Camera matrix

abasebenzisi Russian aveza kuthandwa digital kunye neekhamera. Yonke imihla, abenzi lwehlabathi ukuvelisa imifuziselo ezintsha, kubonelelwe ngamathuba ngakumbi nangakumbi iifoto. Namhlanje, umntu avareji kunokuba nzima ukujonga ukhetho lwecamera. Ngamanye amaxesha abanamava salespeople evenkileni kwaye akanako ukunika abazikhethele yakhe yamatyala ecacileyo. Kungenxa yoko le nto ngumthandi ukufota, kwaye nangakumbi ngoko umsebenzi kufuneka bazi ezinye iimpawu kunye neempawu kwezixhobo zale mihla.

Le khamera matrix yenye yezinto ezibalulekileyo izixhobo ezinjalo. It is a isixhobo isivamvo kunye uvakalelo oluphezulu, nto leyo ukuqinisekisa uguqulo kumfanekiso woqondo kumntu phezu ilens, ukuba umqondiso yedijithali. ikhamera okanye matrix ikhamera kunefuthe elingqalileyo drill kunye nomgangatho imifanekiso. Makhe sihlolisise oko nesiqalelo.

yedijithali camera matrix uquka ezininzi izinto ukukhanya ethe, ukuguqulela umfanekiso enombala zibe yombane. pixel nganye ukhandwa nemakhadi matrix yomfanekiso lokugqibela. Nasekumeni zabo yohlulwe ngokupheleleyo-isakhelo, scan progressive, elinomhlathi ehlangule isakhelo kumthamo ingxelo umsi kunye interlaced. Kulo mzekelo, isizalo lungohlulwa lube iintlobo ezimbini eziphambili, ezo ngoku ifumaneka ngalo iikhamera bathengisa.

Types of khamera matrices

Kangangexesha elide siye isetyenziswe neethemplethi angqinelanayo semiconductors metal oxide (iCMOs), ogama uvakalelo ukukhanya lwafumaneka kwi gqira. Apha, i readout uphawu kungenziwa kuyo nayiphi na indawo, wena kudingeka nje ukuba ukhankanye umqolo kunye column. Ngaloo pixel nganye msindo uphawu yokufunda. Emva kwethutyana kwakukho ngezixhobo waba isixhobo isigxina-kukhatshwa (CCD), nto leyo kwasekuqaleni baba mkhulu kakhulu iCMOs-matrix. Kwiinkqubo ezinjalo, ukufunda uphawu isebenze ngendlela efanayo CRT (cathode ray tube), ngamanye amazwi ukusuka ekhohlo ukuya ngasekunene yaye siqala phezulu ukuya ezantsi. photodiodes Silicon baba kulo mzekelo njengezinto photosensitive. Ekupheleni koo-yokuqala yavelisa ukuphucuka okukhulu iCMOs-woluvo. Ngenxa yokuba izinto ezinjalo olu hlobo matrices kangangoko ukufumana uvakalelo yesiqhelo kunye nomgangatho ophezulu umfanekiso kuphela matrices isikali kakhulu ukuba esetyenziswa iikhamera zobungcali kunye nemilinganiselo elikhulu. Ukuba sithetha imifuziselo manqindi engahlawulwayo efikelelekayo, kungcono ukukhetha kwabo mayixhotyiswe CCD matrix. Iinkampani ezifana neekhamera Canon ne Nikon avelisa onobuhle kancincane iCMOs-isizalo, kuba luhlobo isicwangciso yenguqu.

Matrix camera enje iimpawu ezibalulekileyo njengoko isisombululo. Phantsi sigqibo kubhekisela kwinani lweziqalelo zibuthathaka matrix, nganye wamkela ukukhanya iyiguqule ibe ethile ityala lombane. Kubalulekile ukuqonda ukuba ayenzi ingqiqo ukugxotha inani pixels njengoko umgangatho imifanekiso eshicilelweyo na twatse, kwaye umahluko ingabonwa kuphela phantsi iglasi.

Olunye uphawu ebalulekileyo enekhamera isizalo ubukhulu ebonakalayo. Usoloko ubukhulu enkulu emzimbeni ngayo, kokukhona kungcono umlinganiselo umqondiso / ingxolo, ukuze bakwazi ukufumana umfanekiso ezikumgangatho ophezulu, ukuba umbala yendalo. Omunye ongathi inkulu ubungakanani matrix kumanqanba pixels, phezulu umgangatho imifanekiso.
