Tom qab ntau tshaj li kaum xyoo ntawm txoj kev loj hlob, technology ntawm rooj teeb layout tsim tau hloov hom kev ua hauj lwm tsim ntawm cov qauv tsim thiab teeb lub teeb tsa yav dhau los, thiab hloov nws nrog lub computer screen ua haujlwm. Lub computer screen tsis tsuas yog qhia cov qauv ntawm qhov qauv tsim, tab sis kuj yog xim. Txawm li cas los xij, ntau tus neeg uas muaj lub vijtsam feem ntau xav tias cov xim uas lawv tab tom pom muaj feem ntau ntawm cov khoom luam tawm. Qhov chaw npo yuav muab tsim tawm rau hauv xovxwm. Kuv ntseeg tias qhov no yog ib qho kev paub tsis meej rau ntau tus nyeem. Lub sij hawm no kuv yuav daws tau qhov kev paub no rau txhua tus neeg.
Yog tias koj xav siv lub vijtsam los saib cov xim uas luam tawm rau yav tom ntej, peb yuav tsum tau saib xyuas thiab tswj cov ntsiab lus hauv qab no;
(1) muaj qhov tsim nyog thiab ruaj khov xim,
(2) Qhov screen tau muab kev kho kom zoo,
(3) ICC Profile nrog tsim nyog luam ntawv lossis pov thawj.
Screen calibration txhais
Yav tag los, ntau tus neeg tau hais tias qhov tshuaj ntsuam calibration yog kho qhov screen kom zoo li cov teeb meem luam tawm. Qhov kev xyaum no yog siv cov ntawv sau ua ib qho qauv siv thiab siv cov software xws li Gamma muab los ntawm tsev av los yog siv ncaj qha. Cov kev hloov kho ntawm cov zaub kom ua kom muaj xim zoo ib yam li los yog tib xim thaum luam. Tab sis qhov no yog ib txoj kev uas tsis muaj ICC haujlwm ua ntej, txoj kev no tsuas yog ua tiav lub hom phiaj ntawm qhov kev tsim, lossis nws yuav tsis yog tib qhov tshwm sim rau txhua qhov software. Qhov loj tshaj plaws yog tias tsis muaj kev tswj hwm hauv nruab nrab los koom ua ke rau xim, yog li ntawd Apple tau tsim ib qhov kev pab ntxiv hu ua ColorSY uas yog ob peb xyoos dhau los. Qhov no yog rab peev xwm siv lub tshuab software rau kev tswj xim xim, tab sis qhov kev tswjfwm hauv tsev yuav tsum tau qee cov ntaub ntawv ntsig txog cov yam ntxwv ntawm cov khoom siv sib txawv. Cov ntaub ntawv no hu ua ICC Profiles, thiab tiam dhau ntawm cov ICC cov ntaub ntawv xav tau kev kho vaj tse thiab software tsim nyog.
Thawj txoj hauj lwm ntawm kev tshuaj xyuas calibration
Screen calibration yuav muab faib ua ob seem. Thawj yog qhov chaw tswj. Vim tias qhov vijtsam yog ib qho kev sib txuas, cov nplaim ntawm lub vijtsam yog los ntawm lub teeb nyob ib puag ncig, xws li thaum lub teeb ntawd ncaj qha ntawm qhov screen. Lub sib piv ntawm daim duab yuav ua rau lub sijhawm tiag. Yog vim li cas yog hais tias lub teeb nyob rau hauv lub chav yog thaws rov los ntawm lub iav ntawm daim duab tube, thiaj li hais tias dub feem yuav tsis tsim txaus dub. Yog hais tias qhov teeb muaj nyob hauv tsev raug kaw, qhov sib txawv ntawm lub vijtsam dheev qeeb, tab sis kuv ntseeg tias tsis muaj leej twg nyiam ua hauj lwm hauv cheeb tsam dub, ua rau cov neeg ua haujlwm tsis xis nyob. Ib txoj hau kev zoo yog kom tswj cov teeb pom kev zoo hauv chav tsev kom lub teeb tsis tuaj yeem ci rau hauv daim duab tube khob. Ib txoj hauv kev zoo tshaj yog ntxiv kom muaj qhov sib txuam ib qho rau lub vijtsam.
Nyob ruaj ruaj thiab txheem teeb pom kev zoo
Tsuas yog hais tias lub teeb nyob rau hauv chav tsev kom tswj kom lub sib piv ntawm qhov screen tau zoo tshwm sim, tab sis ntau cov phooj ywg yuav las mees lub illumination ntawm tus thawj. Thaum peb tswj lub teeb tsis tuaj yeem tsis pom qhov screen, lub teeb rau ntawm ob tog ntawm qhov screen tsis txaus, thiab xim kub Tsis pub, yog li nws yog qhov zoo tshaj plaws kom muaj kev ruaj khov thiab nyeem ntawv lub teeb lub thawv. Lub teeb lub thawv no feem ntau yog qhov tsim los, feem ntau tus qauv thoob ntiaj teb 5000K xim, thiab lub teeb pom kev zoo tsis ua rau xav txog, thiab lub teeb pom kev yog qhov nruab nrab.
Xim kub
Cov xim kub yog siv los mus saib cov ntaub ntawv uas lub teeb xim dawb kuj kom muaj nuj nqis rau xim qhov muag pom ntawm lub teeb ci. Raws li kev tshawb xav, tus txheej txheem dub dub nrog lub cev nqus thiab hluav taws xob muaj peev xwm rhaub, thiab kub kub nce. Qhov kub ntawm lub cev dub yog rhuab mus rau qhov kub thiab txias thaum lub teeb ci nyob ze rau lub teeb ci, uas yog txhais tias yog qhov sib xyaw xim kub ntawm lub teeb ci. , raug xa mus rau raws li cov xim kub, rau qhov tsis sov K (Kelvin, los yog Kelvin kub) raws li ib chav tsev.
Qhov sib dua hauv cov xim, qhov kub dua qhov xim; Yog tias nws yog liab, txo cov xim kub. Thaum nruab hnub, lub teeb xim ntawm lub hnub kuj hloov nrog lub sijhawm; nyob rau hauv 40 feeb tom qab hnub tuaj, xim xim yellower thiab xim kub 3000K; lub hnub thaum tsaus ntuj yog dawb, nce mus rau 4800 ~ 5800K, thiab hnub zoo li yog txog 6500K thaum tav su; lub teeb xim yog xim liab ua ntej hnub poob. Cov xim kub poob rau li 2200K. Nyob rau hauv qhov tsim teeb ci, muaj tungsten lub teeb qij 2000 ~ 3400K, qhov dav ntawm lub teeb beige teeb 2600 ~ 4000K, cov teeb dawb lub teeb 6000 ~ 8000K, thiab peb tsim luam kev lag luam xav tau 5000K txheem xim lub teeb xim.
Vim li cas koj ho muaj tus qauv ntxoov ntxoo? Vim yog lub 5000K xim kub qhov chaw.
(1) nyob nruab nrab ntawm cov spectrum pom,
(2) Nws yog lub teeb dawb uas muaj xim zoo.
