Izvi zvinoreva kuti iyo mapikiseti 1,920 inorongwa mumitsetse yakatarisa iyo inodarika muhwindo kubva kuruboshwe kuenda kurudyi (kana kurudyi kuenda kuruboshwe kana uchida), asi ma-pixels 1,080 akarongerwa mumitsara kana mitsara, inobva kumusoro kusvika pasi kwechiso chepamusoro . 1,080 (iyo inonzi inogadziriswa yakagadziriswa - sezvo kuguma kwemutsara wepikisi mumwe nomumwe uri kuruboshwe uye kurudyi kwechirwisi) ndiko kuti chikamu che1080 chezwi 1080p chinobva.
The Total Number Of Pixels Muna 1080p
Iwe unogona kufunga kuti 1,920 pixels inoratidzwa pahwindo, uye 1,080 pixels inotangira kubva kumusoro kusvika pasi, haisi kunyatsoita sezvakawanda. Zvisinei, paunowedzera nhamba yemapikseli kumativi ose (1920) uye pasi (1080), inokwana 2,073 600. Iyi ndiyo nhamba yose yepikseli inoratidzwa pachikona. Mumiririri yemakamera / mafirimu, izvi zvinenge 2 Megapixels. Izvi zvinotumidzwa sePixel Density.
Zvisinei, nepo nhamba yemapikiseli isiri yakafanana pasinei nehuwandu hwemahwindo, nhamba yepikisiki-per-inch inoshandiswa sechishandura mashizha anochinja .
Apo 1080p Inopindira
1080p inofungidzirwa pedyo nepamusoro pevhidhiyo yakagadziriswa kunaka kwekushandiswa mumaTV nemavhidhiyo emagetsi (ikozvino 4K ndiyo yakakwirira-yakaenzana ne8,3 megapixel ), haibati kenduru kumhinduro ye megapixel kunyange yakawanda yemadhijidhi asingadhuri achiri makamera. Chikonzero cheizvi ndechokuti zvinotora zvakawanda zvakawanda zvishoma nezvishoma uye kushandiswa kwesimba kuti kuve nemifananidzo inofamba kupfuura mifananidzo, uye ikozvino, iyo yakagadziriswa yevhidhiyo yakagadziriswa inogona kushandiswa kuburikidza nekambani yemagetsi ndeye 8K, iyo inopedzisira yava kusvika padhijitari ichigadziriswa makamera 33.2 megapixel ). Zvisinei, ichave iine makore mashomanana tisati taona maTV 8K sechinhu chinowanzogadzirwa kune vatengi.
Apa inouya I & # 34; P & # 34; Chikamu
Zvakanaka, ikozvino kuti une pixel chikamu che1080p pasi, zvakadini neP pane? Icho chinonzi P inomiririra chiri kufambira mberi. Aiwa, haina chokuita nezvematongerwo enyika asi ane chokuita nemaonero anoita pixel (kana mitsara) paTV kana kuti mavhidhiyo ekuratidzira. Apo chifananidzo chinoratidzwa zvishoma nezvishoma, zvinoreva kuti mitsetse yepikseli yose inoratidzwa pachikwangwani sequentially (imwe pashure pomumwe mukuverengwa kweunhamba).
Iko 1080p inosangana neTV
1080p chikamu cheHigh-Definition video standards landscape. Somuenzaniso, HDTVs, kunyanya iyo inenge masendimita makumi matanhatu kana masere , inosvika 1080p yemuenzaniso (kana pixel) kusarudzwa (kunyange zvazvo kuwedzera kwenhamba ikozvino 4K Ultra HD TVs).
Izvi zvinoreva kuti kana iwe uchiisa mutsara muTV 1080p ine sarudzo yepasi pe1080p, TV ichafanirwa kushandura iyo chiratidzo kuitira kuti ichataridza mufananidzo pane yose yekona yepamusoro. Izvi zvinotumidzwa seUpscaling .
Izvi zvinoreva zvakare kuti zviratidzo zvekushandisa nechepasi pe1080p chisarudzo hazvizoita zvakanaka sechokwadi chechokwadi yepikicha yevideo 1080p nokuti TV inofanira kuzadza izvo zvingafunga kuti hazviitiki. Nezvifananidzo zvinofamba, izvi zvinogona kuita kuti zvinhu zvisingadiwi zvakadai semakakatanwa, mavara eropa, macroblocking, uye pixelation (izvi ndizvo zviripo kana uchitamba maVHS akare matepi!). Kunyanya kufungidzira kuti TV inogadzira, zviri nani mufananidzo unotarisa. Ita TV haifaniri kuva nechinetso nemichina ye 1080p inopinza, yakadai seyaya kubva kuBlu-ray Disc, nekushambadzira / kabato / satanese mazano anogona kupa zviyero muna 1080p.
Purogiramu yepaTV ndiyo imwe nyaya.
