HDR muaj feem cuam tshuam nrog qhov ci ntsa iab. Tus qauv HDR ST2084 1000 raug lees paub tag nrho thaum siv rau ntawm cov ntxaij vab tshaus uas muaj peev xwm ua tiav qhov ci ntsa iab siab tshaj plaws 1000 nits.

Ntawm qib ci ntsa iab 1000 nits, ST2084 1000 electro-optical transfer function pom qhov sib npaug zoo tagnrho ntawm kev pom kev ntawm tib neeg thiab kev muaj peev xwm siv thev naus laus zis, uas ua rau muaj kev ua tau zoo heev (HDR).

Tsis tas li ntawd xwb, cov saib uas muaj 1000 nits ci ntsa iab yuav siv tau tag nrho cov yam ntxwv ntawm ST2084 curve's logarithmic encoding. Qhov no tso cai rau kev rov ua dua qhov tseeb ntawm cov specular highlights thiab cov teebmeem ntawm lub hnub ci uas ze rau qhov tseeb ntawm lub ntiaj teb, thiab tseem khaws cov duab ntxoov ntxoo hauv qhov chaw tsaus ntuj. Qhov ntau ntxiv dynamic tso cai rau cov duab mastering rau 1000 nits HDR kom tso saib cov textures thiab gradients uas yuav raug compressed lossis ploj hauv qhov xwm txheej qis dua.

Qhov 1000 nits threshold txhais tau tias qhov chaw zoo tshaj plaws rau HDR ST2084 1000 cov ntsiab lus siv. Nws muab qhov ci ntsa iab txaus kom muab qhov sib piv zoo kawg nkaus ntawm ntau dua 20,000: 1 thaum ua ke nrog OLED-level dub tob. Tsis tas li ntawd, 1000 nits tseem nyob hauv qab qhov txwv ntawm cov neeg siv khoom siv thev naus laus zis thiab kev siv hluav taws xob hauv qhov xwm txheej ntawm kev ua tau zoo siab. Qhov sib npaug no lav tias cov thawj coj lub hom phiaj kos duab tseem khaws cia thaum tseem muab cov neeg siv nrog kev paub saib zoo.

Thaum tswj cov duab ST2084, cov chaw tsim khoom tshaj lij feem ntau siv cov saib xyuas kev tsim khoom 1000 nits vim tias lawv tsis haum rau feem ntau ntawm cov chaw saib tiag tiag tab sis kuj ua kom muaj kev sib raug zoo nrog cov saib xyuas qhov kaj qis dua los ntawm kev kos duab suab. Qhov kawg yog daim duab HDR uas khaws nws qhov cuam tshuam pom ntawm ntau yam khoom siv yam tsis muaj kev cuam tshuam rau tus neeg ua yeeb yaj kiab lub zeem muag.

Thaum kawg, kev sib xyaw ua ke ntawm 1000 nits zaub muaj peev xwm thiab ST2084 1000 tus qauv yog qhov saum toj kawg nkaus ntawm HDR kev siv tam sim no, muab rau cov neeg saib nrog kev paub txog kev pom uas txuas qhov sib txawv ntawm cov ntsiab lus digital thiab kev pom ntawm tib neeg.
