HDR ine hukama hwakasimba nekupenya. Iyo HDR ST2084 1000 standard inozadzikiswa zvizere kana ikashandiswa pamasikirini anokwanisa kuwana kupenya kwepamusoro pe1000 nits.

Padanho rekupenya rema nits zana, basa reST2084 1000 electro-optical transfer rinowana chiyero chakanaka pakati pekuona kwevanhu uye kugona kwetekinoroji, izvo zvinoita kuti pave nekushanda kwakanaka kwemhando yepamusoro ye dynamic range (HDR).

Uyezve, mamonita ane kupenya kwakanyanya kwe 1000 nits anogona kushandisa zvizere maitiro e ST2084 curve's logarithmic encoding. Izvi zvinobvumira kudzokororwa kwakarurama kwe specular highlights uye mhedzisiro yezuva inosvika padanho rechokwadi rehukuru, uye zvakare kuchengetedza ruzivo rwemumvuri munzvimbo dzine rima. Kuwedzera kwe dynamic range kunobvumira mifananidzo kugona 1000 nits HDR kuitira kuti iratidze magadzirirwo nema gradients angadai akamanikidzwa kana kurasikirwa mumamiriro ekunze asina kupenya.

Muganho we1000 nits unotsanangura nzvimbo inokosha yekushandiswa kweHDR ST2084 1000 content. Inopa kupenya kwakakwana kuti ipe huwandu hunoshamisa hwe contrast hweanopfuura 20,000:1 kana ikabatanidzwa ne OLED-level black depth. Pamusoro pezvo, 1000 nits inoramba iri pasi pemiganhu inoshanda ye tekinoroji yekuratidzira yevatengi uye kushandiswa kwesimba kana paine kushanda kwepamusoro. Kuenzana uku kunovimbisa kuti chinangwa chehunyanzvi chevatungamiriri chinochengetedzwa ukuwo zvichipawo vashandisi ruzivo rwakasununguka rwekuona.

Pavanenge vachinyatsoongorora mifananidzo yeST2084, mastudio ehunyanzvi anowanzo shandisa mamonita ekugadzira e1000 nits sezvo asingakwanise kutakura akawanda magadzirirwo ekuona chaiwo asiwo anovimbisa kuti anoenderana nekutarisa kwechiedza chisina kujeka kuburikidza ne toni mapping. Mugumisiro wekupedzisira iHDR picture iyo inoramba ichishanda zvakanaka pamidziyo yakawanda pasina kukanganisa maonero emugadziri wefirimu.
