PQI (Picture Quality Index) je vlastn\u00e9 hodnotenie kvality obrazu spolo\u010dnosti Samsung, ktor\u00e9 sa pou\u017e\u00edvalo v technick\u00fdch \u0161pecifik\u00e1ci\u00e1ch niektor\u00fdch star\u0161\u00edch telev\u00edzorov.

Vy\u0161\u0161ie \u010d\u00edslo PQI nezaru\u010duje lep\u0161iu kvalitu obrazu, preto by si kupuj\u00faci mali overi\u0165 skuto\u010dn\u00e9 technick\u00e9 parametre telev\u00edzora vr\u00e1tane obnovovacej frekvencie a funkci\u00ed spracovania pohybu.<\/p>\n\n\n\n

\u010co znamen\u00e1 PQI v telev\u00edzoroch Samsung<\/strong><\/h2>\n\n\n\n

PQI je intern\u00e9 hodnotenie spolo\u010dnosti Samsung, ktor\u00e9 vyjadruje plynulos\u0165 pohybu. V technick\u00fdch \u0161pecifik\u00e1ci\u00e1ch niektor\u00fdch modelov sa uv\u00e1dza napr\u00edklad ako \u201ePQI 1300\u201c alebo podobn\u00e9 \u010d\u00edslo ved\u013ea rozl\u00ed\u0161enia a podpory HDR.<\/p>\n\n\n\n

Pod\u013ea dostupn\u00fdch spr\u00e1v m\u00f4\u017ee zoh\u013ead\u0148ova\u0165 aj typ panela, rozl\u00ed\u0161enie, jas a kontrastn\u00fd pomer. Vy\u0161\u0161ia hodnota PQI preto nazna\u010duje lep\u0161iu v\u00fdbavu telev\u00edzora v r\u00e1mci vlastn\u00e9ho radu Samsung. Nejde o fyzik\u00e1lne meranie, ako je obnovovacia frekvencia, ani o v\u00fdsledok nez\u00e1visl\u00e9ho testovania.<\/p>\n\n\n\n

Odkia\u013e poch\u00e1dza PQI<\/strong><\/h2>\n\n\n\n

Samsung predstavil PQI v roku 2015 ako n\u00e1stupcu technol\u00f3gie Clear Motion Rate (CMR). Prv\u00e9 hodnotenia pohybu vr\u00e1tane CMR sa uv\u00e1dzali v hertzoch, pri\u010dom ich hodnoty v\u00fdrazne prevy\u0161ovali skuto\u010dn\u00fa obnovovaciu frekvenciu panela. V roku 2015 sa jednotka prestala pou\u017e\u00edva\u0165 a hodnota sa za\u010dala uv\u00e1dza\u0165 ako oby\u010dajn\u00e9 \u010d\u00edslo.<\/p>\n\n\n\n

Na niektor\u00fdch trhoch, najm\u00e4 v USA, Samsung uv\u00e1dzal namiesto PQI hodnotu Motion Rate. Pri nov\u0161\u00edch modeloch sa obe \u010d\u00edsla objavuj\u00fa \u010doraz zriedkavej\u0161ie a technick\u00e9 \u0161pecifik\u00e1cie sa zameriavaj\u00fa na obnovovaciu frekvenciu a konkr\u00e9tne funkcie spracovania pohybu.<\/p>\n\n\n\n

Ako sa vypo\u010d\u00edtava PQI<\/strong><\/h2>\n\n\n\n

Samsung nezverejnil vzorec a recenzenti kritizovali skuto\u010dnos\u0165, \u017ee nikto nem\u00f4\u017ee overi\u0165, ako sa konkr\u00e9tna hodnota vypo\u010d\u00edtava. Pod\u013ea dostupn\u00fdch spr\u00e1v sa pri ur\u010dovan\u00ed hodnoty zoh\u013ead\u0148uje typ panela, rozl\u00ed\u0161enie, jas, kontrastn\u00fd pomer a optimaliz\u00e1cie spracovania obrazu. Ke\u010f\u017ee vstupn\u00e9 \u00fadaje nie s\u00fa zverejnen\u00e9, dva telev\u00edzory s podobn\u00fdm hardv\u00e9rom m\u00f4\u017eu ma\u0165 rozdielne hodnoty.<\/p>\n\n\n\n

Typick\u00fd rozsah sa takmer ka\u017ed\u00fd rok zvy\u0161oval.<\/p>\n\n\n\n

Vy\u0161\u0161ia hodnota odr\u00e1\u017ea bohat\u0161iu v\u00fdbavu, nie nameran\u00e9 zlep\u0161enie kvality obrazu.<\/p>\n\n\n\n

Tabu\u013eka sa kon\u010d\u00ed rokom 2023, preto\u017ee Samsung odvtedy prakticky prestal pou\u017e\u00edva\u0165 PQI. Napr\u00edklad v technick\u00fdch \u0161pecifik\u00e1ci\u00e1ch modelu U8000F z roku 2025 na britskej webovej str\u00e1nke Samsungu sa uv\u00e1dza obnovovacia frekvencia 50 Hz a funkcia Motion Xcelerator, ale hodnota PQI ani Motion Rate sa nespom\u00edna. Niektor\u00ed predajcovia st\u00e1le pon\u00fakaj\u00fa filter PQI, no nov\u0161ie technick\u00e9 \u0161pecifik\u00e1cie sa namiesto toho zameriavaj\u00fa na obnovovaciu frekvenciu a konkr\u00e9tne funkcie.<\/p>\n\n\n\n
