Ikamera vanogadzira vanoda kuparidzira makamera nenhamba ye megapixels yavanazvo. Asi chii chaizvo chinonzi megapixel uye chinosvibisa sei mifananidzo?
I megapixel ine pixel 1 mamiriyoni. Pixels mapoka maduku akaiswa pamwechete sezvikamu zvepikicha kana mifananidzo kuti uite mafoto ako. Kugadzirisa kwemufananidzo wako kuchagadziriswa munzvimbo huru nekuwanda kwezvikwereti zviduku zvakakonzerwa pamwe chete munzvimbo duku.
Ikamera ye8 megapixel (8MP) inenge ine mamiriyoni masere emakona mashomanana eminamita pamasendikiti apo kamera yekhamera pa 1.5 megapixels (1.5MP) inenge ine mamiriyoni ezvikamu zvigadziro zvemashoko mu inch.
Saka izvi zvinorevei kumifananidzo yako?
Zvinyorwa zvishoma, ruzivo rwakanyanya ruzivo. Kana humwe ruzivo rwakanyatsopindirwa mune imwe nzvimbo, zviri nani maziso edu akabatanidza mitsetse pamwe chete kuti agadzire mufananidzo wakazara. Kana ruzivo ruduku ruzhinji ruwanika ziso rinotarisa mhiri dzakatemwa dzemapikiseli apo pavanosangana nazvo, sezvamunoona nzvimbo imwe neimwe yezvigadzirwa zvemairai. Iyo yakagamuchirwa "mizinga" yekudhinda mifananidzo ikozvino 300dpi (madotsiti nemaawa inch). Kunyange zvazvo madhishi nehombodo imwe neimwe haisi yepamusoro yakangofanana nemapikiseti pamasendimisi musiyano hauchakuvhiringidzi mumazuva ako zuva nezuva photo kutora / kudhinda.
Ndezvipi zvakawanda zvandinoda?
Kuti uone kuti ruzivo rukuru rwunoda humwe huwandu hwemashoko hukuru hwaunoda hunoita huwandisa hukuru hwepachirongwa nechisarudzo chaunoda.
Somuenzaniso, ne 300dpi kutonga mupfungwa, kudhinda mufananidzo we8x10 waunoda 2400 pixels ne 3000 pixels ye ruzivo. Kana iwe uri kuratidza mufananidzo pane internet (apo 72 pixels pamasendiki anogamuchirwa) iwe ungangoda 576 pixels ne 720 pixels.
Saka ndingadi kangani megapixels?
Ikamera imwe neimwe inoratidza dhidhiyo muhutano hwakasiyana asi kune mamwe "mitemo yegumbo" iwe unogona kutevera.
Sarudza kuti chii chakakura zvikuru chimiro chaunoda kudhinda. Kune vanhu vakawanda izvi zvichava mufananidzo we8x10. Sarudza nhamba yemapiksesi inodiwa kwekudhinda 300dpi (2400x3000 ye 8x10). Zvadaro wedzerai pixel mbiri yakaenzana pamwechete. Kune 8x10 izvi zvinosvika 7.2 mamirikisi mapikisi, kana 7.2 megapixel. Iyi ndiyo nhamba inosarudzwa yePP iwe unoda kana 8x10 kudhindwa ndicho chikuru pane zvingadhindwa.
