Camera furta

macaamiisha Ruush yihiin kamaradaha digital sii kordheysa oo caan ah iyo kamaradaha. Maalin kasta, saarayaasha dunida ee ay soo saaraan daydo cusub, fursado badan oo sawiro. Maanta, qofka caadiga ah waxay noqon kartaa mid adag in la ogaado ee doorashada ee camera ah. Mararka qaarkood soo maray wax iibiya ee dukaanka oo ma awoodo inuu siiyo golaha cad oo uu doorashada. Taasi waa sababta lover ah sawir, iyo xitaa ka sii badan xirfadle waa in ay ogaadaan qaar ka mid ah muuqaalada iyo astaamaha aaladaha casriga ah.

camera furta oo waa mid ka mid ah waxyaabaha ugu muhiimsan ee qalabka sida. Waa qalab shidma leh dareen sare, taas oo ku hubin karnaa beddelidda ee image ah indhaha la saadaaliyey waxaa u gal on siku, inay signal a digital. camera ama camera furta uu saameyn toos ah ku layliga iyo tayada sanamyadii. Bal aynu eegno dhow at waa element this.

Matrix camera digital ka mid ah hannaanka ka mid ah xubno xasaasi ah oo iftiin, kaas oo loogu badalo image ah indhaha galay korontada. pixel kasta waxaa la aasaasay by mid ka mid ah shaxda dhibic of image finalka. By ay qaab-dhismeedka loo qaybin karaa jir buuxa, scan horusocod ah, la column buffered la kacdo warcelin naqdida jir iyo isdhaafsan. Xaaladdan oo kale, furta oo loo qaybin karaa laba nooc oo waaweyn, kuwaas oo hadda laga helo kamaradaha iibiyey.

Noocyada matrices kamaradaha

Muddo dheer aan loo adeegsaday arrimo semiconductors kaabaha xabagta biraha (CMOSka), kuwaas oo daata, iftiinka la helay si demoqaraadiyad ah. Halkan, oo gaabnaa signal lagu samayn karaa meel kasta oo ka, kaliya aad u baahan tahay in la qeexo oo isku xigta iyo column. Sayidka pixel kasta uu kordhiyo signal akhrin. Wax yar ka dib waxaa jiray alaabtii lahaa qalab kharash-xidhay (CCD), kaas oo bilowgii jiray si weyn uga sareynay CMOSka-furta. In nidaamka sida, reading signalka sameeyaa si la mid ah in ay CRT (tube ray cathode), i.e. ka bidix ilaa midig iyo kor ilaa hoos. photodiodes Silicon ahaayeen kiiskan sida xubno photosensitive. In ka sagaashankii hore u soo saaray horumar weyn oo CMOSka-shidma. Sababtoo ah qaababka noocan ah ee noocan ah ee matrices badan ee suurtogalka ah si ay u helaan dareen caadi ah oo tayo leh image sare oo keliya at matrices miisaanka badan caadi ahaan loo isticmaalo in kamaradaha xirfad leh cabbir ballaaran. Haddii aan ka hadlo daydo hiwaayadda la awoodi karo, waxaa fiican inaad doorato kuwa la qalabeeyey CCD shax. Shirkadaha sida kaamirooyinka Canon iyo Nikon soo saaro daydo la modified CMOSka-furta, waa nooc ka mid ah qorshaha kala guurka ah.

camera Matrix ayaa dabeecad u muhiim ah sida xalinta khilaafka. Under ee xalinta loola jeedaa tirada xubno xasaasi ah in shax, kuwaasoo mid walba uu helo iftiinka iyo waxay badasha gelin gaar ah lacag koronto. Waxaa muhiim ah in la fahmo in waxa macno lahayn in ay eryan tirada pixels sida tayada images daabacan waa shiidaa isku mid ah, iyo faraqa u arki karo kaliya wax ka yar weyneyso ah.

dabeecad kale oo muhiim ah taas oo uu leeyahay camera shax waa ay size jirka. More inta badan size waxa ay leedahay badan oo jirka ah, si fiican saamiga signal / qaylada, in awood ay u helaan image ah oo tayo sare, isagoo midab dabiici ah. Mid ka mid ah dhihi karaa in ay ka sii weyn size ee maxalka furta oo at tiro ka mid ah pixels, sare ee tayada images.
