Isakhiwo nokuthuthuka okuthambekele kukho kwamamojula wekhamera

Amakhameraziye zasetshenziswa kabanzi emikhiqizweni ehlukahlukene ye-elekthronikhi, ikakhulukazi ukuthuthukiswa okusheshayo kwezimboni ezifana nomakhalekhukhwini namathebulethi, okuye kwaqhuba ukukhula okusheshayo kwemboni yamakhamera.Eminyakeni yamuva nje, amamojula ekhamera asetshenziselwa ukuthola izithombe asevame ukusetshenziswa kakhulu ezintweni zikagesi zomuntu siqu, ezezimoto, ezokwelashwa, njll., isibonelo, amamojula ekhamera abe indinganiso yezinto eziphathwayo zikagesi ezifana namafoni ahlakaniphile namathebulethi amakhompyutha.Enye yezinsiza.Amamojula ekhamera asetshenziswa ezintweni zikagesi eziphathwayo awakwazi nje ukuthwebula izithombe, kodwa futhi asize izisetshenziswa zikagesi eziphathwayo ukuthi zibone amakholi wevidiyo asheshayo neminye imisebenzi.Njengoba ukuthuthukiswa kwezinto zikagesi eziphathwayo ziba mncane futhi zibelula futhi abasebenzisi banezidingo eziphezulu neziphakeme zekhwalithi yokuthwebula yamamojula ekhamera, izidingo eziqinile zibekwe phambili kuwo wonke usayizi wemojuli yekhamera namandla okuthwebula wemojuli yekhamera.Ngamanye amazwi, ukuthuthukiswa kwezinto ze-elekthronikhi eziphathwayo kudinga amamojula ekhamera ukuthi athuthuke futhi aqinise amandla ezithombe ngesisekelo sosayizi oncishisiwe.
Ngokombono wesakhiwo sekhamera kamakhalekhukhwini, izingxenye ezinhlanu eziyinhloko yilezi: Inzwa yesithombe (eguqula amasignali okukhanya abe amasignali kagesi), Ilensi, injini yekhoyili yezwi, imojula yekhamera nesihlungi se-infrared.Uchungechunge lwemboni yekhamera lungahlukaniswa ikakhulukazi izingxenye eziningana: ilensi, injini yekhoyili yezwi, isihlungi se-infrared, inzwa ye-CMOS, iphrosesa yesithombe kanye nokupakishwa kwemojula.Umkhawulo wobuchwepheshe bemboni uphezulu futhi ukugxilwa kwemboni kuphezulu.Imojuli yekhamera ihlanganisa:

1. Ibhodi lesekethe elinamasekhethi nezinto zikagesi;

2. Umzimba wephakeji osonga ingxenye ye-elekthronikhi, kanye nesikhala esisethwe emzimbeni wephakeji;

3. I-chip ye-photosensitive ixhunywe ngogesi kumjikelezo, ingxenye esemaphethelweni ye-chip ye-photosensitive isongwe yiphakheji, futhi ingxenye ephakathi ye-photosensitive chip ifakwe emgodini;

4. Ilensi ixhunywe ngokuqinile endaweni engaphezulu yephakeji yomzimba;

5. Isihlungi sixhunywe ngokuqondile nelensi, futhi sihlelwa ngaphezu komgodi futhi ngokuphambene ngokuqondile ne-photosensitive chip.

(1) Inzwa yesithombe se-CMOS: Ukukhiqizwa kwezinzwa zesithombe kudinga ubuchwepheshe obuyinkimbinkimbi nokucubungula ubuchwepheshe.Imakethe kade iphethwe ngabakwaSony (Japan), Samsung (South Korea) kanye neHowe Technology (US), enesabelo semakethe esingaphezu kuka-60%.

(2) Ilensi yeselula: Ilensi iyingxenye yokubona ekhiqiza isithombe, ngokuvamile esakhiwe ngamalensi amaningi, asetshenziselwa ukwakha isithombe efilimini noma esikrinini.Amalensi ahlukaniswe amalensi engilazi namalensi eresin.Uma kuqhathaniswa namalensi e-resin, amalensi engilazi anenkomba enkulu ye-refractive (ezacile ngobude obufanayo bokugxila) kanye nokudlulisa ukukhanya okuphezulu.Ngaphezu kwalokho, ukukhiqizwa kwama-glass lens kunzima, isivuno siphansi, futhi izindleko ziphezulu.Ngakho-ke, ama-lens engilazi asetshenziselwa kakhulu imishini yezithombe eziphezulu, futhi ama-resin lens asetshenziselwa kakhulu imishini yezithombe ezisezingeni eliphansi.

(3) I-Voice Coil Motor (VCM): I-Voice Coil Motor (I-Voice Coil Motor) i-electronics iwuhlobo lwemoto.Amakhamera omakhalekhukhwini asebenzisa kakhulu i-VCM ukuze afinyelele ukusebenza kwe-auto-focus, lapho indawo yelensi ingalungiswa ukuze yethule izithombe ezicacile.

(4) Imojula yekhamera: Ubuchwepheshe bokupakisha be-CSP sebuyinto evamile

Njengoba imakethe idinga ama-smartphones andayo futhi alula, ukubaluleka kweikhameraInqubo yokupakisha yamamojula isivele igqama kakhulu.Njengamanje, inqubo yokupakisha yemojuli yekhamera evamile ihlanganisa i-COB ne-CSP.Njengamanje, imikhiqizo enamaphikseli aphansi ifakwe ikakhulukazi ku-CSP, futhi imikhiqizo enamaphikseli aphezulu ngaphezu kuka-5M ifakwe ikakhulukazi ku-COB.Ngokuqhubeka okuqhubekayo kobuchwepheshe bokupakisha be-CSP, ubuchwepheshe bokupakisha be-CSP bungena kancane kancane emakethe ye-5M nangaphezulu kwemikhiqizo esezingeni eliphezulu, futhi ubuchwepheshe bokupakisha be-CSP kungenzeka bube yinkambo yobuchwepheshe bokupakisha esikhathini esizayo.Iqhutshwa umakhalekhukhwini kanye nezicelo zezimoto, imakethe yamamojula ikhule unyaka nonyaka eminyakeni yamuva.
