S pr\u00edchodom telev\u00edzorov 4K UHD potrebovali v\u00fdrobcovia sp\u00f4sob, ako zobrazova\u0165 obsah s ni\u017e\u0161\u00edm rozl\u00ed\u0161en\u00edm na celej obrazovke. Bez upscalingu by obrazy s ni\u017e\u0161\u00edm rozl\u00ed\u0161en\u00edm zaberali iba \u010das\u0165 obrazovky alebo by boli zv\u00e4\u010d\u0161en\u00e9 so zn\u00ed\u017eenou ostros\u0165ou. To viedlo k v\u00fdvoju r\u00f4znych technol\u00f3gi\u00ed upscalingu ur\u010den\u00fdch na prisp\u00f4sobenie Full HD a \u010fal\u0161\u00edch videoform\u00e1tov s ni\u017e\u0161\u00edm rozl\u00ed\u0161en\u00edm UHD displejom.<\/p>\n\n\n\n

V roku 2015 spolo\u010dnos\u0165 Samsung predstavila technol\u00f3giu Remastering Engine<\/strong>, ktor\u00e1 bola ur\u010den\u00e1 na zlep\u0161enie vzh\u013eadu obsahu s ni\u017e\u0161\u00edm rozl\u00ed\u0161en\u00edm na UHD telev\u00edzoroch. Pojem Remastering Engine<\/strong> v\u0161ak nebol pre spotrebite\u013eov okam\u017eite zrozumite\u013en\u00fd. V roku 2016 Samsung tento pojem nahradil jednoduch\u0161\u00edm n\u00e1zvom UHD Upscaling<\/strong>. Nov\u00fd n\u00e1zov priamo sp\u00e1jal dva k\u013e\u00fa\u010dov\u00e9 pojmy \u2014 UHD<\/strong> a upscaling<\/strong> \u2014 v\u010faka \u010domu bolo jednoduch\u0161ie pochopi\u0165 \u00fa\u010del tejto technol\u00f3gie.<\/p>\n\n\n\n

Z\u00e1kladn\u00fd princ\u00edp zostal nezmenen\u00fd. Telev\u00edzor prijme obraz s ni\u017e\u0161\u00edm rozl\u00ed\u0161en\u00edm a spracuje ho tak, aby zodpovedal vy\u0161\u0161iemu rozl\u00ed\u0161eniu UHD displeja.<\/p>\n\n\n\n

Ako funguje upscaling<\/strong><\/h2>\n\n\n\n

Upscaling prev\u00e1dza video s ni\u017e\u0161\u00edm rozl\u00ed\u0161en\u00edm do form\u00e1tu vhodn\u00e9ho pre displej s vy\u0161\u0161\u00edm rozl\u00ed\u0161en\u00edm. Nedok\u00e1\u017ee obnovi\u0165 detaily, ktor\u00e9 v p\u00f4vodnom videu nikdy neboli, ale m\u00f4\u017ee sp\u00f4sobi\u0165, \u017ee obraz bude na UHD obrazovke p\u00f4sobi\u0165 ostrej\u0161ie a plynulej\u0161ie.<\/p>\n\n\n\n

Obraz Full HD<\/strong> m\u00e1 rozl\u00ed\u0161enie 1 920 \u00d7 1 080<\/strong>, teda 2 073 600 pixelov<\/strong>.<\/p>\n\n\n\n

UHD<\/strong> displej m\u00e1 rozl\u00ed\u0161enie 3 840 \u00d7 2 160<\/strong>, teda 8 294 400 pixelov<\/strong>.<\/p>\n\n\n\n

UHD displej preto obsahuje \u0161tyrikr\u00e1t viac pixelov ako obraz Full HD.<\/p>\n\n\n\n

Ke\u010f sa obsah Full HD zobrazuje na UHD telev\u00edzore, telev\u00edzor mus\u00ed vytvori\u0165 \u010fal\u0161ie pixely, aby vyplnil cel\u00fa obrazovku. Tento proces sa ozna\u010duje ako upscaling<\/strong>.<\/p>\n\n\n\n

Najjednoduch\u0161\u00ed pr\u00edstup spo\u010d\u00edva v duplikovan\u00ed existuj\u00facich pixelov, \u010do v\u0161ak m\u00f4\u017ee vies\u0165 k blokovit\u00e9mu obrazu, zubat\u00fdm okrajom a vidite\u013en\u00fdm artefaktom. Modern\u00e9 telev\u00edzory namiesto toho pou\u017e\u00edvaj\u00fa algoritmy spracovania obrazu, ktor\u00e9 analyzuj\u00fa p\u00f4vodn\u00e9 pixely a oblasti okolo nich, aby vypo\u010d\u00edtali hodnoty \u010fal\u0161\u00edch pixelov.<\/p>\n\n\n\n

Procesor m\u00f4\u017ee tie\u017e analyzova\u0165 hrany, text\u00fary, kontrast a \u010fal\u0161ie vlastnosti obrazu<\/strong>, aby zlep\u0161il v\u00fdsledok. Modern\u00fd upscaling teda nie je len zv\u00e4\u010d\u0161ovanie obrazu \u2014 kombinuje konverziu rozl\u00ed\u0161enia so zlep\u0161en\u00edm obrazu.<\/p>\n\n\n\n

V\u00fdsledkom m\u00f4\u017ee by\u0165 obsah po upscalingu s plynulej\u0161\u00edmi prechodmi, ostrej\u0161\u00edmi hranami a men\u0161\u00edm po\u010dtom vidite\u013en\u00fdch artefaktov<\/strong> v porovnan\u00ed s obrazom zv\u00e4\u010d\u0161en\u00fdm jednoduch\u00fdm duplikovan\u00edm pixelov.<\/p>\n\n\n\n

\u00daloha modern\u00fdch procesorov<\/strong><\/h2>\n\n\n\n

Ke\u010f sa objavili prv\u00e9 UHD telev\u00edzory, ich procesory boli ove\u013ea menej v\u00fdkonn\u00e9 ako procesory pou\u017e\u00edvan\u00e9 v modern\u00fdch telev\u00edzoroch. Dne\u0161n\u00e9 telev\u00edzne procesory dok\u00e1\u017eu vykon\u00e1va\u0165 ove\u013ea komplexnej\u0161iu anal\u00fdzu a spracovanie obrazu. Algoritmy upscalingu s\u00fa tie\u017e priamo integrovan\u00e9 do syst\u00e9mu spracovania telev\u00edzora, \u010do umo\u017e\u0148uje telev\u00edzoru automaticky konvertova\u0165 obsah s ni\u017e\u0161\u00edm rozl\u00ed\u0161en\u00edm tak, aby zodpovedal rozl\u00ed\u0161eniu obrazovky.<\/p>\n\n\n\n

Tieto mo\u017enosti spracovania pom\u00e1haj\u00fa zni\u017eova\u0165 artefakty, ktor\u00e9 m\u00f4\u017eu vznikn\u00fa\u0165 pri zobrazovan\u00ed obsahu s n\u00edzkym rozl\u00ed\u0161en\u00edm na paneli s vysok\u00fdm rozl\u00ed\u0161en\u00edm, a m\u00f4\u017eu zlep\u0161i\u0165 celkov\u00fd vzh\u013ead obrazu.<\/p>\n\n\n\n

Tento pojem m\u00f4\u017ee by\u0165 trochu zav\u00e1dzaj\u00faci, preto\u017ee samotn\u00fd upscaling vykon\u00e1va procesor telev\u00edzora pomocou \u0161pecializovan\u00fdch algoritmov integrovan\u00fdch v syst\u00e9me.<\/p>\n\n\n\n

Na procese sa v\u0161ak m\u00f4\u017eu podie\u013ea\u0165 modely zalo\u017een\u00e9 na umelej inteligencii. M\u00f4\u017eu napr\u00edklad pom\u00e1ha\u0165 identifikova\u0165 typ zobrazovan\u00e9ho obsahu \u2014 napr\u00edklad \u0161port, pr\u00edrodu alebo \u013eud\u00ed \u2014 a ur\u010di\u0165, ktor\u00e9 algoritmy spracovania obrazu s\u00fa pre dan\u00fd typ sc\u00e9ny najvhodnej\u0161ie.<\/p>\n\n\n\n

Samsung v s\u00fa\u010dasnosti ozna\u010duje svoju technol\u00f3giu ako AI Upscaling<\/strong> a vysvet\u013euje ju formul\u00e1ciou: \u201eAI Upscaling pou\u017e\u00edva vzorce zalo\u017een\u00e9 na umelej inteligencii.\u201c<\/strong><\/p>\n\n\n\n
