ʻO nā ʻōnaehana HDR ka mea hou loa i nā pale LED 

Makemake ʻoe e kūʻai i kahi pale LED a ʻaʻole ʻoe i ʻike i ke koʻikoʻi o ka huaʻōlelo HDR, (High Dynamic Range, no kāna acronym ma ka ʻōlelo Pelekania)?

Mai hopohopo, eia mākou e wehewehe iā ʻoe.ʻO HDR, ma ka pōkole, ka ʻāpana o kāu pale LED ke kuleana no ka hāʻawi ʻana i nā hiʻohiʻona me nā kala ʻoi aku ka ʻoiaʻiʻo a me ka ʻokoʻa kiʻekiʻe.

ʻIke ʻia ka ʻokoʻa e ka ʻokoʻa ma waena o nā keʻokeʻo ʻulaʻula a me nā ʻeleʻele ʻeleʻele e hiki ai i kahi pale LED ke hōʻike, ana ʻia i ka candela no kēlā me kēia mika square (cd / m2): ka mea i kapa ʻia ʻo NITS.

Nui nā ʻano ma HDR, akā aia i kēia manawa ʻelua mau mea pāʻani nui: ʻo ke ʻano Dolby Vision proprietary, a me ka HDR10 maʻamau maʻamau.ʻO Dolby ka mea mua i komo i ka pāʻina me kahi TV prototype hiki ke hōʻike i ka 4,000 nits o ka mālamalama.No ka manawa pōkole, ua like like ʻo Dolby Vision me HDR, akā ʻaʻole makemake nā mea hana a pau e hahai i nā lula o Dolby (a i ʻole e uku i kā lākou uku), a nui ka poʻe i hoʻomaka e hana i kā lākou mau koho ponoʻī.

Hoʻohana nā ʻano HDR nui ʻelua i ka metadata e holo ana ma ka hōʻailona wikiō ma luna o kahi kaula HDMI, metadata e hiki ai i ke wikiō kumu ke“hai aku”he hōʻike LED pehea e hōʻike ai i nā kala.Hoʻohana ʻo HDR10 i kahi ala maʻalahi: hoʻouna ʻo ia i nā metadata i ka manawa hoʻokahi a i ka hoʻomaka ʻana o kahi wikiō, e ʻōlelo ana i kekahi mea e like me, "Ua hoʻopili ʻia kēia wikiō me ka HDR, a pono ʻoe e hana pēlā."

Ua lilo ʻo HDR10 i mea kaulana loa o nā ʻano ʻelua.Ma luna aʻe o nā mea a pau, he kūlana wehe ia: hiki i nā mea hana o nā pale LED ke hoʻokō me ka manuahi.Manaʻo ʻia ʻo ia e ka UHD Alliance, ka mea maʻamau e makemake i nā kūlana wehe i nā ʻano ponoʻī e like me Dolby Vision.
