Kuyini ngephikseli?

A yephikseli yokukala kwesikrini kwanoma iyiphi qapha yesimanje, kungaba i-computer, i-laptop, umakhalekhukhwini, navigation nokunye. Ngamanye amazwi, umbuzo kuyini ngephikseli, zingaphendulwa, kumane iphuzu. Okungukuthi, uma bethi ubukhulu isithombe Amaphikseli 100 x 30, ukuze umfanekiso siqukethe Amaphikseli 100 x 30. Ngakho, ubukhulu yephikseli iphuzu elilodwa qapha ikhompyutha yakho noma kwenye idivaysi. Pixels kungenzeka omnyama nomhlophe noma umbala. Siyabonga kubo, nokukhohlisa ukukhanya, ungakwazi ukufinyelela kwesakho, upende, ukwakha ezihlukahlukene ihluzo, hlela izithombe, umbono eziyizintandokazi zakho movie.

Amaphikseli asetshenziswa ukulinganisa isinqumo wesingameli sakho. Kukhula inani Amaphikseli abakwazi ukubonakalisa idivayisi yakho, isithombe libukhali kangcono izobukeka. Ngo nomklamo wewebhu, bajwayele akhombise isayizi izithombe, izithombe, nobe nguyiphi intfo yinye, itafula amaseli. Ngenxa yale njongo nemingcele ezifana ukuphakama nobubanzi yesithombe.

Manje unalo ulwazi jikelele ukuthi yephikseli. Kodwa manje singathanda ukuba aphenye ngalesi umqondo kabanzi.

Imisuka Imininingwane kwe-pixel

kwe-pixel ngalinye kuhlanganisa ilwazi izinto ezinhlanu. Ababili babo banesibopho izixhumanisi the pixel, okungukuthi, indawo yayo kokubili thwi kanye nendawo. Abanye abathathu banesibopho umbala. Yizo ezinquma ukukhanya ingase ibe nombala obomvu, oluhlaza okwesibhakabhaka kanye oluhlaza. Lezi zici ezinhlanu sihlanganise ukunikeza umfundi ithuba uqede indawo oyifunayo esikrinini futhi ukunquma umbala wayo elungile. Bebonke bakha pixels ku ifreyimu kwesikrini.

Megapixel - ingenye ayisigidi adala wonke isithombe. Njengomthetho, megapixels zisetshenziselwa ukukala usayizi photo, isithombe, ividiyo.

Iyini i-pixel ye "ile" futhi "Wanamathela"?

Ngokuqinisekile, uke wawezwa la eside Amaphikseli "ile". Sizama ukuba baqonde ukuthi kusho. Ukuze uqale nge siyowuqonda, kuyini LCDs. I-matrix qapha has inqwaba zinhlayiya ngamunye olawula mncane ifilimu Transistor. Kuleso simo, uma mncane ifilimu Transistor uyeke ukusebenza kahle, ukuthi uphumile emgqeni, ngaleso indawo uboniswa yesithombe izoba. Vele kunjalo kukhona Amaphikseli "ephukile" efonini, qapha ikhamera, i-laptop noma ikhompyutha. Lolu hlobo yephikseli nzima kakhulu ukulungisa futhi iyingozi imishini.

Kufanele athi ngaso sonke isikhathi i-non-ukusebenza kwe-pixel okungukuthi omnyama, njengoba i-pixel ye - okungukuthi iqoqo 3 sub-Amaphikseli - blue, oluhlaza nobomvu. Ushintsho umbala ibangelwa ligijima crystal. Uma lokhu crystal simile, kuyoba ukubonisa kuphela umbala ngokushintsha isithombe ukuthi 'ngci ". Ngokuvamile Amaphikseli "Wanamathela" bamane awuboni. Ukuqeda le nkinga kungenzeka esebenzisa isimiso esikhethekile kanye nomthelela othile, ngisho ekhaya.

Kukhona futhi ezinye izinhlobo Amaphikseli, njengokuthi "engaphansi" futhi "hot". Empeleni, lokhu ukushintshashintsha Amaphikseli eziphukile, okuzokwenza ukuzibonakalisa ngaphansi kwezimo ezithile. Ngo-movie, imidlalo, ukusebenza ngemifanekiso Ngezikhathi ezinjalo, kungenzeka ahlale kuyivelakancane ukuba iso.

Manje uyazi ukuthi yephikseli nekutsi isebenta njani. Futhi khumbula ukuthi uma kwenzeka ukwehluleka, okusho "ile" noma Amaphikseli "Wanamathela", kungcono ukuya ngqo inkampani ezikhethekile ukulungisa, uma kungenzeka, kudivayisi yakho ukuze baphile isikhathi eside. Phela, akekho othanda ukubheka amachashazi amnyama esikhundleni izithombe amahle.
