Existuj\u00fa dva koncepty TruMotion:<\/p>\n\n\n\n
\n
TruMotion ako marketingov\u00fd trik od LG<\/strong>: TruMotion je term\u00edn vytvoren\u00fd spolo\u010dnos\u0165ou LG, ktor\u00fd m\u00e1 prezentova\u0165 telev\u00edzory v priaznivej\u0161om svetle, ne\u017e ak\u00e9 v skuto\u010dnosti s\u00fa. V podstate ide o falo\u0161n\u00fd technick\u00fd parameter, ktor\u00fd nezodpoved\u00e1 skuto\u010dnej obnovovacej frekvencii obrazovky.<\/li>\n\n\n\n
TruMotion ako nastavenie spracovania obrazu<\/strong>: TruMotion je tie\u017e nastavenie v telev\u00edzoroch LG, ktor\u00e9 aktivuje \u010fal\u0161ie algoritmy spracovania obrazu.<\/li>\n<\/ol>\n\n\n\n
TruMotion ako marketingov\u00e9 nastavenie<\/strong><\/h2>\n\n\n\n
TruMotion je ozna\u010denie v \u0161pecifik\u00e1ci\u00e1ch, ktor\u00e9 pou\u017e\u00edva LG na vytvorenie il\u00fazie vysokej obnovovacej frekvencie. P\u00f4vodne sa tento parameter meral v hertzoch a be\u017ene sa pou\u017e\u00edvali hodnoty v rozsahu 300-400 Hz. S \u010dasom sa za\u010dali u\u017e\u00edvatelia p\u00fdta\u0165 na tieto vysok\u00e9 \u010d\u00edsla a LG opustilo tieto ve\u013ek\u00e9 hodnoty. V s\u00fa\u010dasnosti \u0161pecifik\u00e1cie telev\u00edzorov \u010dastej\u0161ie uv\u00e1dzaj\u00fa 120 alebo 240 Hz pre Severn\u00fa Ameriku a 100 (200) Hz pre Eur\u00f3pu a \u010fal\u0161ie regi\u00f3ny. S pr\u00edchodom OLED telev\u00edzorov sa TruMotion transformovalo na ozna\u010denia ako OLED Motion alebo Motion Pro, a v niektor\u00fdch krajin\u00e1ch u\u017e nie je uveden\u00e9 v \u0161pecifik\u00e1ci\u00e1ch.<\/p>\n\n\n
\n
<\/figure>\n<\/div>\n\n\n
V podstate je TruMotion ak\u00fdsi \u201eindex pohybu\u201c. LG tvrd\u00ed, \u017ee t\u00e1to technol\u00f3gia umo\u017e\u0148uje telev\u00edzoru zobrazi\u0165 obraz s kvalitou, ktor\u00e1 vizu\u00e1lne vyzer\u00e1, akoby obnovovacia frekvencia obrazovky zodpovedala hodnote TruMotion. Napr\u00edklad telev\u00edzor s TruMotion 240 by mal vytvori\u0165 dojem, \u017ee sledujete video na 240 Hz. V skuto\u010dnosti to v\u0161ak nie je pravda.<\/p>\n\n\n\n
LG pou\u017e\u00edva relat\u00edvne jednoduch\u00fd princ\u00edp: ak m\u00e1 telev\u00edzor obrazovku s 60 Hz, \u0161pecifik\u00e1cie TruMotion uv\u00e1dzaj\u00fa 120 Hz, a ak je frekvencia obrazovky 120 Hz, TruMotion sa \u201eprepne\u201c na 240 Hz. Ide len o zdvojn\u00e1sobenie skuto\u010dnej obnovovacej frekvencie pre marketingov\u00fd efekt.<\/p>\n\n\n\n
Nastavenia TruMotion na telev\u00edzoroch<\/strong><\/h2>\n\n\n\n
Nastavenie sa objavilo na telev\u00edzoroch u\u017e od za\u010diatku a malo len dve mo\u017enosti: zapn\u00fa\u0165 alebo vypn\u00fa\u0165. Av\u0161ak modern\u00e9 telev\u00edzory, po\u010dn\u00fac rokom 2022, z\u00edskali \u010fal\u0161ie podnastavenia pre TruMotion na presnej\u0161iu prev\u00e1dzku. Je d\u00f4le\u017eit\u00e9 pochopi\u0165, \u017ee TruMotion funguje iba s videami, ktor\u00fdch sn\u00edmkov\u00e1 frekvencia je ni\u017e\u0161ia, ne\u017e ak\u00fa v\u00e1\u0161 telev\u00edzor dok\u00e1\u017ee prehr\u00e1va\u0165. Napr\u00edklad toto nastavenie bude u\u017eito\u010dn\u00e9, ak sledujete video s 30 sn\u00edmkami za sekundu. Ak va\u0161e video m\u00e1 rovnak\u00fa sn\u00edmkov\u00fa frekvenciu ako podporuje v\u00e1\u0161 telev\u00edzor (napr. 60 Hz), TruMotion nebude fungova\u0165, preto\u017ee spracovanie nie je potrebn\u00e9.<\/p>\n\n\n\n
Nasleduj\u00faca tabu\u013eka ukazuje, ak\u00e9 \u010fal\u0161ie mo\u017enosti prisp\u00f4sobenia s\u00fa k dispoz\u00edcii na telev\u00edzoroch vydan\u00fdch po roku 2022:<\/p>\n\n\n\n

Ako funguje TruMotion<\/strong><\/h2>\n\n\n\n
TruMotion pou\u017e\u00edva dve met\u00f3dy na dosiahnutie hlad\u0161ieho obrazu: duplik\u00e1cia sn\u00edmok a vlo\u017eenie \u010diernych sn\u00edmok.<\/p>\n\n\n\n
\n
Duplik\u00e1cia sn\u00edmok<\/strong>: Ak v\u00e1\u0161 telev\u00edzor podporuje 120 Hz a zdrojov\u00e9 video je 60 Hz, ka\u017ed\u00e1 sn\u00edmka bude duplikovan\u00e1, \u010do vytv\u00e1ra dojem hladk\u00e9ho pohybu. Tento sp\u00f4sob m\u00e1 v\u0161ak nev\u00fdhody: ak je sn\u00edmkov\u00e1 frekvencia zdrojov\u00e9ho videa n\u00edzka, vznik\u00e1 takzvan\u00fd \u201esapon\u00e1tov\u00fd efekt\u201c, ke\u010f sa obraz zd\u00e1 pr\u00edli\u0161 hladk\u00fd a neprirodzen\u00fd. To je sp\u00f4soben\u00e9 fyziol\u00f3giou vn\u00edmania: ke\u010f je m\u00e1lo sn\u00edmok, mozog si v\u0161imne medzery medzi nimi a obraz sa zd\u00e1 trhav\u00fd. Ale ke\u010f sa po\u010det sn\u00edmok zv\u00fd\u0161i, obraz sa zd\u00e1 by\u0165 pr\u00edli\u0161 hladk\u00fd.<\/li>\n\n\n\n
Vlo\u017eenie \u010diernych sn\u00edmok<\/strong>: Na odstr\u00e1nenie sapon\u00e1tov\u00e9ho efektu, zn\u00ed\u017eenie nadmernej hladkosti obrazu alebo zn\u00ed\u017eenie trhania medzi sn\u00edmkami sa do\u010dasne vypne podsvietenie obrazovky, \u010d\u00edm sa vytvor\u00ed \u201e\u010dierna sn\u00edmka\u201c. To pom\u00e1ha mozgu r\u00fdchlej\u0161ie \u201evymaza\u0165\u201c predch\u00e1dzaj\u00facu sn\u00edmku z podvedomia, \u010d\u00edm sa zlep\u0161uje vn\u00edmanie pohybu bez nadmernej hladkosti a zni\u017euje sapon\u00e1tov\u00fd efekt.<\/li>\n<\/ol>\n\n\n\n
Falo\u0161n\u00e9 inform\u00e1cie o TruMotion technol\u00f3gii v prv\u00fdch rokoch<\/strong><\/h2>\n\n\n\n
Ke\u010f sa TruMotion prv\u00fdkr\u00e1t objavil, internet bol pln\u00fd dezinform\u00e1ci\u00ed o technol\u00f3gii. Napr\u00edklad ofici\u00e1lne webov\u00e9 str\u00e1nky LG tvrdili, \u017ee TruMotion umo\u017e\u0148uje telev\u00edzorom vytv\u00e1ra\u0165 medzikroky medzi susedn\u00fdmi sn\u00edmkami. Na tento \u00fa\u010del boli vyvinut\u00e9 prezent\u00e1cie, ktor\u00e9 jasne vysvet\u013eovali \u00fadajn\u00fd \u201epracovn\u00fd princ\u00edp\u201c technol\u00f3gie.<\/p>\n\n\n
\n<\/figure>\n<\/div>\n\n\n
To v\u0161ak nezodpovedalo realite. Ak si predstav\u00edme, ak\u00e9 mno\u017estvo v\u00fdpo\u010dtov\u00fdch zdrojov je potrebn\u00e9 na v\u00fdpo\u010det trajekt\u00f3ri\u00ed pohybuj\u00facich sa objektov v dynamickom videu, je jasn\u00e9, \u017ee telev\u00edzory nem\u00f4\u017eu vykon\u00e1va\u0165 tak\u00e9to \u00falohy v re\u00e1lnom \u010dase so svojimi relat\u00edvne slab\u00fdmi procesormi.<\/p>\n\n\n\n
V prv\u00fdch rokoch technol\u00f3gie TruMotion sa o prisp\u00f4soben\u00ed ve\u013ea nehovorilo, hoci softv\u00e9r sa neust\u00e1le vylep\u0161oval. S pr\u00edchodom v\u00fdkonnej\u0161\u00edch procesorov a aktualizovan\u00fdch opera\u010dn\u00fdch syst\u00e9mov mali pou\u017e\u00edvatelia mo\u017enos\u0165 presnej\u0161ie nastavi\u0165 obraz. V d\u00f4sledku toho sa objavili r\u00f4zne modifik\u00e1cie TruMotion:<\/p>\n\n\n\n
\n
TruMotion Pro<\/strong>: S pridan\u00edm funkcie vlo\u017eenia \u010diernych sn\u00edmok. Vylep\u0161en\u00e9 displeje roz\u0161\u00edrili mo\u017enosti TruMotion, \u010d\u00edm sa obraz stal e\u0161te hlad\u0161\u00edm a prirodzenej\u0161\u00edm.<\/li>\n\n\n\n
