Dab tsi tus neeg pom ntawm lub tsom iav lossis TV, hauv ntawv xov xwm lossis duab xim yog duab tsim los ntawm ntau lab me me ntawm cov xim sib txawv. Cov no yog cov pixels. Lo lus no yog siv thoob plaws hauv kev ua haujlwm hauv engineering, typography, thiab programming. Txhua cov duab khaws tseg rau hauv lub koos pij tawj lossis digital lub koob yees duab, thiab txawm tias txhua tus duab ntawm lub vis dis aus, nws ua los ntawm cov pixels.
Pixel (Pixel) - lub tswvyim uas sawv hauv kev txhim kho ntawm cov thev naus laus zis. Nws yog cov ntawv luv ntawm ob lo lus duab thiab ntawm tes thiab txhais qhov tsawg kawg nkaus uas ua rau nce mentsis. Cov ntsiab lus no yog siv dav hauv kev siv tshuab thiab kev kawm ua haujlwm.
Cov duab ntawm tus saib thiab hauv cov ntawv luam tawm tau hais meej nyob rau hauv daim ntawv ntawm cov npib cais - pixels. Qhov loj ntawm cov duab raster qhia hauv pes tsawg tus pixels ib qhov siab thiab dav ntawm daim duab, piv txwv li, 1680x1050, thiab yog hu ua qhov kev daws teeb meem.
Pixels rau ntawm lub ntsuas vaj huam sib luag
Yog tias koj ua tib zoo saib ntawm lub ntsuas vaj huam sib luag, koj tuaj yeem pom cov xim me me cov xim phom sij. Daim duab yog tsim los ntawm lawv. Ib qho pixel cais ntawm cov ntsuas yog tsim los ntawm ib pawg subpixels ntawm peb thawj xim: liab, ntsuab, xiav. Cov cuab yeej kho vajtse ntawm cov ntsuas tau txais cov ntaub ntawv los ntawm PC txog lub pixel xim, qhov ci ci thiab qhov siv, ntawm lub hauv paus uas nws txiav txim siab seb cov nuj nqi twg subpixels yuav tsum muaj. Tom qab ntawd, tswj cov cim raug xa mus rau hauv matrix, thiab nyob rau qee lub sijhawm cov xim xav tau twb pom lawm. Tib yam mus rau ntshav TVs.
Cov ntsuas qub CRT tseem yuav tsim ib daim duab los ntawm kev ua cov pixel raws li pab pawg ntawm subpixels ntawm peb thawj xim. Tsuas yog hauv cov version no, ib lub pixel tuaj yeem tsis yog ib qho, tab sis ntau qhov subpixels ntawm xim liab, ntsuab thiab xiav xim.
Qhov ua tau zoo ntawm LCD saib yog txiav txim siab los ntawm qhov tseeb hais tias ib tus pixel cais ntawm lub ntsuas vaj huam sib luag raug faib rau txhua qhov tso tawm pixel. Qhov no tshem tawm cov txiaj ntsig tsis zoo ntawm moiré, qhov sib txawv ntawm qhov loj me ntawm txhua pixel.
Pixels hauv kev thaij duab digital
Txhua cov duab khaws tseg digitally yog qhov sib npaug ntawm pixels thiab qhov muaj nuj nqis ntawm cov xim, kev saturation thiab ci ci rau lawv txhua tus. Yog tias, thaum saib daim duab, sim ua kom dav rau hauv PC saib ntau li ntau tau, koj tuaj yeem pom cov pixels, uas yog cov duab plaub fab nrog ib qho xim. Tsis muaj kev hloov pauv xim nyob sab hauv lub xwmfab, thiab tsuas yog thaum tshem tawm, thaum phav phav nyob sib ze nrog cov duab zoo heev nyob hauv qhov chaw pom, tib neeg lub qhov muag pom kev hloov pauv xim thiab pom qhov txawv cov khoom uas tau yees duab, tsis them sai sai rau txhua pixel sib cais.
Qhov ntau tsawg dua cov pixels yog, qhov ntau dua-zoo cov duab ua los ntawm lawv yuav tshwm rau tus neeg. Tus naj npawb ntawm pixels ib square nti yog tus yam ntxwv ntawm qhov zoo ntawm kev thaij duab, lub ntsej muag ntawm tus saib lossis lub xov tooj smartphone.
Kev ua Bitmap koom nrog ib tus neeg pixels los yog pab pawg ntawm pixels. Los ntawm hloov lawv cov xim thiab qhov ci, koj tuaj yeem tsim ib daim duab tshiab lossis hloov ib daim duab uas twb muaj lawm.
