Chimene chithunzi chanu cha TV chimapangidwa
Mukakhala pansi ndikuwonera pulogalamu yanu kapena filimu yanu pa TV kapena kanema kanema, mukuwona zomwe zikuwoneka ngati zithunzi zowonjezereka, monga chithunzi kapena filimu. Komabe, maonekedwe akunyenga. Ngati muyang'anitsitsa TV kapena pulojekiti yowonekera, mudzawona kuti ili ndi madontho ochepa omwe ali m'mizere yopanda malire komanso yowongoka.
Chifaniziro chabwino ndi nyuzipepala yamba. Pamene tiwerenga, zikuwoneka ngati tikuwona zithunzi ndi makalata osakwatiwa, koma ngati muyang'anitsitsa, kapena mutenga galasi lopukuta mudzawona kuti makalata ndi zithunzi zili ndi madontho ang'onoang'ono.
Pixel Imatanthauza
Madontho omwe ali pa TV, makanema owonetsera kanema, pulogalamu ya PC, laputopu, kapena piritsi ndi ma smartphone, amatchulidwa ngati Pixels .
Pixel imatanthauzidwa ngati chinthu chojambula. Pikisili iliyonse imakhala ndi mauthenga ofiira, ofiira, ndi a buluu (otchedwa subpixels). Chiwerengero cha ma pixeliti omwe angathe kuwonetsedwa pawindo chimapanga chisankho cha mafano omwe akuwonetsedwa.
Kuti muwonetsetse zenizeni zowonekera, ma pixel angakonzedweratu amayenera kuthamanga pazenera pang'onopang'ono mpaka mmwamba ndi pansi pazenera, pamzere ndi mizere.
Kuti mudziwe chiwerengero cha ma pixeleri omwe akuphimba pazenera lonse, mumachulukitsa nambala ya pixelisi yopingasa mumzere umodzi ndi chiwerengero cha ma pixelisi ofanana m'mbali imodzi. Chiwerengero chonsecho chimatchedwa Kulemera kwa Pixel .
Zitsanzo za Ubale Wosakanikirana / Pixel
Nazi zitsanzo za kuchulukitsidwa kwa Pixel kwa zisankho zowonetsedwa m'ma TV lero (LCD, Plasma, OLED) ndi video projectors (LCD, DLP):
- 480i / p ikuimira 740 yopingasa x 480 pixels ofotokozera = 345,600 ma pixels onse.
- 720p imayimira 1,280 zowonjezereka x 720 pixels ofunika = 921,600 ma pixels onse.
- 768p imaimira 1,366 zowonjezera ndi 768 pixelisi ofukula = 1,049,088 pixels onse.
- 1080i / 1080p imayimira 1,920 yopingasa x 1080 pixels ofunika = 2,073,600 ma pixel onse.
- 4K ( Wowonetsera Zovomerezeka ) amaimira 3,840 pixels zowonongeka 2,160 = 8,294,400 ma pixeliti okwanira.
- 4K (Standard Cinema) amaimira 4,096 zowonjezera x 2,160 pixels ofunika = 8,847,360 ma pixel onse.
- 8K imayimira 7,680 pixels yowonongeka ndi 4,320 = 33,177,600 okwana pixels
Kuwonjezeka kwa Pixel ndi Kukula Kwawonekera
Kuphatikiza pa kuchuluka kwa pixel (chigamulo), palinso chinthu china chofunika kuganizira: kukula kwa chinsalu chomwe chikuwonetsera pixels.
Chinthu chachikulu chomwe tinganene ndi chakuti ngakhale mosasamala kwenikweni mawonekedwe a zowonetsera, kuwerengera kosasunthika / kupenya kwa pixel ndi kusakanikirana kwa pixel sikusintha pa chisankho china. Mwa kuyankhula kwina, ngati muli ndi TV 1080p, nthawizonse pamaphikseli 1,920 akuthamanga pazenera, pamzere, ndi ma pixel 1,080 akukwera ndi pansi pazenera, pamzere. Izi zimachititsa kuwerengeka kwa pixel pafupifupi 2.1 million.
Mwa kuyankhula kwina, TV ya masentimita 32 yomwe ikuwonetsera chisankho cha 1080p ili ndi mapepala angapo ofanana ndi TV 55-inch 1080p TV. Chinthu chomwecho chikugwiranso ntchito pazithunzi zowonera. Chojambula chavidiyo cha 1080p chidzawonetsera mapepala a chiwerengero chomwecho pazenera 80 kapena 200-inch.
Ma Pixels Per Inch
Komabe, ngakhale chiwerengero cha pixelisi chikhalabe chosasunthika pamtundu waukulu wa pixel pazithunzi zonse zazithunzi, kusintha ndi chiwerengero cha pixel-inch . Mwa kuyankhula kwina, ngati kukula kwawindo kumakhala kwakukulu, ma pixel omwe amadziwika payekha amayenera kukhala akuluakulu kuti akwaniritse chinsalu ndi ma pixel oyenerera pa chisankho china. Mukhozadi kuwerengetsa nambala ya pixel pa inchi yokhudzana ndi chiyanjano / kukula kwazithunzi.
Ma Pixels Per Inch - Ma TV ndi Vesi Mavidiyo
N'kofunikanso kuzindikira kuti pogwiritsa ntchito mavidiyo, ma pixel omwe amawonetsedwa pa inch for projector angapangidwe malinga ndi mawindo omwe amagwiritsidwa ntchito. Mwachilankhulo china, mosiyana ndi ma TV omwe ali ndi mazenera amphamvu (mwachilankhulo, monga ma TV-inch 50 nthawizonse amakhala ndi ma TV-inch TV), mafilimu opanga mavidiyo akhoza kusonyeza zithunzi muzithunzi zosiyana siyana, malinga ndi malingaliro a pulogalamuyo mtunda wajekesti waikidwa pawindo kapena khoma.
Kuwonjezera pamenepo, ndi ma projectors a 4K, pali njira zosiyanasiyana momwe mafano amasonyezera pawindo lomwe limakhudzanso kukula kwasankhulidwe, kuchuluka kwa pixel, ndi pixel pa ubale wa inchi.
Mfundo Yofunika Kwambiri
Ngakhale ma Pixel ndiwo maziko a momwe fano la TV likugwiritsidwira palimodzi, palinso zinthu zina zomwe zimafunika kuti muwonere zithunzi zabwino za TV kapena kanema, monga mtundu, kusiyana, ndi kuwala. Chifukwa chakuti muli ndi pixelisi zambiri, sizikutanthauza kuti mudzawona chithunzi chabwino kwambiri pa TV kapena kanema kanema.
