Ulawulo lombala kwiimonitha ze-OLED: lungelelanisa ukunqanda "ukutyumza okumnyama"

Ngamanye amaxesha, ebomini bakho Isikrini se-OLED okanye iliso Imiboniso emnyama ibonakala ngathi isileyiti esingenanto. Lonto inegama: yeyona idumileyo tyumza emnyamaLo mcimbi ubangela ukuba ukuthungwa kulahleke kwithunzi kunye nezinto ezikhanyiswe luzizi ukuba zinyamalale.

Ngokwesiqhelo, uluhlu lwetoni kufutshane nomnyama lucinezelekile kwaye alusabonisi ama-nuances akhoyo kumqondiso. Ngethamsanqa, Kukho iindlela zokuphepha ukutyumza okumnyama, okanye ukuxilonga ngeemvavanyo ezilula kunye nokunciphisa kwiimodeli ezininzi ngokulungelelanisa umfanekiso okanye, ukuba kuyimfuneko, ukulinganisa.

Yintoni ukutyumza okumnyama kwaye kutheni kwenzeka kwi-OLED?

Ukutyumza okumnyama yingxaki eqhelekileyo kwaye iyacaphukisa njenge... ukutshisa ngaphakathiKule meko, malunga nokulahlekelwa kweenkcukacha kwiithoni ezimnyama. Akunjalo ukuba umnyama uyayeka ukuba mnyama, kodwa kunokuba kunjalo Amanqanaba asondele kumnyama adityaniswe kunye kwaye bayayeka ukwahluka.

Oku kunokwenziwa ngabom: abanye abavelisi bakhetha ukufihla izinto zakudala zesiqulatho esicinezelekileyo, njengebhanti, i-posterization, okanye ingxolo, kwaye ukwenza njalo, baqinisa ijika ekupheleni kwezantsi. Kukwakho nabahloli abahlengahlengisa ijika labo ngale ndlela yokunciphisa i-chromatic overshoot, oko kukuthi, ukudubula kombala omncinci ojikeleze iinguqu ezimnyama kakhulu.

Ukuziqhelanisa, uya kubona ukuba imiboniso yasebusuku okanye izinto zangaphakathi ezikhanyayo zilahlekelwa ziinkcukacha ezincinci: ukugoba kwiihempe ezimnyama, ukuthungwa kwi-asphalt Okanye iikona zamagumbi ziba luzizi. Oku kwenzeka kakhulu ezivenkileni kuba iindlela zokubonisa azisoloko zichaneka kakhulu, kwaye ukukhanya kwe-ambient kuyayibaxa imbono yomahluko. Yiyo loo nto, xa uthelekisa i-OLED kunye ne-LED ecaleni kwayo, i-LED ibonakala ibonisa izithunzi ezininzi xa i-OLED ingabonisi ngokuchanekileyo.

Uvavanywa njani ukuba isikrini sakho sinokutyumza okumnyama

Eyona ndlela ichanekileyo yokufumanisa nokuphepha ukutyumza okumnyama sebenzisa ipateni yeepetshi zezithunzi ezikufutshane kakhulu kumnyama. Yigridi enezikwere ukusuka kumnyama ngokupheleleyo ukuya kumanqanaba amaninzi ngaphezulu. Kolu vavanyo, ukubonakala kwezikwere zokuqala Ikuxelela ukuba ummandla okufuphi nomnyama uphendula njani. Kukho i-nuance ebalulekileyo nge-gamma: kwi-Windows, isethingi engagqibekanga idla ngokuba yi-sRGB gamma; kulo meko, isikwere ngasinye siya kubonakala ngokulula.

Ukuba unyanzelisa okanye uqwalasele i-gamma ye-flat ye-2.2, esemgangathweni we-SDR kwiindawo ezininzi, into echanekileyo ukuyenza. iipatches ezimbini okanye ezintathu zokuqala azibonakali emnyama kumgama oqhelekileyo wokujonga. Ukuba kwimeko yakho iipatches ezintlanu okanye ezisibhozo zokuqala azibonakali ngokupheleleyo, unomlinganiselo omnyama wokutyumza. Ukuba amabala amaninzi ayanyamalala, ukutyumza kubukhali ngokucacileyo. Kwiimonitha ezahlukeneyo kunye nomabonakude, oku kunokwahluka kunye nolawulo lokukhanya ngokubanzi, ke qaphela imodeli kwaye ujonge ukuba inani lamabala abonakalayo liyatshintsha xa unyusa okanye uthoba inqanaba lokuqaqamba.

Gcina ukhumbula ukuba amanye amaqonga okanye iinethiwekhi zinokucinezela okanye ziguqule imifanekiso yovavanyo. Ukuba ukrokrela ukuba umfanekiso wovavanyo uguqulwe ngokucinezelwa, zama ukujonga ipateni evela kumthombo wokuqala okanye layisha ifayile ekuhlaleni ukuze indawo yolawulo iyitolike kanye njengoko ibhaliwe.

I-OLED vs. I-LED kwivenkile: xa abamnyama bamnyama kakhulu

Ecaleni kwe-LED, i rajanud Kubonakala kushiya yonke into ebumnyameni obupheleleyo. Umzekelo: kwindawo enamanzi okanye izithunzi ekoneni, I-LED ivumela iingcebiso zokubonisa kunye nokuthungwangelixa i-OLED ingabonisi nto. Kwenzeka into efanayo ngehempe emnyama: kwi I-LED Imibimbi ibonakala kwiscreen, kodwa iyaphela kwisiboniso se-OLED.

Oku akuthethi ukuba i-OLED imbi. Idla ngokuba luseto kunye nemeko-bume esebenza ngokuchasene nayo. Ukukhanya kwe-Fluorescent ukusuka phezulu, iindlela zemifanekiso yedemo, kunye nokungabikho kwexesha lohlengahlengiso kunokwenza i-OLED ibonakale imnyama emthunzini. Ngeprofayile yomfanekiso efanelekileyo kunye ulungelelwaniso oluchanekileyo lwe-gamma okanye ukusuka kwi-EOTF, i-OLED kufuneka iphinde ifumane ezo nuances ngaphandle kokuphulukana ne-advanteji yayo: abamnyama bokwenyani kunye nepikseli yokuchasana okungapheliyo ngepikseli.

I-Gamma, i-sRGB kunye novavanyo lwe-patch: tolika oko ukubona ngokuchanekileyo

Inqaku elibalulekileyo malunga novavanyo lwepetshi: Kwiimeko-bume zedesktop yeWindows, iqhelekile kulawulo lwesixokelelwano ukukukhokelela kwindawo yombala we-sRGB.Phantsi kolu kuziphatha, iipetshi ezikufutshane nomnyama zivula ngakumbi, kwaye unokukwazi ukubona zonke izikwere zepateni. Oku akuthethi ukuba indawo yolawulo yakho igqibelele; kuthetha nje ukuba ijiko le-sRGB longeza ukuthomalalisa kancinci emthunzini okwandisa ukubonakala kweenkcukacha ezincinci.

Xa usebenzisa i-gamma ethe tyaba ye-2.2, eyireferensi eqhelekileyo kwi-SDR, kufuneka ulindele ukuba izakhelo ezimbini okanye ezintathu zokuqala zepateni zingabonakali kumgama oqhelekileyo wokujonga. Ukuba, phantsi kwezo meko, awukwazi ukubona iifreyimu zokuqala ezintlanu okanye ezisibhozo, luphawu olucacileyo lokutyumza okuphakathi kwabantu abamnyama. Qaphela kwakhona ukuba njani utshintsho lokukhanya kwehlabathi Batshintsha isiphumo, kuba ngokwe-elektroniki yephaneli, ukwandisa ukukhanya kunokuvula ngakumbi okanye ukuvala indawo esezantsi.

Kwaye ukuba awuqinisekanga ukuba ipateni oyisebenzisayo ifanelekile na, kunqande ukuyivelisa kwakhona kwindawo apho inokucinezelwa okanye iguqulwe. Ngokufanelekileyo, sebenzisa ifayile yendawo okanye umthombo othembekileyo ukuze Musa ukukhohliswa yikhowudiNabani na onomdla malunga nabamnyama kwi-HDR unokwenza uthelekiso oluhambelanayo: i-PQ iyinyani kwaye nakuphi na ukutenxa kwii-nits zokuqala kubonakala ngokukhawuleza.

Xa i-HDR ibonakala imnyama: imeko eqhelekileyo kwiimonitha

Abanye abasebenzisi be-OLED ebeke iliso baye baxela ukuba kwiimowudi ezinjenge-HDR1000, yonke into ibonakala imnyama kakhulu, kangangokuba nabani na ongena kwigumbi uya kuqaphela. Oku kulungelelaniswa nesiphumo esimnyama sokutyumza kuqiniswa yimephu yethowuni yemonitha kunye nendlela... I-EOTF PQ iyaqhubeka nokulandela isalathiso kwindawo esezantsi, kwaye kwiimeko ezininzi I-HDR yemonitha yakho inokuba mandundu ngaphezu kwe-SDR. Ukuba, ukongeza, imowudi ye-HDR yemonitha inobundlongondlongo kunye negophe, kuyinto eqhelekileyo ukuba iindawo zomthunzi zitshone kakhulu.

Kwezi meko, kuyacetyiswa ukuba uphonononge imowudi ye-HDR ekhethiweyo kunye nokuphatha isithunzi. Ayizizo zonke iiphaneli ezibonelela ngokucokisekileyo kwi-HDR ngohlengahlengiso lwendawo, kodwa naluphi na ulawulo kumanqanaba amnyama okanye kufutshane ne-shading emnyama inceda ukuthomalalisa imeko. Xa ibhalansi emhlophe yebala ifumaneka kwi-HDR, izikhokelo ze phakamisa kancinci amanyathelo okuqala Ngoonomoyi badla ngokunika umoya ngaphandle kokudala isigqubuthelo kwabamnyama.

Ii-Macroblocks, iibhendi kunye nemigca: ayisiyiyo yonke into emnyama kukutyumza okumnyama

Ayizizo zonke ii-anomalies kwimiboniso emnyama efanayo. Umsebenzisi omnye one-LG OLED B8 uchaze imiboniso yasebusuku enamabhanti aqaqambileyo athe nkqo kwicala lasekhohlo ngamaxesha athile, ukongeza kwimigca emibini ethe tye ehlala ibonakala kwindawo enye. Le pateni emiselweyo yeebhendi okanye imigca icebisa ukufana okanye iingxaki zokucubungula, ezithi Abaziphathi njengee-macroblocks eziqhelekileyo yoxinzelelo lwevidiyo.

Ii-Macroblocks ziibhloko ezinkulu eziqhwayiza okanye ezikhanya ngokungaqhelekanga kwiindawo ezixineneyo, ngakumbi nge-bitrate ephantsi kunye nakwizithunzi ezinzima. Oko kwakuchazwa, kwelinye icala, yayiziindawo ezikhaphukhaphu ezingazange ziqhwayize kunye nemigca ezinzileyo, into ekufutshane nebhendi okanye isignesha yepaneli. Kwiindibano zocweyo, ukuba indawo emnyama ayiveliswanga ngokuchanekileyo kwaye igumbi alikho mnyama, Kulula ukuba igcisa liyiphose.Yiyo loo nto kubalulekile ukuqaphela umzuzu ochanekileyo kunye nomxholo kwaye uhlengahlengise ngononophelo umabonwakude ngaphambi kokuba wenze izigqibo.

Ukuba udibana nento enje, qalisa ngokuqwalasela ngokucokisekileyo umfanekiso, ukhethe imowudi ethembekileyo, kwaye ujonge naluphi na uphuculo lomphetho okanye ukugudisa okungazisa iziphumo ebezingalindelekanga ezingafunekiyo. Uthelekiso lwesakhelo ngesakhelo kunye nomnye umthombo lunokunceda ukufumanisa ukuba umba ukwifayile okanye kwindawo yolawulo. Ngamaxesha athile, ngokuseta kakuhle Imbono yeebhendi iyancipha kakhulu kumxholo wangempela.

I-OLED emnyama kakhulu kwi-cinema kodwa inokwakheka: indlela yokulinganisa okulindelweyo

Ukuba i-OLED ihambisa abamnyama abamsulwa bubuhle. Injongo ayikokunyusa umnyama ukuze ubone ngwevu, kodwa kukugcina umnyama osulungekileyo ngelixa ubuyisela izithunzi ezimbalwa zokuqala zesithunzi. Ke ngoko, xa uhlengahlengisa useto, qiniseka ukuba iimvavanyo zokuqaqamba kweepesenti ezi-0 zihlala zimnyama kubumnyama obupheleleyo kwaye oko amabala amancinci okanye iinkcukacha ezikufutshane vela kwakhona. Inqaku elichanekileyo kukutyhila ukuthungwa ngaphandle kokuguqula umfanekiso ube yindawo yokuhlamba.

Xa kuthelekiswa ne-LED, kubalulekile ukuqonda ukuba ukukhanya kwe-haloing kunye nokunyuswa okumnyama kunokunika inkcazo yeenkcukacha ezithe kratya kwizithunzi xa enyanisweni isisigqubuthelo esincinci. Nge-OLED elungiswe kakuhle, iinkcukacha ezintle kufuneka zibe khona. Ukuba ukhetha phakathi kweemodeli ezifana ne-A80K kunye nenye indlela ye-LED efana ne-X90K, khumbula ukuba iprofayile yefilimu echanekileyo kunye ne-gamma I-OLED inokubonisa ihempe okanye ekhazimlayo kwi-puddle ngaphandle kokuncama ubumnyama bayo ngokupheleleyo.

Izilumkiso malunga nokugcinwa kunye nokutshisa ngaphakathi kwi-OLED

Ii-OLED zinovelwano kwimifanekiso emileyo eboniswa ixesha elide. Iilogo zenethiwekhi, iigrafiki zeendaba, iibhodi zomdlalo wevidiyo, okanye iibar zojongano zinokushiya amanqaku. Ke ngoko, ukongeza ukulungelelanisa ngokufanelekileyo umfanekiso kunye nokusombulula ukutyumza okumnyama, Izikhundla ezimile ixesha elide kufuneka ziphetshwe kwaye uvumele imijikelo yolondolozo lwephaneli yenze umsebenzi wabo xa iTV iyibonisa.

Ukuba ubona izithunzi okanye ukugcinwa kwemifanekiso, landela izikhokelo zomenzi ukuze uzinciphise. Ukugcina imikhwa yokusetyenziswa efanelekileyo kunye nokuphepha ukujonga ngokugqithiseleyo umxholo kunye nezinto ezimileyo ekukhanyeni okuphezulu kunceda ukugcina ipaneli ikwimeko entle. Amaxesha amaninzi, oku kuphela okufunekayo. yahlula umxholo okanye uvule iindlela zesiqhelo Izinga lokuhlaziya i-pixel ukuze ezo minwe ziphele ngokuhamba kwexesha.

Iingcebiso ezikhawulezayo zokunciphisa okanye ukuphepha ukutyumza okumnyama ngaphandle kokwenza izinto ezinzima

Kwabo bafuna ukuphuculwa ngokukhawuleza ngaphandle kokungena kwi-point-by-point adjustment, iingcebiso ezimbalwa ezilula zingenza umehluko. Khetha iindlela zemifanekiso ezifana neCinema okanye uMenzi wefilimu, khubaza ukusetyenzwa ndlongo, kwaye uhlengahlengise inqanaba elimnyama okanye ukukhanya ukuze ipateni ibonise ubuncinci. isiqwenga sesithathu okanye sesine Xa usebenzisa i-gamma 2.2, zama ukugcina ukukhanya kwegumbi kulawulwa ukuze imbono yesithunzi ihambelane.

Kwi-LG C1, B1, kunye ne-G1, ukuba ulungele ukusebenzisa ibhalansi emhlophe yamanqaku angama-22, sebenzisa ukunyuka okucetyiswayo kumanqanaba aphantsi, kwi-SDR kunye ne-HDR. Uya kubona ukuba ukwakheka okufihliweyo kuphinda kuvele njani ngaphandle kokonakalisa umahluko. Kwaye khumbula: ukuba ufuna ukuchaneka ngokupheleleyo, iprobe calibration Ilungelelanisa isikrini kunye nesalathiso kwaye iqinisekisa umkhondo ococekileyo kwabamnyama.

Isishwankathelo: ukuphepha ukutyumza okumnyama kulula kakhulu ukuba siyayivavanya ngokuchasene nomgangatho othembekileyo kwaye siyawuqonda umahluko phakathi kwe-sRGB gamma kunye ne-flat 2.2 aperture. Ngolungelelwaniso olulinganiswe kakuhle kwindawo ekufutshane-emnyama, nokuguqula ibhalansi emhlophe ngamanqaku omntu ngamnye kwiimodeli ezifana ne-LG C1, B1, kunye ne-G1, kunokwenzeka ukubuyisela iinkcukacha zesithunzi ngaphandle kokunyusa amanqanaba amnyama. Ukuba ukwahlula phakathi kwezinto ezenziweyo zoxinzelelo, ibhendi, okanye imigca engatshintshiyo, kwaye ulumkele ukusetyenziswa kwakho ukunqanda ukugcinwa komfanekiso, Isikrini sakho se-OLED siya kubuyisa amava e-cinema njengoko kufanele ukubonwa.ngobumnyama obunzulu kunye nokuthungwa okuhle apho kubalulekile.

Inqaku elidibeneyo:

I-HDR yemonitha yakho inokuba mbi ngakumbi kune-SDR: Ungayicima nini kwaye uyilinganise kakuhle njani
