Shamwari dziri kuita cctv dzinogunun'una kuti vatengi vanhasi vakashatiswa nezvishambadzo, vachiti kana mamonitor uye splicing skrini i4K, une 1080P resolution yekutarisa mifananidzo?
Shamwari dzichafinyamisa kumeso dzichiudzana kuti: Hongu, asi inodhura, unoida here?
Zvechokwadi, kubva pakuona kunobatsira, hapana chikonzero che4K mukuchengeteka, uye isu tichiri kuedza kuva hupfumi uye hunobudirira.
Muchokwadi, zvisinei kuti ndiani akabvunza kana kupindura, unomubvunza kuti ataure zvakakomba zvinorevei kuziva 4K? Nzira yekusiyanisa sei pixels uye resolution? 1080P inomirirei? Panogona kunge pasina vazhinji vanogona kupindura.
Pixel: Zvinonyanya kunzwisiswa kuti 1 pixel ndiyo yakakosha unit inogadzira mufananidzo. 2 miriyoni pixels zvinoreva kuti pane 2 miriyoni ekutanga mayuniti pamufananidzo.
Resolution: Tsananguro yakakurumbira ihupamhi × kureba kwechidzitiro, hongu, iyo unit mapixels.
Saka hazvina kuoma kuona kuti pixel ndiyo kukosha kwechigadzirwa chekugadzirisa. 1920×1080=2073600=2 miriyoni pixels; 1600×1200=1920000=mamiriyoni maviri pixels. Uyu muenzaniso unofanirwa kunzwisiswa kana iwe uchigona kuuona zvakajeka.
Nzira yekusiyanisa 720P uye 1080P?
Zviviri izvi ndezvechisarudzo. Iyo P kuseri kwe720P uye 1080P zvinoreva kufambira mberi scan (Chirungu: Progressive). Iyo K mushure me4K inoreva chiuru, zvinoreva kuti yakachinjika resolution inenge 4000 pixels.
Chigadziro hachisi hupamhi × urefu, chirevo chemutsara nemutsetse chinofanira kunge chakakwirira. saka:
720P=1280×720 inowanzonzi HD kana tsanangudzo yepamusoro
1080P=1920×1080 Inowanzonzi FHD kana yakazara HD
4K = 3840 × 2160 inowanzo zivikanwa seQFHD kana Ultra HD
Ndeupi mutsauko mumhando yekuratidzira kana kunaka pakati pazvo?
Kuti tive nyore kunzwisisa, ngatitorei muenzaniso kubva pamifananidzo inogona kuwanikwa zuva rega rega. Wese munhu akaona iyo DVD resolution, iyo inowanzo fanana nekugadziriswa kwesatellite TV, uye kugadzirisa kwetambo TV chikamu chimwe muzvitatu chekugadziriswa kwesatellite TV.
Uye 720P inopeta kana tsananguro yeDVD, 1080P inopeta nechina iyo ye720P, uye 4K yakapetwa kana pane ye1080P.
Naizvozvo, iyo 4K yekupedzisira-yakajeka mufananidzo haienzaniswi muchiyero chekunaka, yakatetepa zvekuti kunyangwe bvudzi rinogona kuoneka zvakajeka!
