Vim li cas cov Broadcast Monitors thiaj li xav tau kev kho xim?
Cov saib xyuas kev tshaj tawm ua haujlwm ua cov khoom siv tseem ceeb thoob plaws kev thaij duab video, kev ntsuas xim tom qab thiab kev ua haujlwm tshaj tawm, lub hom phiaj yog kom ua tiav qhov tseeb ntawm cov duab rov qab los ntawm "yam koj pom yog yam koj tau txais". Cov vaj huam sib luag tso saib yeej ib txwm raug kev hloov pauv ntawm cov xim, qhov kaj thiab qhov grey vim lub sijhawm ua haujlwm, kev hloov pauv kub thiab cov khoom siv laus. Yog tsis muaj kev ntsuas tsis tu ncua, qhov yuam kev pom yuav tshwm sim hauv kev saib xyuas ntawm qhov chaw teeb tsa thiab kev ntsuas xim tom qab tsim khoom.
Thaum cov haujlwm kawg raug tso tawm hauv TVs lossis cov platform streaming, cov teeb meem xws li xim tsis sib xws, qhov kaj tsis sib npaug thiab cov xim tawv nqaij tsis sib xws yuav tshwm sim, ua tsis tau raws li cov qauv tshaj tawm thiab ua rau rov ua haujlwm lossis kev tshuaj xyuas tsis ua haujlwm. Lub caij no, kev kho kom raug raws li tus qauv ua kom muaj kev sib xws ntawm cov xim hauv kev koom tes ua pab pawg thiab kev saib xyuas ntau yam khoom siv, zam kev ua yuam kev xim sib sau ua ke hauv tag nrho cov khoom tsim tawm.
Cov Qauv Ntsuas Tseem Ceeb rau Cov Saib Xyuas Kev Tshaj Tawm.
Kev ntsuas qhov ntsuas ntawm cov xov tooj cua tshaj tawm ua raws li cov lus qhia txog kev lag luam tshaj tawm thoob ntiaj teb thiab cov qauv hauv tsev nrog cov qauv tseem ceeb thiab meej.
Ua ntej, rau qhov chaw xim, SD / HD tshaj tawm cov xwm txheej siv Rec.709, 4K / 8K UHD cov xwm txheej siv Rec.2020, thiab kev tsim yeeb yaj kiab yog sib xws nrog DCI-P3 gamut.
Qhov thib ob, rau qhov tseeb ntawm xim, qhov sib txawv ntawm cov xim tseem ceeb ΔE tus nqi yuav tsum tsawg dua 2, thiab cov khoom siv tshaj lij saum toj kawg nkaus ncav cuag ΔE <1.5 nrog kev hloov pauv xim tsis pom rau tib neeg lub qhov muag; qhov yuam kev xim sib sau ua ke ntawm tag nrho cov kev sib txuas tshaj tawm yog capped ntawm 1.0.
Qhov thib peb, rau qhov ci ntsa iab thiab qib dub, qhov ci ntsa iab txheem ntawm HD monitors yog 300cd / ㎡, qhov ci ntsa iab siab tshaj plaws ntawm UHD monitors yog ≥500cd / ㎡, thiab qhov ci ntsa iab qib dub yog ≤0.01cd / ㎡ kom ntseeg tau tias cov ntsiab lus ntawm cov duab ntxoov ntxoo thiab ua tiav cov txheej txheem tseem ceeb.
Qhov thib plaub, rau qhov greyscale thiab gamma, nws ua raws li cov kab gamma tshaj tawm ruaj khov nrog cov xim grey sib xws thiab tsis muaj kev ntxub ntxaug, ua raws li cov qauv tsim thiab tshaj tawm UHD TV. Tsis tas li ntawd, kev kho kom raug txhawb nqa kho vajtse LUT mapping los xauv cov xim ntawm qib kho vajtse rau cov duab tso tawm ruaj khov thiab sib koom ua ke.
Qhov Sib Txawv ntawm Xim Tseem Ceeb ntawm Cov Saib Xyuas Kev Tshaj Tawm thiab Cov Zaub rau Cov Neeg Siv Khoom.
Qhov sib txawv tseem ceeb yog nyob rau hauv lawv qhov chaw: cov saib xyuas kev tshaj tawm xov xwm tseem ceeb duaqhov tseeb ntawm xim, thaum cov khoom siv rau cov neeg siv khoom tseem ceeb duakev pom kev, nrog peb qhov sib txawv tshwj xeeb.
Ua ntej, kev xav txog xim sib txawv. Cov saib xyuas kev tshaj tawm ua raws li qhov tseeb tiag tiag yam tsis muaj kev txhim kho xim lossis kev txhim kho saturation, rov qab kho 100% ntawm cov ntaub ntawv xim qub. Cov neeg siv khoom tso saib (khoos phis tawj, TV hauv tsev) cia li ua kom cov duab ci ntsa iab, ua kom saturation ntau dua thiab ua kom cov xim ntse dua los txhim kho kev saib kev lom zem, ua rau muaj kev cuam tshuam xim hauv zos.
Qhov thib ob, qhov tseeb sib txawv thiab ruaj khov. Txhua lub monitor tshaj tawm yog lub Hoobkas-calibrated ib qho los ntawm ib qho thiab txhawb nqa kev kho vajtse tsis tu ncua nrog tus nqi qis heev ΔE thiab lub sijhawm ntev ruaj khov, gamut thiab grayscale. Cov neeg siv khoom tso saib tsuas yog txhawb nqa kev hloov kho gamut yooj yim yam tsis muaj cov txheej txheem calibration kev tshaj lij, muaj qhov sib txawv xim loj, qhov tsis zoo ntawm cov xim screen thiab kev hloov pauv xim ntev.
Qhov thib peb, cov xwm txheej siv sib txawv. Cov khoom siv tshaj tawm pabcuam kev tsim khoom thiab kev tshaj tawm, ua raws li cov qauv tshaj tawm kom ntseeg tau tias muaj cov zis sib xws thoob plaws ntau lub platform. Cov khoom siv rau cov neeg siv khoom tsuas yog rau kev lom zem hauv chaw ua haujlwm txhua hnub thiab kev lom zem suab-pom tsis muaj cov lus qhia xim sib koom ua ke, ua rau muaj qhov sib txawv loj ntawm cov khoom siv tib yam ntawm cov khoom siv sib txawv, yog li lawv tsis tuaj yeem siv ua cov ntaub ntawv tsim khoom.
