Luhlobo luni lwesibuko yikhamera yokucupha, kwaye
uthini umgaqo?
Ikhamera yokucupha ilingana nelensi yeconvex.
Ngenxa yokuba ikhamera yayo yenziwe liqela leelens, umsebenzi wayo uyafana nowe-convex lens, oko kukuthi, ukuvumela izinto ezikude (ngaphaya kwamaxesha ama-2 ubude bomgqaliselo) ukuba zifanekiselwe kwi-sensor emva kokudlula kwi-lens (ukunciphisa). umfanekiso wokwenyani).
Umgaqo wokusebenza wekhamera ngokumalunga ngolu hlobo lulandelayo: umfanekiso obonakalayo owenziwe ngumbono nge-lens (LENS) uqikelelwa phezu kobuso bomfanekiso womfanekiso, uze uguqulwe ube ngumqondiso wombane, oguqulwa ube ngumqondiso wedijithali. emva kwe-A/D (ukuguqulwa kwe-analog-to-digital), kwaye emva koko ithunyelwe kwisignali yedijithali.Icutshungulwa kwi-chip ye-signal processing (DSP), kwaye emva koko idluliselwe kwikhompyutheni ukuze iqhutywe nge-interface ye-USB, kwaye umfanekiso unokubonwa ngemonitha.

Isicelo
iliso lomntu
Ngaba umfanekiso owenziwe ngamehlo omntu wokwenyani okanye wenyani?Siyazi ukuba ukwakheka kweliso lomntu lilingana ne-convex lens, ngoko ke umfanekiso wezinto zangaphandle kwi-retina kufuneka ube ngumfanekiso wokwenyani.Ngokwalo mthetho wamandla ongasentla, umfanekiso okwiretina ubonakala ujijekile.
Ngaba yiyo nayiphi na into esiqhele ukuyibona, ecacileyo ukuba ithe tye?Oku kungquzulana namava kunye nemithetho ngokwenene kubandakanya umsebenzi wohlengahlengiso lwe-cerebral cortex kunye nefuthe lamava obomi.Ngenxa yempazamo ebonakalayo, iliso lomntu likholelwa ukuba ukukhanya kukhutshwa yinto kwaye iqondiswe kwiliso lomntu.
Xa umgama phakathi kwento kunye ne-convex lens mkhulu kunobude bojoliso belensi, into leyo yenza umfanekiso oguqulweyo.Xa into isondela kwilensi ikude, umfanekiso uya uba mkhulu, kwaye umgama ukusuka kumfanekiso ukuya kwilensi nawo uyanda ngokuthe ngcembe.
Xa umgama phakathi kwento kunye ne-lens incinci kunobude obugxininisekile, into leyo iba ngumfanekiso owandisiweyo, ongeyiyo indawo yokuguqula yemitha ye-refracted eyiyo, kodwa indawo yokuhlangana yemigca yabo yokwandisa umva, engenakufunyanwa ngu. isikrini sokukhanya kwaye ngumfanekiso obonakalayo.Ukuchasana nomfanekiso obonakalayo owenziwe sisibuko senqwelomoya (awukwazi ukufunyanwa sisikrini sokukhanya, sinokubonwa kuphela ngamehlo).
Ikhamera
Ilensi yekhamera yilensi yeconvex, indawo ekufuneka ifotwe yinto, kwaye ifilimu sisikhusi.Ukukhanya kwe-radiated kwi-into isasazeka kwaye ibonakaliswe nge-convex lens ukwenza umfanekiso wento kwifilimu yokugqibela;ifilimu igqunywe ngomqolo wezinto ezibuthathaka kukukhanya, ezithi zitshintshe iikhemikhali emva kokuvezwa, kwaye umfanekiso wento urekhodwe kwifilimu.
Unxulumano phakathi komgama wento kunye nomgama womfanekiso ufana ncam nolo lwelensi yeconvex.Xa into isondele, umfanekiso uba kude nangaphezulu, ube mkhulu kwaye ube mkhulu, kwaye ekugqibeleni ube ngumfanekiso wenyani kwicala elinye.Xa umgama wezinto ukhula, umgama womfanekiso uyancipha, kwaye umfanekiso uba mncinci;xa umgama wezinto uyancipha, umgama womfanekiso uyanda, kwaye umfanekiso uba mkhulu.Ngexesha elinye ubude bojoliso buhlulwe ngokwenyani kunye nenyani, kwaye amaxesha amabini ubude bojoliso bohlulwe ngokwesayizi.
enye
Iilensi zeconvex zisetyenziswa kwiiprojektha, iiprojektha zesilayidi, iiprojektha, iindondo zokukhulisa, izibane zokukhangela, iikhamera kunye neekhamera.Iilensi zeConvex zigqibelele ubomi bethu kwaye zisetyenziswa kubomi bethu ngalo lonke ixesha.Iiglasi ezibona kude ziilensi eziconvex, yaye iindondo ezibona kufutshane ziilensi eziphokophekileyo.
