Thandizo la MP kumatsimikizira khalidwe la kamera
Pamene mukuyang'ana kugula kamera ya digito, chimodzi mwa zidutswa za kamera zomwe mudzawona zikuwonetsedwa ndi ojambula ndikuwonetsedwa ndi ogulitsa ndi megapixel. Ndipo zimapangitsa kukhala ndi luntha - zilembo zambiri zomwe kamera ikhoza kupereka, ziyenera kukhala zabwino. Kulondola? Tsoka ilo, ndi pamene zinthu zimayamba kusokoneza. Pitirizani kuwerenga kuti muyankhe funso: Kodi megapixel ndi chiyani?
Kufotokozera MP
Manjapixel, omwe amafupikitsidwa kukhala MP, ali ofanana ndi pixel 1 miliyoni. Pixel ndi chinthu chokha chajambula. Chiwerengero cha megapixels chimapanga chisankho cha fano, ndipo chithunzi cha digito ndi ma matepixel ambiri ali ndi kuthetsa kwakukulu. Kusintha kwapamwamba ndithudi kuli kofunika mujambula yadijito, chifukwa kumatanthauza kuti kamera imagwiritsa ntchito mapikseli ambiri kuti apange chithunzicho, chomwe chiyenera kuti chilolere kulondola molondola.
Zida Zamakono za Megapixels
Pa kamera ya digito, chithunzi chajambula chimajambula chithunzichi. Chojambula chojambula ndi chipangizo cha makompyuta chomwe chimayesa kuchuluka kwa kuwala komwe kumadutsa mu disolo ndikukantha chipu.
Zithunzi zamakono zili ndi timapepala ting'onoting'ono, zomwe zimatchedwa pixel. Zonsezi zimatha kuyeza kuwala komwe kumayambitsa chipu, kulembetsa kukula kwa kuwala. Chojambula chojambula chili ndi mamiliyoni a mapulogalamu awa, ndipo chiwerengero cha mapulogalamu (kapena pixels) chimawerengetsera zilembo zamakono zomwe kamera ikhoza kuzilemba, zimatchedwanso kuchuluka kwa chisankho.
Kupewa MP Kusokonezeka
Apa ndi pamene zinthu zimakhala zovuta pang'ono. Ngakhale zili bwino kuti kamera yokhala ndi maijapixel 30 iyenera kukhala ndi khalidwe labwino kuposa kamera yomwe ingalembedwe majegixel 20 , sizinali choncho. Kukula kwake kwa chithunzi chachithunzi chimagwira ntchito yofunika kwambiri pakuzindikiritsa khalidwe la kamera inayake.
Taganizirani izi motere. Chojambulira chachikulu chachithunzi mu kukula kwake komwe kuli 20MP chidzakhala ndi zikuluzikulu zapamwamba zowonjezera pazomwezi, pomwe pang'onopang'ono chojambulira chithunzi chomwe chili ndi 30MP chidzakhala ndi tinthu tating'onoting'ono tomwe timapanga.
Chikumbumtima chowala chachikulu, kapena pixel, chidzatha kuyeza molondola kuwala kolowera ku lens kumaloko kusiyana ndi kulandira kuwala pang'ono. Chifukwa cha zopanda chilungamo pakuyeza kuwala ndi pixel yaing'ono, mudzatha ndi zolakwika zambiri, zomwe zimadzetsa "phokoso" mu fano. Misewu ndi mapikseli omwe samawoneka ngati mtundu woyenera mu chithunzi.
Kuonjezera apo, pamene mapikseliwo ali pafupi, monga ali ndi kachidutswa kakang'ono ka chithunzi, ndizotheka kuti zizindikiro zamagetsi zomwe pixelini zimapanga zimatha kusokonezana wina ndi mnzake, zomwe zimachititsa zolakwitsa muyeso.
Choncho ngakhale chiwerengero cha makina opangira mafilimu omwe amatha kujambula amachititsa chidwi pa khalidwe la zithunzi, kukula kwake kwachithunzi kumagwira ntchito yaikulu. Mwachitsanzo, Nikon D810 ili ndi majegixix 36 a kuthetseratu, komanso imapereka chithunzi chachikulu kwambiri, choncho chimakhala chabwino kwambiri pa dziko lonse lapansi.
Kusintha MP Settings
Makamera ambiri a digito amakupatsani mwayi wosintha chiwerengero cha megapixels zomwe zalembedwa mu chithunzi china. Kotero ngati kuthetsa kwa kamera kwasintha ndi 20MP, mukhoza kulemba zithunzi zomwe ziri 12MP, 8MP, 6MP, ndi 0.3MP.
Ngakhale kuti simukulimbikitsidwa kuti mujambula zithunzi ndi zojambulajambula zochepa, ngati mukufuna kutsimikizira chithunzi cha digito chomwe chidzafuna malo osungirako osungirako malo, mudzawombera pamapangidwe apansi a megapixel, monga kujambula ndi maixapixels angapo kapena Chisankho chachikulu chimafuna malo osungirako.
