Yintoni eyona Angle eyiNtloko yeRay

I-lens chief ray angle yi-engile ephakathi kwe-optical axis kunye ne-lens chief ray. I-lens intloko ye-ray yi-ray edlula kwindawo yokumisa ye-optical system kunye nomgca phakathi kwendawo yokungena yomfundi kunye nendawo yento. Isizathu sobukho be-CRA kwiSensor yoMfanekiso kukuba kukho i-FOV (uMmandla wokujonga) kwi-Mirco Lens kumphezulu we-Inzwa yoMfanekiso, kwaye ixabiso le-CRA lixhomekeke kwixabiso lempazamo elithe tye phakathi kweMicro Lens. yeSensom yoMfanekiso kunye nendawo yesilicon photodiode. Injongo kukudibanisa ngcono i-lens.

I-lens eyintloko ye-engile

Ukukhetha i-CRA ehambelanayo yeLens&ISensor yoMfanekiso kunokuqinisekisa ukubanjwa ngokuchanekileyo kweefotoni kwiifotodiodi ze-silicon, ngaloo ndlela kuncitshiswe i-optical crosstalk.

Kwizinzwa zomfanekiso ezinamaphikseli amancinci, i-angle ye-ray eyintloko ibe yipharamitha ebalulekileyo. Oku kungenxa yokuba ukukhanya kufuneka kudlule kubunzulu bepikseli ukufikelela kwi-silicon photodiode esezantsi kwepikseli, enceda ukwandisa ukukhanya okuya ngqo kwi-photodiode kunye nokunciphisa umthamo wokukhanya okungena kwi-silicon. i-photodiode ye-pixel ekufutshane (Ukudala i-optical crosstalk).

Ngoko ke, xa isivamvo soMfanekiso sikhetha ilens, sinokubuza umenzi weSensom yoMfanekiso & umenzi welensi weCRA igophe lokuthelekisa; ngokuqhelekileyo kucetyiswa ukuba umehluko we-angle ye-CRA phakathi kwe-Inzwa yoMfanekiso kunye ne-lens ilawulwa ngaphakathi kwe-+/-3 degrees, ngokuqinisekileyo, i-Pixel encinci, iphezulu imfuneko.

Iziphumo ze-lens ye-CRA kunye ne-sensor ye-CRA yokungafani:

Iziphumo ezingafaniyo kwi-crosstalk ebangela ukungalingani kombala kuwo wonke umfanekiso, okukhokelela ekunciphiseni umlinganiselo we-signal-to-noise ratio (SNR); njengoko i-CCM ifuna ukwanda kwengeniso yedijithali ukuhlawulela ilahleko yomqondiso kwi-photodiode.

Iziphumo ze-lens ye-CRA kunye ne-sensor ye-CRA yokungafani

Ukuba i-CRA ayihambelani, iya kubangela iingxaki ezinje ngemifanekiso emfiliba, inkungu, umahluko ophantsi, imibala efipheleyo, kunye nobunzulu obuncitshisiweyo bebala.

I-lens ye-CRA incinci kune-Inzwa yoMfanekiso ye-CRA iya kuvelisa i-Colour shading.

Ukuba iSensom yoMfanekiso incinci kune-CRA yelensi, ukufihlwa kweLens kuyakwenzeka.

Ngoko ke kufuneka siqale siqinisekise ukuba Umbala wombala awubonakali, kuba iLens shading ilula ukuyicombulula ngokulungisa iimpazamo kune-Colour shading.

ISensom yoMfanekiso kunye nelensi CRA

Inokubonwa kumzobo ongentla ukuba i-TTL ye-lens nayo isitshixo ekunqumeni i-angle ye-CRA. Okukhona isezantsi i-TTL, kokukhona inkulu i-engile ye-CRA. Ke ngoko, isivamvo somfanekiso esineepikseli ezincinci sikwabaluleke kakhulu kwilensi yeCRA ehambelanayo xa kuyilwa inkqubo yekhamera.

Rhoqo, i-CRA yelensi ayihambelani ncam ne-Inzwa yoMfanekiso ye-CRA ngezizathu ezahlukeneyo. Kuye kwaqatshelwa ngovavanyo ukuba iilensi ze-CRA ezigobileyo ezinomphezulu osicaba (ubuncinci beflip) ziyanyamezela ngakumbi kwiimodyuli zeemodyuli ezahlukeneyo zekhamera kunee-CRA ezigobileyo.

I-CRA yelensi ayihambelani ncam nesivamvo soMfanekiso i-CRA ngezizathu ezahlukeneyo

Le mifanekiso ingezantsi ibonisa imizekelo yee-CRAs ezithe tyaba eziphezulu kunye negophe.

Imizekelo yomphezulu osicaba kunye neeCRA ezigobileyo

Ukuba i-CRA ye-lens ihluke kakhulu kwi-CRA ye-sensor yomfanekiso, umbala wemibala uya kubonakala njengoko kuboniswe kumfanekiso ongezantsi.
