MP Kubatsira Tsvaga Kamera yeKamera
Sezvauri kutsvaga kutenga kamera ye digital, imwe yezvidimbu zvakajairika zvekhamera mubhuku uchaona zvose zvakagadzirwa nevakagadziri uye zvinoratidzwa nevatengesi ndiyo megapixel. Uye zvinogadzira zvishoma - majegapixels akawanda kamera inogona kupa, zviri nani zvinofanira kuva. Rudyi? Zvinosuruvarisa, ndiko kuti zvinhu zvinotanga kuve zvikavhiringidza. Ramba uchiverenga kuti upindure mubvunzo uyu: Chii chinonzi megapixel?
Kusarudzira MP
I megapixel, kazhinji inopfupiswa kuPP, inokwana miriyoni imwe pixels. A pixel inhengo yechinhu chechidimbu. Nhamba ye megapixels inosarudza kugadzirisa kwechifananidzo, uye chifananidzo che digital chinowedzera maegapixels ine sarudzo yakawanda. Chigadziriswe chepamusoro zvechokwadi chinodikanwa mumifananidzo ye digital, sezvo zvinoreva kamera inoshandisa mamwe mapikiseti kuti aumbe chifananidzo, icho chinofanira kubvumirwa kuti chibvumirwe kunyatsoruramisa.
The Technical Aspects of Megapixels
Pane kamera ye digital, sensor image inonyora mufananidzo. Chigadzirwa chemufananidzo chigadzirwa chemakombiyuta chinoyera chiyero chechiedza chinotenderera kuburikidza ne-lens ndokurova chip.
Zviratidzo zvemufananidzo zvine zvinyorwa zviduku, izvo zvinonzi pixels. Chimwe chezvinhu izvi zvinogadzirisa zvinogona kuyera chiedza chinoputika chip, nekunyora kushanda kwechiedza. Chigadzirwa chemufananidzo chine mamiriyoni ezvo zvinogamuchirwa, uye nhamba yezvinyorwa (kana kuti pixels) inotara nhamba ye megapixels iyo kamera inogona kutora, inonziwo yakawanda yekugadzirisa.
Kudzivisa MP Kusanganiswa
Apa ndipo pane zvinhu zvinowanikwa zvishoma. Kunyange zvazvo zvichitarisira kufunga kuti kamera ine megapixel 30 inofanira kubereka zviri nani mufananidzo wepamusoro pane kamera inogona kutora megapixel 20 , haisi nguva dzose. Ukuru hwemufananidzo wechitinha chechifananidzo chinotora basa rinokosha pakugadzirisa unhu hwemufananidzo wemamwe makamera.
Funga nezvazvo nenzira iyi. Chirwere chikuru chechifananidzo mumasikirwo emasikirwo ane 20MP chichava nemamwe makuru ekugamuchira chiedza pane iyo, nepo mufananidzo wechidiki muhukuru hwemuviri huine 30MP huchava nediki chaizvo chiedza chekugamuchira.
Chikumbaridzo chechiedza chikuru, kana pixel, chichakwanisa kunyatsonyatsojekesa chiedza chinopinda mu lens kubva munzvimbo yacho pane kechidiki chekugamuchira chiedza. Nemhaka yezvisina kururama mukuyera chiedza ne pixel shomanana, iwe uchagumisa nezvikanganiso zvakawanda muyero, zvichiguma ne "ruzha" mumufananidzo. Mheremhere mapikisiki asingaoneki semuvara wakakodzera mumufananidzo.
Uyezve, apo pikiselini yega yega iri pedyo, pamwe sezvavari nechinomwe chemufananidzo, zvinogona kuti zviratidzo zvemagetsi izvo mapikisesi anogadzira zvinogona kupindirana, zvichikonzera kukanganisa muyero hwechiedza.
Saka nepo nhamba ye megapixels kamera inogona kunyora inobata basa muhupamhi hwemufananidzo, chimiro chemuviri chemufananidzo wechitema chinotora basa guru. Semuenzaniso, Nikon D810 ine megapixel 36 ekugadzirisa, asi inopawo hurukuro huru yemufananidzo, saka ine yakanakisisa yezvose zviri zviviri.
Kuchinja MP Settings
Kazhinji makamera echidimbu anokupa sarudzo yekuchinja nhamba ye megapixels yakanyorwa mune imwe mufananidzo. Saka kana ikasarudzo yekugadzirisa yekamera iri 20MP, unogona kunyora mifananidzo iri 12MP, 8MP, 6MP, uye 0.3MP.
Kunyange zvazvo zvisingawanzobvumirwi kutora mapikicha nemaegapixel mashomanana, kana uchida kuisa chinyorwa chidijicha chinoda chikamu chakachengetwa chekuchengetedza nzvimbo, iwe uchapfura panzvimbo yakadzika ye megapixel, sekunyora nekawanda ye megapixels kana pa chigadziro chikuru chinoda nzvimbo yekuchengetedza yakawanda.
