Abangane abenza i-cctv bakhala ngokuthi amakhasimende anamuhla amoshwa yizikhangiso, bethi noma ama-monitor nama-splicing screens yi-4K, ingabe unayo i-1080P resolution yezithombe zokuqapha?
Abangane bazohwaqana bese betshelana: Yebo, kodwa kuyabiza, uyakufuna?
Yiqiniso, ngokombono osebenzayo, asikho isidingo se-4K ekuvikelekeni, futhi sisafanele sizame ukonga kakhulu futhi ngempumelelo.
Eqinisweni, kungakhathaliseki ukuthi ubani obuze noma ophendule, uyambuza ukuthi asho ukuthi kusho ukuthini ukwazi i-4K? Ungahlukanisa kanjani phakathi kwamaphikseli nesinqumo? Imele ini i-1080P? Cishe ababaningi abangaphendula.
I-Pixel: Kuyaqondakala ukuthi iphikseli elingu-1 iyunithi eyisisekelo eyenza isithombe. Amaphikseli ayizigidi ezi-2 kusho ukuthi kunamayunithi ayisisekelo ayizigidi ezi-2 esithombeni.
Isixazululo: Incazelo edumile ububanzi × ubude besikrini, vele, iyunithi ingamaphikseli.
Ngakho-ke akunzima ukubona ukuthi i-pixel iyinani lomkhiqizo wesinqumo. 1920×1080=2073600=2 million pixels; 1600×1200=1920000=2 million pixels. Lesi sibonelo kufanele siqondwe uma ungasibona ngokucacile.
Ungahlukanisa kanjani i-720P ne-1080P?
Zombili lezi ziyingxenye yesinqumo. I-P ngemuva kwe-720P ne-1080P isho ukuskena okuqhubekayo (IsiNgisi: Okuqhubekayo). I-K emva kwe-4K isho inkulungwane, okusho ukuthi ukulungiswa okuvundlile kungamaphikseli angu-4000.
Isixazululo akubona ububanzi × ubude, incazelo yomugqa ngomugqa kufanele ibe phezulu. ngakho:
720P=1280×720 ngokuvamile ebizwa nge-HD noma ukucaca okuphezulu
1080P=1920×1080 Ivamise ukubizwa nge-FHD noma i-HD egcwele
4K=3840×2160 ngokuvamile eyaziwa ngokuthi QFHD noma Ultra HD
Uyini umehluko kwikhwalithi yokubonisa noma ikhwalithi phakathi kwabo?
Ukuze kube lula ukuqonda, ake sithathe isibonelo ezithombeni ezingafinyeleleka nsuku zonke. Wonke umuntu uye wabona ukulungiswa kwe-DVD, okuvame ukufana nokuxazululwa kwe-TV yesathelayithi, futhi ukulungiswa kwe-cable TV kuyingxenye eyodwa kwezintathu yesinqumo se-TV yesathelayithi.
Futhi i-720P iphindwe kane incazelo ye-DVD, i-1080P iphindwe kane kune-720P, futhi i-4K iphindwe kane kune-1080P.
Ngakho-ke, isithombe esicacile se-4K asinakuqhathaniswa ngezinga lokudakwa, sintekenteke kangangokuthi ngisho nezinwele zingabonakala ngokucacile!
