Okushiwo isithombe sakho se-TV
Uma uhlala phansi futhi ubukela uhlelo lwakho oluthandayo noma i-movie ku-TV yakho noma iphrojekti yevidiyo, ubona ukuthi kubonakala yini uchungechunge lwezithombe eziphelele, njengezithombe noma ifilimu. Noma kunjalo, ukubonakala kuyakhohlisa. Uma empeleni uthola amehlo akho eduze kwe-TV noma isikrini sokubukwa, uzobona ukuthi sakhiwa amachashazi amancane ahlanganiswe emigqeni enezingqimba futhi eziqondile ngapha nangaphezulu naphansi kwesikrini.
Ukufanisa okuhle iphephandaba elivamile. Uma sikufunda, kubonakala sengathi sibona izithombe nezinhlamvu ezingabodwa, kodwa uma ubheka eduze, noma uthola ingilazi yokukhulisa uzobona ukuthi lezo zithombe nezithombe zakhiwa amachashazi amancane.
I-pixel ichazwe
Amachashazi avela ku-TV, isikrini sokubukwa kwevidiyo, ukuqapha kwe-PC, i-laptop, noma ngisho nezikrini ze-tablet ne-smartphone, kuthiwa yiPixels .
I-pixel ichazwa njengesici sezithombe. I-pixel ngayinye iqukethe ulwazi lombala obomvu, oluhlaza, nolubuluhlaza (okubizwa ngokuthi yi-subpixels). Inani lamaphikseli angaboniswa esikrinini anquma ukuxazulula izithombe ezibonisiwe.
Ukuze ubonise isinqumo esithile sesikrini, inombolo ekhethiwe yamaphikseli kufanele igijime ngaphesheya kwesikrini ngokuzenzekelayo futhi iphinde iphinde iphinde isibuko ngokuqondile, ihlelwe ngemigqa namakholomu.
Ukuze unqume inani lenani lamaphikseli elihlanganisa yonke indawo yeskrini, ukwandisa inani lamaphikseli angemuva emgqeni owodwa nenombolo yamaphikseli aqondile kukholomu eyodwa. Leli nani libizwa ngokuthi yi- Pixel Density .
Izibonelo zobudlelwane bokuxazulula ubukhulu bePielel / Pixel
Nazi ezinye izibonelo zobungqingili be-Pixel yezinqumo eziboniswa ngokuvamile kuma-TVs lanamuhla (i-LCD, i-Plasma, i-OLED) namavidiyo weprojekthi (LCD, DLP):
- I-480i / p imelela ama-pixel angu-740 angama-x 480 angama-pixel angu-345,600.
- I-720p imelela amaphikseli angu-1,280 angama-x 720 angu-pixels angu-921,600.
- I-768p imelela amaphikseli angu-1,366 angama-768 angama-pixel angu-1,049,088.
- I-1080i / 1080p imelela amaphikseli angu-1,920 angama-x 1080 angama-pixels angu-2,073 600.
- I-4K (Umthengi Standard) imelela ama-pixel angu-3,840 ama-pixels angama-2,160 ama-pixel angu-8 294,400.
- I-4K (I-Standard Standard) imelela ama-pixels angu-4,096 angama-2,060 angama-pixels angu-8 847,360.
- I-8K imelela ama-pixels angu-7,680 angama-horizontal angu-4,320 = amaphikseli angu-33 177 600
Ubukhulu bePixel neSayizi Sesikrini
Ngaphezu kokuphakanyiswa kwamaphikseli (isinqumo), kunesinye isici okufanele sicatshangelwe: ubukhulu beskrini esibonisa amaphikseli.
Into eyinhloko okumele ikhombise ukuthi kungakhathaliseki ukuthi usayizi weskrini wangempela, inani le-pixel elilinganiselwe / elilinganiselwe nobunikazi be-pixel alishintshi ngesinqumo esithile. Ngamanye amazwi, uma une-TV ye-1080p, kunamaphikiseli angu-1,920 ahlala njalo ekhrinini ngokuzungezile, umugqa ngamunye, namaphikseli angu-1,080 egijima phezulu nangaphansi kwesibuko ngokuqondile, kukholomu ngayinye. Lokhu kubangela ukulingana kwamaphikseli okungaba yizigidi ezingu-2.1.
Ngamanye amazwi, i-TV engu-32 intshi ekhombisa ukuxazulula kuka-1080p inezinombolo ezifanayo zamaphikseli njengama-55-inch 1080p TV. Into efanayo isebenza kumavidiyo weprojekti. Iprojector yevidiyo ye-1080p izobonisa inombolo efanayo yamaphikseli ku-80 noma 200-intshi yeskrini.
Amaphikseli Nge-intshi
Noma kunjalo, noma ngabe inani lamaphikseli lihlala liqhubeka njalo ngokulingana kwamaphikseli athile kuwo wonke ubukhulu beskrini, ukuguqulwa kuyinani lamaphikseli-ngamasentimitha . Ngamanye amazwi, njengoba usayizi weskrini ukhula, ama-pixel aboniswa ngabanye kumele abe mkhulu ukuze agcwalise isikrini ngenani elifanele lamaphikseli ngesinqumo esithile. Ungakwazi ngempela ukubala inani lamaphikseli ngamasentimitha ngamasentimitha athile wokuxazulula / usayizi weskrini.
Amaphikseli Ngama-inch - Amaprosesa we-TV vs Isiqophi
Kubalulekile ukuthi uqaphele ukuthi ngamavidiyo wesipredishithi, amaphikseli abonisiwe nge-intshi yeprojekti ethile angashintsha kuye ngokuthi isayizi lesayizi esetshenzisiwe. Ngamanye amazwi, ngokungafani nama-TV anama-screen esayizi-static (ngamanye amazwi, njengoba i-TV engu-50 intshi njalo i-TV-intshi engu-50 intshi), amavidyo wevidiyo angabonisa izithombe ezinhlobonhlobo zobukhulu beskrini, kuye ngokuklanywa kwendlalelo yeprojekthi ibanga umshini weprojekti usekwe kwesikrini noma odongeni.
Ngaphezu kwalokho, ngama-projectors we-4K, kunezindlela ezahlukene ukuthi izithombe zikhonjiswa kanjani esikrinini esiphinde sithinte usayizi weskrini, ubukhulu bamaphikseli, namaphikseli ngobuhlobo bomthamo.
Okubalulekile
Nakuba ama-Pixels ayisisekelo sokuthi isithombe se-TV sihlanganiswa kanjani, kunezinye izinto ezidingekayo ukubona izithombe ezinhle ze-TV noma izithombe zeprojekthi, ezifana nombala, umehluko, nokukhanya. Ngenxa yokuthi unamaphikseli amaningi, akusho ukuthi uzothola isithombe esihle kunazo zonke ku-TV yakho noma iphrojekthi yevidiyo.
