Zomwe 1080p zili ndi chifukwa chake ziri zofunika pa dziko la TV
Pogula masewera atsopano a TV kapena kunyumba, ogula amawombedwa ndi mawu omwe angakhale osokoneza.
Chinthu chimodzi chosokoneza ndi kusintha kwa kanema . 1080p ndi yankho lofunika la kanema loti mumvetse koma limatanthauza chiyani?
Tanthauzo la 1080p
1080p imayimira mapikseli 1,920 omwe amawonetsedwa pawindo pang'onopang'ono ndi ma pixel 1,080 pansi pazenera.
Ma pixel akukonzedwa mzere kapena mizere. Izi zikutanthauza kuti mapilosi a 1,920 akuyikidwa m'mizere yozungulira yomwe imadutsa chophimba kuchokera kumanzere kupita kumanja (kapena kumanja kupita kumanzere ngati mukufuna), pamene ma pixel 1,080 akonzedwa mumzere kapena mizere, yomwe imachokera pamwamba mpaka pansi pazenera . 1,080 (yomwe imatchedwa chisankho chosakanikirana - kuyambira kumapeto kwa mzere umodzi wa pixel uli kumanzere ndi kumanja komweko kwa chinsalu) ndi pamene gawo la 1080 la 1080p likuchokera.
Total Number Of Pixels Mu 1080p
Mungaganize kuti mapilosi 1,920 omwe akuwonetsedwa pawindo, ndipo ma pixel 1,080 akuthamanga kuchokera pamwamba mpaka pansi, samawoneka ngati ochuluka. Komabe, mukachulukitsa chiwerengero cha pixel (1920) ndi pansi (1080), chiwerengero chawo ndi 2,073,600. Ichi ndi chiwerengero cha mapikseli omwe akuwonetsedwa pawindo. Mujambula kamera / kujambula zithunzi, izi ndi pafupi 2 Megapixels. Izi zimatchulidwa ngati Kulemera kwa Pixel.
Komabe, ngakhale chiwerengero cha ma pixelisi chikhale chomwecho mosasamala kanthu za kukula kwawindo, chiwerengero cha pixel-inch chimasintha monga kukula kwazithunzi .
Kumene 1080p Kumalowa
1080p imatengedwa kukhala pamwamba pa kanema kamangidwe kamene kamagwiritsidwa ntchito pa ma TV ndi mavidiyo (pakali pano 4K ndi apamwamba kwambiri - ofanana ndi 8.3 megapixels ), ilibe kandulo kumasikapixel ndondomeko ya ngakhale digitala yotsika mtengo komabe makamera. Chifukwa cha ichi ndikuti pamafunika kuchuluka kwamtunduwu ndi mphamvu yogwiritsira ntchito kupanga mafano osuntha kusiyana ndi mafano, ndipo pakalipano, kuthetsa kanema pa kanema komwe kuli kotheka pogwiritsira ntchito zamakono zamakono ndi 8K, ndipo pamapeto pake ikuyandikira ma digapixel 332 ). Komabe, tidzakhalanso ndi zaka zingapo tisanathe kuona ma TV 8K monga mankhwala omwe amaperekedwa kwa ogula.
Apa akubwera The & # 34; P & # 34; Gawo
Chabwino, tsopano kuti muli ndi gawo la pixel la 1080p pansi, nanga bwanji P? Chimene P imayimira ndicho kupita patsogolo. Ayi, izo ziribe kanthu kochita ndi ndale koma zimakhudzana ndi momwe pixel imayendera (kapena mizere) ikuwonetsedwa pa TV kapena kanema kuyang'ana chithunzi. Pamene fano likuwonekera pang'onopang'ono, zikutanthauza kuti mizere ya pixel yonse imasonyezedwa pazenera sequentially (imodzi pambuyo pa chiwerengero).
Zomwe 1080p Zimakhudzana ndi Ma TV
1080p ndi mbali ya High-Definition video standards malo. Mwachitsanzo, ma HDTV, makamaka omwe ali ndi masentimita 40 kapena akuluakulu , ali ndi chiwonetsero cha 1080p chowonetsera (kapena pixel) (ngakhale chiwerengero chikuwonjezeka tsopano ndi 4K Ultra HD TV).
Izi zikutanthauza kuti ngati mulowetsa mu TV ya 1080p yomwe ili ndi chigamulo chochepera 1080p, TV ikuyenera kuyitanitsa chizindikirocho kuti iwonetse chithunzicho pazenera lonse. Njira imeneyi imatchedwa Upscaling .
Izi zikutanthawuzanso kuti zizindikiro zolembera ndi zosachepera 1080p zosankha sizidzawoneka bwino ngati chizindikiro choona cha vidiyo ya 1080p chifukwa TV ikukwaniritsa zimene zikusowa. Ndi mafano osunthira, izi zingayambitse zinthu zosafunika zomwe zimakhala ngati m'mphepete mwa mzere, mtundu wa magazi, kuphulika kwa magazi , ndi kuponyedwa kwapadera (izi ndizochitika posewera matepi a VHS akale!). Pamene mukuganiza kuti TV ikupanga, chithunzichi chidzawoneka bwino. TV siyenera kukhala ndi vuto lililonse ndi zizindikiro 1080p zopangira, mongazo kuchokera ku Blu-ray Disc, ndi maulendo othamanga / chingwe / satana omwe angapereke chithandizo mu 1080p.
Zizindikiro zosindikizira pa TV ndi zina. Ngakhale kuti 1080p amaonedwa kuti ndi Full HD, sizimayendetsedwa bwino ndi momwe ma TV amagwiritsira ntchito pofalitsa mawonekedwe a vidiyo pamwamba. Zizindikiro zimenezo zidzakhala 1080i (CBS, NBC, CW), 720p (ABC), kapena 480i malinga ndi chisankho chake, kapena malo awo ogwirizana atenga. Ndiponso, kufalitsa kwa TV 4K kuli panjira .
Kuti mumve zambiri pa 1080p ndi mapulogalamu ake ndi ma TV, tchulani nkhani yathu: Zonse Zomwe Zili pa TV 1080p .
