Isilinganiso sokuhlukanisa i-TV kungenzeka ukuthi isici esikhulu esiyiphutha esingasisebenzisa uma uqhathanisa i-HDTV ngoba nakuba isilinganiso sokuqhathanisa singabikwa njengokufana phakathi kwamamodeli, umehluko wangempela ungahluka. Lokhu kungavumelani nalokho okungekho izinga lemikhakha yokulinganisa.
Noma kunjalo, naphezu kokukhala kwamanye amakhono embonini, isilinganiso sokuqhathanisa siyisici esibalulekile sokuqonda ngoba sibhekene nokukhanya, yiziphi izikhamera eziphuma.
Njengoba ufunda ngalesi sihloko uzothola ukuqonda ukuthi yini nokuthi nini ukuyisebenzisa ukwenza isinqumo esingcono sokuthenga.
Iyini isilinganiso sokungafani kwe-TV?
Ake sithi sisesitolo esibheke ukubukwa kwe- HDTV . Manje, asho ukuthi kukhona into esesikrinini esinomxube wezithombe ezikhanyayo nezomnyama, njengokubuka ngaphandle emgodini omnyama ube ngelanga.
Njengoba sibheka izikrini kufanele sibheke umehluko ngemininingwane phakathi kwephaneli ngayinye. Iphaneli eyodwa ingahle ibonise ukuthi izakhi emdongeni wamaphandolo ngenye imininingwane ngenkathi enye i-HDTV ingabonisa udonga olufanayo njengento engaphezu kombala oqinile ngaphandle kwemininingwane eminingi noma ukuthungwa.
Lena isilinganiso sokuhlukanisa i-TV ngokuphazima kweso - inani lemininingwane yesikrini kubomnyama neminye imibala emnyama.
Ngokwengqondo, isilinganiso sokuhlukanisa i-TV senza umehluko wokukhanya phakathi komnyama okhanyayo omhlophe futhi omnyama kunabo bonke abangakhiqizwa esikrinini ngokubukwa kokubukwa, kodwa yilezi zithombe ezimnyama ezibonisa kubonakala zinenkinga enkulu yokukhiqiza.
Kuyini Ukulinganiswa Kokubukwa kwe-TV Kubukeka?
Njengomthengi, uzobona isilinganiso sokuphambene esibalulwe emaphaketheni yomkhiqizo nokucaciswa.
Isibonelo singaba isilinganiso esiphathelene nesibalo se-2,500: 1, okusho ukuthi umhlophe ogqamile kakhulu izikhathi ezingu-2 500 kunomnyama omnyama kakhulu. Ukucatshangelwa okujwayelekile ukuthi ukukhula okukhulu kunamazinga amaningi emininingwane aboniswa kusikrini.
I-curveball yukuthi kunezilinganiso ezimbili zokulinganisa kwe-TV, ngakho-ke amaqoqo amabili e-ratios. Lezi zilinganiso zibizwa ngokuthi zi-static futhi zishintsha. Zihluke kakhulu, ngakho-ke kubalulekile ukwazi ukuthi ubhekephi.
Ukusebenzisa isibonelo sethu ngenhla, i-TV ene-2,500: isilinganiso esingu-1 static contrast singaba nesilinganiso sokuqhathanisa esinamandla esingu-25,000: 1. Ngakho-ke, kungcono? Awukho ngempela. Izindlela ezihlukile ukuze zikhiqize imiphumela ehlukene. Ukuqhathanisa ukusimama ngokumelene noshukumisayo kungafana nokuqhathanisa ama-apula nama-oranges.
Kuyini Ukulinganiswa Okuyisimanga Nokuqeda Amandla?
Ukulinganiswa kwe-TV kubikwa kubathengi njengokuthi kuyisimo esiqinile noma esinamandla. I-Static ibizwa nangokuthi iyisizwe noma isikrini. Noma kunjalo, yilapho isilinganiso sokuqhathanisa sibonakala sinkimbinkimbi futhi ngempela umthengi akudingeki wazi imininingwane yokuthi izilinganiso ezilinganisako neziqine kangakanani zihluke komunye nomunye.
Yimaphi abathengi abadinga ngempela ukwazi ukuthi yiliphi izinga lokuhlukanisa elibikwayo - eliyi-static noma elinamandla. Abaningi embonini yezimboni bakholelwa ukuthi izibalo ziyizinombolo ezinembile kakhulu noma ezinokwethenjelwa kusukela inqubo yokulinganisa ithola imiphumela engaphezulu "yezwe langempela" kunokulinganisa okunamandla.
Ukuphikisana kokulinganisa kwe-TV
Ukulinganisa kwe-TV kungenye yezincazelo eziphambene kakhulu uma kuqhathaniswa amathelevishini avela kumkhiqizi kumkhiqizi ngoba imboni ayinayo izinga elilinganiselwe lokulinganisa.
Ngaphandle kwezinga elijwayelekile, asazi kahle ukuthi umkhiqizi ngamunye uhlola kanjani ukubonisa kwawo nendlela inqubo yabo ehluke ngayo kwabanye abakhiqizi. Ngenxa yalokho, izimboni zezolimo zincoma ukusebenzisa ukulinganisa isilinganiso kuphela lapho kuqhathaniswa i-HDTV eyenziwe ngumenzi ofanayo.
Ukucatshangelwa okuvamile phakathi kwababoni bemboni ukuthi isilinganiso sokuhlukanisa okuyi-static yisilinganiso esinokwethenjelwa ngokwengeziwe ngoba sihambisana kakhulu nendlela ukubukwa kokubukwa kuzobonisa okuqukethwe kunokuthi "kwenzekani uma" isimo esiqhathaniswa nesilinganiso sokuqhathanisa sisebenza.
Ukulinganisa kwe-TV Ukulinganisa Ukuthenga Iseluleko
Sebenzisa lokhu okulandelayo njengomhlahlandlela jikelele ukuqhathanisa ukulinganisa okuphakathi kwe-HDTVs:
- Sebenzisa isilinganiso sokuqhathanisa kuphela uma uqhathanisa i-HDTV eyenziwe ngumenzi ofanayo. Isibonelo, i-Sony kuya ku-Sony, hhayi i-Sony kuya ku-Samsung.
- Qhathanisa noma i-static ibe yi-static noma iguquguquke ukuze iguqule kodwa ungaqhathanisi ne-Static kuya enamandla.
- Khumbula ukuthi isilinganiso sokuhlukanisa siyisisodwa sezici eziningi okufanele uzicabangele uma uthenga i-HDTV . Kithina, ukulinganisa isilinganiso kungaba phansi ohlwini lwabahluleli ngoba izilinganiso azihambisani nomkhiqizi kumkhiqizi. Kunalokho, sebenzisa amehlo akho ukuthola ukuthi umehluko uhlangabezana nezidingo zakho ezibukwayo.
