Xagalka iftiinka madaxa muraayadda waa xagasha u dhaxaysa dhidibka indhaha iyo iftiinka madaxa muraayadda. Muraayadda madaxa muraayadda waa shucaaca ka gudba joogsiga daloolka ee nidaamka indhaha iyo xariiqda u dhaxaysa bartamaha ardayga soo galaya iyo barta shayga. Sababta jiritaanka CRA ee Muraayadda Sawirka ayaa ah inuu jiro FOV (Field of view) oo ku yaal Muraayadda Mirco oo ku taal dusha sare ee Muraayadda Sawirka, qiimaha CRA-na wuxuu ku xiran yahay qiimaha khaladka toosan ee u dhexeeya Muraayadda Micro ee Muraayadda Sawirka iyo booska Muraayadda Silicon. Ujeedadu waa in si wanaagsan loogu waafajiyo muraayadda.
Xagalka iftiinka madaxa muraayadda
Doorashada CRA isku mid ah oo ah Lens&Image Sensor waxay hubin kartaa qabashada saxda ah ee fotonada loo geliyo silicon photodiodes, taasoo yareynaysa isku-xidhka indhaha.
Dareemayaasha sawirka leh pixels yar yar, xagasha ray-ga ugu weyn waxay noqotay halbeeg muhiim ah. Tani waa sababta oo ah iftiinku waa inuu dhex maraa qoto dheer ee pixel-ka si uu u gaaro photodiode-ka silicon ee hoose ee pixel-ka, kaas oo ka caawiya kordhinta cadadka iftiinka ee gala photodiode-ka isla markaana yareeya cadadka iftiinka ee gala photodiode-ka silicon ee pixel-ka ku xiga (Abuuritaanka isgoysyada indhaha).
Sidaa darteed, marka dareemaha Sawirku doorto muraayad, waxay weydiisan kartaa soo saaraha Sawirka Sensor & soo saaraha muraayadaha inay helaan qalooc CRA ah si ay isugu ekaadaan; guud ahaan waxaa lagu talinayaa in farqiga xagasha CRA ee u dhexeeya Sawirka Sensor iyo muraayadda lagu xakameeyo +/-3 darajo, dabcan, haddii Pixel-ka yar yahay, ayaa baahidu sii kordheysaa.
Saamaynta isku dheelitir la'aanta muraayadda CRA iyo dareemayaasha CRA:
Is-waafajin la'aantu waxay keentaa is-weydaarsi taasoo keenta isku dheelitir la'aan midabka sawirka oo dhan, taasoo keenta hoos u dhac ku yimaada saamiga calaamadda-ilaa-sawaxanka (SNR); maadaama CCM ay u baahan tahay koror faa'iido dijitaal ah si loo magdhabo khasaaraha calaamadda ee photodiode-ka.
Saamaynta isku dheelitir la'aanta muraayadda CRA iyo dareemayaasha CRA
Haddii CRA-du aysan u dhigmin, waxay sababi doontaa dhibaatooyin sida sawirro aan caddayn, ceeryaamo, isbarbardhig hoose, midabyo libdhay, iyo qoto dheer oo duurka ah oo yaraada.
Muraayadda CRA way ka yar tahay tan Sawirka Sensor CRA ay soo saari doonto midabka hooska.
Haddii Dareemaha Sawirka uu ka yar yahay muraayadda CRA, hooska muraayadda ayaa dhici doona.
Markaa marka hore waa inaan hubinnaa in midabka midabku uusan muuqan, sababtoo ah midabka muraayadda ayaa si fudud loogu xallin karaa khaladaadka marka loo eego midabka.
Dareemaha Sawirka iyo Muraayadaha CRA
Waxaa laga arki karaa sawirka kore in TTL-ka muraayadda uu sidoo kale yahay furaha lagu go'aaminayo xagasha CRA. Inta TTL-ku hoos u dhaco, ayaa xagasha CRA-du sii weynaanaysaa. Sidaa darteed, dareemaha sawirka leh pixels-ka yaryar ayaa sidoo kale aad muhiim ugu ah isbarbardhigga muraayadda CRA marka la naqshadaynayo nidaamka kamaradda.
Badanaa, muraayadda CRA si sax ah uma la mid noqoto dareemaha sawirka CRA sababo kala duwan awgood. Waxaa si tijaabo ah loo arkay in qaloocyada muraayadda CRA ee leh dusha sare ee fidsan (ugu yaraan rogrogmada) ay u dulqaadanayaan kala duwanaanshaha isu-imaatinka module-ka kamarada marka loo eego CRA-yada qaloocan.
Muraayadda CRA si sax ah uma eka dareemayaasha sawirka CRA sababo kala duwan awgood
Sawirrada hoose waxay muujinayaan tusaalooyin CRA-yada dusha sare ee fidsan iyo kuwa qaloocan.
Tusaalooyinka CRA-yada dusha sare ee fidsan iyo kuwa qaloocan
Haddii CRA-ga muraayadda uu aad uga duwan yahay CRA-ga dareemaha sawirka, midabka la soo bandhigay ayaa u muuqan doona sida ka muuqata sawirka hoose.
Midabka jilayaashu way muuqdaan
