Abahlobo ababandakanyekayo kwi-cctv bakhalaza ukuba abathengi banamhlanje bonakaliswe zizibhengezo, besithi ingaba iimonitha kunye nezikrini ze-splicing ziyi-4K, unayo i-1080P isisombululo semifanekiso yokubeka iliso?
Abahlobo baya kufinga iintshiya baze bathi omnye komnye: Ewe, kodwa kuyabiza, uyafuna?
Ngokuqinisekileyo, ukusuka kumbono osebenzayo, akukho mfuneko ye-4K ekukhuseleni, kwaye kusafuneka sizame ukuba ngowona qoqosho kunye nokusebenzayo.
Enyanisweni, kungakhathaliseki ukuba ngubani obuza okanye uphendule, ngaba uyamcela ukuba athethe ngokunyanisekileyo ukuba kuthetha ukuthini ukwazi i-4K? Ukwahlula njani phakathi kweepixels kunye nesisombululo? Imele ntoni i-1080P? Mhlawumbi ababaninzi abanokuphendula.
I-Pixel: Kuyaqondwa ukuba i-pixel enye yeyona yunithi isisiseko eyenza umfanekiso. Izigidi ezi-2 zeepikseli zithetha ukuba kukho izigidi ezi-2 zeeyunithi ezisisiseko emfanekisweni.
Isisombululo: Ingcaciso edumileyo bububanzi × ubude besikrini, ewe, iyunithi ziipixels.
Ke akunzima ukubona ukuba ipixel lixabiso lemveliso yesisombululo. 1920×1080=2073600=2 million pixels; 1600×1200=1920000=2 million pixels. Lo mzekelo kufuneka uqondwe ukuba unokuwubona ngokucacileyo.
Ukwahlula njani i-720P kunye ne-1080P?
Ezi zimbini zezesisombululo. I-P emva kwe-720P kunye ne-1080P ithetha i-progressive scan (isiNgesi: i-Progressive). I-K emva kwe-4K ithetha iwaka, okuthetha ukuba isisombululo esithe tye malunga ne-4000 pixels.
Isisombululo asikho ububanzi × ubude, intsingiselo yomgca ngomgca kufuneka ibe phezulu. ngoko:
720P=1280×720 idla ngokubizwa ngokuba yiHD okanye inkcazo ephezulu
1080P=1920×1080 Idla ngokuba yiFHD okanye iHD epheleleyo
4K = 3840×2160 eyaziwa ngokuba QFHD okanye Ultra HD
Yintoni umahluko kumgangatho wokubonisa okanye umgangatho phakathi kwabo?
Ukuze kube lula ukuqonda, makhe sithathe umzekelo kwimifanekiso enokufikelelwa yonke imihla. Wonke umntu uye wabona isisombululo seDVD, esifana ngokuqhelekileyo nesisombululo seTV yesathelayithi, kunye nesisombululo seTV yentambo sisinye kwisithathu sesisombululo seTV yesathelayithi.
Kwaye i-720P iphindwe kane inkcazo yeDVD, i-1080P iphindwe kane kune-720P, kwaye i-4K iphindwe kane kune-1080P.
Ke ngoko, umfanekiso ocacileyo we-4K awunakulinganiswa kwinqanaba lobumnandi, uthambile kangangokuba neenwele zibonakala ngokucacileyo!
