Kuyini qapha kokuhlola Amaphikseli efile?

Namuhla, ubuchwepheshe ivela ngejubane umbani. Kunengqondo, izolo wasebenzisa imali usomqulu, futhi namuhla akunakwenzeka ukucabanga ukuphila ngaphandle amakhompyutha nasezintweni zobuchwepheshe zamuva. Nsuku zonke kukhona onobuhle entsha mobile phones, ama-scanner nama-laptops, amaphilisi, futhi-ke, ukuqapha ku-PC yakho. Ngaphambili, i-computer okusekelwe ubuchwepheshe of cathode ray amashubhu. Manje - isikhathi LCD Abaqaphi.

Man ukwenza ngcono begodu ziphumelele emncintiswaneni ngenxa ezintsha emhlabeni ubuchwepheshe. Sichitha imali eningi ukuze kuthuthukiswe zabo electronic "abangane." Ngakho uthenga qapha cool bese uqale ukuhlola ke. Buka ama-movie, e-course imidlalo, njll Ngenxa yalokho, ubona amachashazi ongaziwa emnyama noma emhlophe esikrinini ezivimbela ukuthi ubukele amafilimu zakho ozithandayo. Lokhu kungapheleli emhlabeni-computer okuthiwa "i-pixel ye efile". Ake sibone ukuthi yini uhlobo kuhlasela futhi kanjani ukulwa naso.

Okokuqala, kungase kudingeke uqonde ngokucacile kuyini ngephikseli. Abaqaphi Modern ukukhiqiza kabusha izithombe sibonga zobuchwepheshe matrices. Isithombe esikrinini yakhiwa sebuningini amaphuzu okuyinto ngokuvamile kuthiwa pixels. lokhu kuyizinhlayiyana-matrix encane kuhlanganisa subpixels amathathu uthini: obomvu, omnyama oluhlaza. Esikhathini okuthiwa asebenzayo-matrix kwe-pixel umsebenzi usebenzisa TFTs. Uma idivayisi ehluleka, kukhona iphuzu ngasebenzi amnyama akashintshi umbala uma ukushintsha isithombe. Lokhu sinqamukile piksel.Danny uhlobo izinkinga zingaxazululeka kuphela ezimweni ezikhethekile laboratory.

Kunenye uhlobo iphutha Amaphikseli - "Wanamathela" iphuzu. Kulokhu, kukhona ibala elikhanyayo ku nengemuva elimnyama ngokuphelele. Isizathu esiyinhloko - kungcono jam omunye sub-Amaphikseli ezintathu. Lolu hlobo lwesici ingabuyiswa ekhaya. amachashazi Black ezidinga ukuthi kungenelelwe phezu ingxenye ochwepheshe.

Kukhona ngempela umbuzo esinengqondo: "? Kanjani ukuhlola qapha ku Amaphikseli efile" Yiqiniso, ukucacisa isici iso cishe kungenakwenzeka. Noma yimuphi yomthengisi izokubonisa esikrinini elikhanyayo isithombe esinemibala hhayi usihlole ku ezingefani. Ngakho eyenziwa qapha kokuhlola Amaphikseli engaphelele. Udinga ukuqonda ukuthi le nkinga kuzibonakalisa ezingefani. Okungukuthi, abangabantwana ichashaza elibomvu kuzobonakala ku ithoni oluhlaza, njll Ngakho ukubonisa ukuphikelela nokuqaphela lapho uthenga izimpahla. Phela, yesimanje computer kusho ukulahlekelwa imali.

Ngokuyinhloko ukuqapha kokuhlola Amaphikseli engaphelele Kwenziwa esebenzisa izinhlelo ezikhethekile. ethandwa kakhulu ngezidingo Nokia Gada Test. Uhlelo kulula ukuyisebenzisa. Ukhetha umbala imodi scan bese uvula ukuhlolwa isikrini sakho usebenzisa ezihlukahlukene. Uma uya ukuthenga qapha entsha, ukuqopha Umbuso kudiski futhi enze ukuhlola esitolo. Ngakho, uyoba umshwalense uma ukungasebenzi. Eqinisweni, qapha kokuhlola Amaphikseli engaphelele - inqubo aphansi ukuthi akuthathi isikhathi sakho esiningi.

Kukhona izinhlelo eziningi, lapho uphethwe wenziwa. Ngokwesibonelo, ukuqapha uvivinye Amaphikseli efile Kwenziwa ngosizo izinhlelo ezikhethekile - Gada Test 1,52. Pretty elula ukusebenzisa Umbuso indawo ikuvumela qualitatively ukuxilonga izinkinga ezihlobene ne-matrix.

Ngeshwa, zikhona Amaphikseli ezonakele matrices aphathekayo kanye amaphilisi. Lokhu kungapheleli sizalwa nawo cishe yonke inguqulo Isabelomali qapha. Kube kwezinkambiso kuvunyelwe ukuthi ucacise lemali lolu hlobo iphutha. Cishe zonke izitolo ukunikela ngaphezu isiqinisekiso eyinhloko okubizwa ngokuthi Zero Bright Dot. Nge lokhu kwakwenqatshelwe ikhasimende unelungelo ukubuyela qapha, uma ukuthola okungezona eduze Amaphikseli okungenani ezinhlanu efile. Ngaphambi kokuba uthenge kungcono ukuthatha isinyathelo ukuze uphephe. Lokhu kuzokusiza ukuhlola qapha ku pixels engaphelele. Ngemva izimpahla zinokukhubazeka uthenga eyodwa ngeke iqhubeke.
