauj ruam compression tau ua thaum luam tawm, cov khaubncaws sab nraud povtseg yuav poob ntau dhau thiab cov nyhuv tsis zoo.

 

(2) Xim tsis zoo ntawm cov ntawv sau qub

Feem ntau, muaj tag nrho cov xim tsis zoo, tsis tshua muaj xim tsis zoo, siab profile xim bias thiab siab profile xim tsis zoo ntawm cov xim sib txawv (uas yog, xim sib txawv). Yog li ntawd, thaum kho los xav txog tag nrho, tsis tuaj yeem pom ib nrab xim tam sim ua cov xim, txwv tsis pub nws yuav ua rau lwm cov xim ib nrab.

 

(3) Qib ntawm cov ntawv sau qub

Muaj peb lub ntsiab indexes los ntsuas qhov zoo ntawm replica, uas yog, theem, xim thiab clarity, thiab theem yog qhov tseem ceeb tshaj plaws. Cov qib ntawm cov ntawv sau ib txwm yuav tsum muaj daim duab tsis dhau ci thiab tsaus, siab, nruab nrab thiab qis profile, ceev hloov series, nplua nuj suab thiab lwm yam ntxwv.

 

2. Cov ntawv sau cov teeb meem xim thiab txoj kev kho mob

Qhov tseeb lub suab ntawm cov ntawv sau ncaj qha tuaj yeem pom ncaj qha los ntawm kev ntsuas ntawm peb-xim qhov sib txawv thiab cov lus piav qhia ntawm peb-xim density nkhaus. Kev luam tawm xim luam tawm faib qhov ntom ntom ntawm cov ntawv sau qub thiab luam tawm ua plaub ntu, uas yog, qhov ntom ntom ntawm qhov taw tes taw tes thiab qhov tsaus nti yog muab faib ua lub suab nrov, suab nruab nrab thiab lub suab tsaus, thiab thaj tsam tsawg dua qhov qhov ntom ntom ntawm qhov taw tes tseem ceeb yog hu ua qhov tseem ceeb heev.

 

Hauv kev tsom xam ntawm cov xim zoo ntawm cov ntawv sau qub, yog tias peb xim qhov sib txawv thiab qhov sib txawv yog qhov zoo ib yam, nws txhais tau hais tias nws tsis yog xim xim, lub suab yog qhov qub; Yog tias qib ua tiav, qib yog nplua nuj, thiab kev faib tawm yog tsim nyog, txawm tias tag nrho qhov sib txawv me ntsis txawv, nws tuaj yeem suav tias yog cov ntawv sau ib txwm muaj. Cov xim luam tuaj yeem raug kho raws li cov ntaub ntawv tsis raug xim ib txwm, thiab qhov tseem ceeb yog muab tso rau ntawm qib luam.

 

Yog hais tias qhov ntom ntawm peb xim txawv, nws qhia tau hais tias nws yog biased rau ib yam xim, tab sis qhov sib piv ntawm qhov ntom ntawm peb xim yog qhov sib npaug, uas yog qhov sib npaug ntawm cov xim. Cov xim ib nrab ntawm cov qauv no yog qhov zoo tshaj plaws raws li peb-xim xim nkhaus, tsim los kho peb-xim grey tshuav nyiaj li cas ntawm hierarchical replication nkhaus, kom cov xim ntawm tag nrho cov suab yog kev sib koom ua ke.

 

Yog tias qhov sib txawv ntawm qhov sib txawv ntawm qhov ci peb xim yog qhov loj, qhov ceev ntawm qhov tsaus ntuj peb xim yog nyob ze rau tib yam, cov xim tsis ncaj ncees feem ntau tshwm sim nyob rau hauv qhov chaw siab profile, uas yog qhov tsis zoo rau kev luam tawm ntawm qib siab profile ntawm cov khoom siv. duab. Nws yog qhov zoo tshaj plaws los txiav txim siab peb-xim nkhaus los tsim cov qauv hierarchical daim ntawv nkhaus ntawm peb-xim phaj, hloov qhov chaw ntawm peb-xim dot ntawm qhov tseem ceeb ntawm daim duab sib cais xim, thiab kho qhov siab profile xim bias kom raug. .

 

Yog hais tias peb-xim qhov ntom ntawm qhov tseem ceeb hauv cov ntawv sau tseem ceeb yog qhov zoo ib yam, tsuas yog peb-xim qhov ntom ntawm cov suab nrov kawg sib txawv, thiab qhov sib txawv ntawm qhov sib txawv kuj txawv, cov xim tsis zoo yog pom tseeb hauv nruab nrab mus rau qhov tsaus ntuj. suab nrov, lub suab tsaus me ntsis poob, thiab lub suab nrov yog qhov qub.

 

Muaj peev xwm hloov cov xim tsaus nti peb-xim dot cov ntaub ntawv teeb tsa ntawm cov duab sib cais xim, lossis ntxiv cov xim ntawm cov xim tag nrho cov xim tom qab tshem tawm (tsuas yog rau cov xim sib xyaw). Txawm li cas los xij, thaum cuam tshuam nrog cov xim tsis zoo ntawm cov ntawv sau qub, nws yuav tsum tau them sai sai rau qee qhov kev ua yeeb yam tsim los ntawm tus sau, xws li cov duab backlight.

 

Hauv kev luam ntawv, feem ntau muaj peb lub ntsiab lus sib txawv ntawm cov xim luam tawm. Ib qho yog lub cev kev xav ntawm cov xim luam tawm, yuav tsum muaj cov xim qub hauv txhua qhov xim spectral faib yog tib yam. Qhov thib ob yog qhov chrominance ntawm kev nkag siab ntawm kev yug me nyuam, yog li ntawd cov duab luam tawm luam tawm thiab cov ntsiab lus ntawm cov xim qub hauv cov xim ntawm tib los yog ze, uas yog, sib txawv spectrum nrog tib xim nyhuv, uas yog lub hom phiaj ntawm kev ntsuam xyuas qhov tseeb. ntsuas tus qauv ntawm cov xim luam tawm. Qhov thib peb yog kev puas siab puas ntsws ntawm cov xim luam tawm, uas yog, luam ntawv luam tawm ntawm cov xim, hauv chroma nrog cov xim qub yuav muaj qee qhov sib txawv, tab sis hauv cov xim xim tuaj yeem ua tiav qhov pom kev puas siab puas ntsws.

 

Lub hauv paus ntsiab lus ntawm kev tsim cov xim yog los kho cov grey hauv cov ntawv sau qub. Txhawm rau ntsuas qhov luam tawm ntawm grey tshuav nyiaj li cas, cov xim densitometer tuaj yeem siv los ntsuas qhov peb-xim nruab nrab grey nplai txuas nrog rau cov ntawv luam tawm, lossis ntsuas peb-xim optical ntom ntawm daim duab uas yuav tsum yog qhov nruab nrab grey theem. Yog tias kev soj ntsuam siv tsis yog kev txiav txim siab, nws yog ib qho tsim nyog los sib piv cov qib grey hauv cov duab luam tawm nrog tus qauv nruab nrab grey thaiv nyob rau hauv cov xwm txheej uas lub teeb ci thiab cov xim ambient kub yog tus qauv heev.

 

3. Cov ntaub ntawv qib siab ceev teeb meem thiab txoj kev kho mob

Rau cov ntawv sau nrog ntau qib ntawm qhov ntom thiab zoo, cov txheej txheem ua haujlwm sib txawv ntawm cov ntawv sau rau cov ntawv sau.

 

(1) Ib txwm raug, qhov sib txawv ntom ntom

Nws lub ntsiab yog nyob rau hauv lub suab nrov, nruab nrab lub suab, thiab lub brightness yog proportional rau lub brightness ntawm tus txheej txheem tshiab ntawm 4 ~ 6.

 

(2) Cov ntawv sau zoo sib xws

Qhov ceev tsawg yog {{0}}.3 ~ 0.5, thiab qhov siab ceev yog 2.4 ~ 2.8, uas yog ze rau tus qauv thawj cov ntawv sau. Ntxiv nrog rau qhov sib txawv ntawm cov kauj ruam sib txawv ntawm cov ntawv sau qub, kev hloov kho hierarchical yog ua raws li cov kauj ruam hierarchical reproduction nkhaus ze rau tus qauv, uas tuaj yeem ua tiav cov txiaj ntsig zoo. [tom ntej]

 

(3) High contrast phau ntawv

Lub ntsiab lus ceev tsis yog siab dua {{{{{{3, thiab ntxoov ntxoo zoo sib piv yog loj heev, qib dav ntawm cov nruab nrab theem yog nplua nuj thiab ua tiav, lub brightest thiab darkest theem cheeb tsam piv tsis loj. Hauv cov ntawv sau zoo li no, thaum ua qhov tseem ceeb thiab xaiv qhov tsaus ntuj, theem nrab ntawm ob qhov kawg tuaj yeem raug tshem tawm kom txo qhov ntsuas ntawm nws daim ntawv.

 

(4) Cov ntawv sau tsis sib xws

Lub suab sib piv yog qis dua 1.7, thiab qhov tseem ceeb ceev yog hauv qab 0.3. Lub ntsiab ntawm cov ntawv sau yog lub teeb thiab nyias, thiab qhov ci ntsa iab yog siab. Nws yog nyob rau theem 7 thiab 8 ntawm tus txheej txheem tshiab ntawm qhov ci. Kev tsim tawm kom tob rau daim ntawv luam, kom txo qhov ci ci, ze rau tus qauv ci ntsa iab. Nyob rau hauv cov ntaub ntawv no, nws yog tsim nyog los ntxiv dag zog rau lub hierarchical luam thiab redistribution ntawm kaj thiab nruab nrab tone, thiab qhov ceev ntawm dub thiab dawb teb calibration yuav tsum me me. Lub hierarchical nkhaus ntawm lub suab nrov thiab nruab nrab yuav tsum sib sib zog nqus me ntsis kom ua tau zoo dua qub hierarchical sib piv thiab pom qhov ci ci. Raws li cov duab ntawm nws cov hierarchical faib nkhaus, nws lub suab nrov yuav tsum txawv nyob rau hauv lub teeb tone los yog nruab nrab tone ntom ntau. Nyob rau tib lub sij hawm, kuj yuav tsum tau siv ib tug sib sib zog nqus thiab lengthened dub version ntawm qib los ntxiv.

 

(5) cov ntaub ntawv tuab tuab

Ib phau ntawv tuab, npub nrog qhov ntom ntom ntom ntawm {{0}}.5 lossis ntau dua, lossis txawm tias 1.0. Vim tsis txaus los yog kev loj hlob, feem ntau ntawm cov theem tsaus nti ntawm daim duab ntog rau ntawm tus ntiv taw ntawm tus yam ntxwv tsis zoo nkhaus thiab qis dua ib nrab ntawm txoj kab ncaj nraim. Qhov tseem ceeb ntawm cov ntawv sau zoo li no yog qhov tsaus thiab tob, ntawm 2 thiab 3 qib ntawm cov txheej txheem tshiab ci ntsa iab. Qhov ci ntsa iab yog tsawg, theem nruab nrab ntawm lub suab tsaus yog nplua nuj thiab qib yog mos, thiab thaj tsam piv yog loj heev. Lub suab tseem ceeb kuj poob rau hauv thaj tsam ntawm qhov nruab nrab ceev. Qhov ntom ntom ntawm cov xim dub thiab dawb daim teb calibration yuav tsum loj dua, theem nkhaus ntawm nruab nrab thiab tsaus lub suab yuav tsum tau txo qis me ntsis, thiab theem nruab nrab thiab lub suab nrov nrog rau lub suab nrov yuav tsum ci dua, thiaj li ua tiav cov suab nrov zoo sib xws. thiab pom kev ci ntsa iab.

 

(6) Kev faib tawm theem nrab ntawm cov ntawv sau sib txawv

Qee cov ntawv sau nrog qhov nruab nrab thiab qhov sib txawv ntawm qhov sib txawv siab muaj tsawg dua cov suab nruab nrab thiab qhov sib txawv loj dua, thaum lub suab siab thiab qis qis dua yog maj thiab maj. Piv txwv li, xim zaj duab xis tua nyob rau hauv backlight, qhov ntau lawm yuav tsum sim ua kom lub teeb thiab ntxoov ntxoo ntawm lub ntsiab lub suab ntawm no hom ntawm cov duab ua hauj lwm, thiaj li mus cuag tau zoo dua cov nyhuv.

 

Qhov loj ntawm cov duab theem sib piv, uas tuaj yeem hloov kho rau qhov ntom ntom ntau compression thaum luam. Qhov pib ntom ntom kuj tseem tuaj yeem hloov pauv los ntawm kev kho cov ntsiab lus ceev thiab sau cov chaw teeb tsa. Qhov sib txawv ntawm cov ntawv sau sib txawv yog qhov sib txawv heev, thiab cov xim luam ntawv yuav tsum tau ua dua tshiab raws li qhov sib txawv ntawm qhov sib txawv ntawm daim duab, qhov ntom ntom yog feem ntau qis dua cov ntawv sau xim, thaum xim sib cais phaj, nws yuav tsum tau compressed thiab kho.

 

Qhov ntom ntom ntawm cov ntaub ntawv luam tawm yog qhov loj, uas tuaj yeem tsis tsuas yog rov ua dua qee qib ntawm cov ntawv sau qub lossis cov duab qub, tab sis kuj ua rau qhov sib txawv ntawm cov qib qhib qee qhov, thiab qhov kev nkag siab ntawm peb sab muaj zog. Hauv particular, nws tuaj yeem txhim kho qhov sib txawv ntawm qhov sib txawv, tab sis kuj txhim kho lub ntsiab lus ntawm qib duab. Ntawm qhov tod tes, kuj ua rau cov duab xim qhib cov qib, sib sib zog nqus saturation, lub teeb pom kev. Txawm li cas los xij, qhov nce ntawm qhov ntom ntawm luam ntawv number case txheej yog contradictory rau qhov nce ntawm dot. Nws yog tsis yooj yim sua kom ncav cuag lub siab ceev ntawm cov xim pob tshab zaj duab xis.

 

Tsuas yog nyob rau hauv cov xwm txheej zoo ntawm kev lag luam tsim nyog ntawm daim ntawv, tus cwj mem thiab cov khoom siv thiab cov ntawv luam tawm, tuaj yeem muaj qhov qis dua nce tus nqi thiab ntau dua ntom ntom ntawm number case txheej. Lub hom phiaj txheej txheem txheej txheem los txiav txim siab qhov ntsuas zoo Densitometer los ntsuas cov tshuab luam ntawv ntawm txhua lub tshuab luam ntawv txheej, thiab xam nws cov nqi luam ntawv K. Thaum tus nqi no siab (daj version 0.3 ~ 0.4, magenta thiab ntsuab version 0.4 ~ 0.55, dub version {{9} } .5 ~ {{{0. 6), lawv txoj kev sib cav sib luag yog qhov siab, thiab cov ntawv luam tawm zoo dua. Yuav kom txuag tau tus number case, qee cov neeg tawm tswv yim txo qhov ceev ntawm cov luam ntawv number case los txo qhov nce ntawm cov dot, tab sis qhov no yuav txo cov theem ntawm cov duab darkening kawg txheej, tag nrho cov qib sib piv tsis yog siab tshaj, kuj tsis tuaj yeem ncav cuag. qhov zoo tshaj plaws qib qib luam ntawv luam tawm.

 

Vim tias cov txheej txheem luam ntawv tsis yog hloov pauv hloov pauv, kev them nyiaj yuav tsum tau ua ua ntej luam ntawv. Txhawm rau ua kom haum rau cov txheej txheem luam ntawv, peb lub dot dhia zones ntawm kev luam ntawv yuav tsum tau hloov kho, uas yog, thaj tsam ntawm 3%, 50% thiab 80%. Vim tias 3% cov ntsiab lus me me yooj yim plam, yuav cuam tshuam cov xim ntawm thaj chaw tseem ceeb, 50% dot cheeb tsam yooj yim nce, yuav cuam tshuam rau nruab nrab lub suab, cov cim tshwj xeeb ntawm daim tawv nqaij hloov xim. 80% dot cheeb tsam yog ib qho yooj yim rau qib, yuav cuam tshuam rau theem ntawm lub suab tsaus, tshwj xeeb tshaj yog cov xim tseem ceeb ntawm lub suab tsaus thiab qhov tob ntawm qib xim thawj, yog li luam ntawv tsis yooj yim rau coj mus rau hauv tus account ob qho tib si. Yog li ntawd, cov xim tseem ceeb thiab qhov tseem ceeb ntawm cov ntawv sau tseem ceeb yuav tsum raug kho kom tsis txhob muaj peb qhov chaw dhia no.

 

Plaub. Lub ntsiab txhais ntawm cov ntawv sau thiab txoj kev kho mob

(1) Lub firmness ntawm contour ntawm daim duab hierarchy

Ua ntej ntawm tag nrho cov, cov khoom (piv txwv li, sharpness) ntawm ciam teb ntawm cov ntawv sau qib yog lub hauv paus. Nyob rau hauv tag nrho cov txheej txheem ntawm kev yug me nyuam, qhov kev hloov dav ntawm cov duab txheej ciam teb yuav tsum tau nthuav dav ib kauj ruam, tshwj xeeb tshaj yog qhov loj thiab me me. Tus ciam teb firmness yog tsis rov qab los. Lub sharpness ntawm cov qib luam ciam teb tsuas zoo nkaus li accentuated los ntawm cov xim sib cais.

 

(2) Clarity ntawm qhov sib txawv hloov ntawm ob txheej nyob ib sab ntawm daim duab

Yog hais tias qhov sib txawv ntom ntom ntawm cov khaubncaws sab nraud povtseg loj, qhov pom kev pom tau meej. Cov ciam teb sib txawv tuaj yeem hais meej nyob rau hauv cov xim sib cais los tsim qhov illusion ntawm kev txhim kho, thiab qhov sib txawv ntawm cov qib hloov maj mam tuaj yeem txhim kho tau zoo.

 

(3) kev daws teeb meem ntawm cov ntawv sau qub lossis qib duab luam tawm

Nws hu ua kev ntxhib los mos. Cov ntaub ntawv luam tawm yog raws li qhov kev daws teeb meem ntawm cov qib zoo ntawm cov duab qub, tab sis nws cuam tshuam los ntawm kev daws teeb meem ntawm lub phaj optics, magnification, thickness ntawm lub network cable thiab plaub-xim phaj. Tom qab cov txheej txheem ua phaj, theem ntawm kev nthuav dav ntawm cov ntawv sau qub tsis tuaj yeem rov qab los.
