Isakhiwo nokuthuthuka kwemojuli yekhamera

I. Isakhiwo nokuthuthukiswa kwamamojula wekhamera
Amakhamera asetshenziswe kabanzi emikhiqizweni ehlukahlukene ye-elekthronikhi, ikakhulukazi ukuthuthukiswa okusheshayo kwezimboni ezifana nomakhalekhukhwini namathebulethi, okuye kwabangela 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 enye yezinto ezisetshenziswayo ezijwayelekile zamadivaysi e-elekthronikhi aphathwayo njengamafoni ahlakaniphile namathebulethi. .Amamojula ekhamera asetshenziswa kuzinto zikagesi eziphathwayo azikwazi nje ukuthwebula izithombe, kodwa futhi asize izisetshenziswa zikagesi eziphathwayo ukuthi zibone amakholi wevidiyo asheshayo neminye imisebenzi.Ngomkhuba wokuthuthukisa wokuthi izinto zikagesi eziphathwayo ziba zizacile futhi zibe lula futhi abasebenzisi banezidingo eziphakeme neziphakeme zekhwalithi yokuthwebula yamamojula ekhamera, izidingo eziqine kakhulu zibekwe kusayizi ophelele kanye namandla okuthwebula amamojula wekhamera.Ngamanye amazwi, ukuthuthukiswa kwezinto ze-elekthronikhi eziphathwayo kudinga amamojula ekhamera ukuthi athuthuke futhi aqinise amandla ezithombe ngesisekelo sosayizi oncishisiwe.

Kusukela kusakhiwo sekhamera yeselula, izingxenye ezinhlanu eziyinhloko yilezi: inzwa yesithombe (iguqula amasignali okukhanya abe amasignali kagesi), Ilensi, isithuthuthu sekhoyili yezwi, imojula yekhamera nesihlungi se-infrared.Iketango lemboni yekhamera lingahlukaniswa libe yi-lens, i-coil motor yezwi, isihlungi se-infrared, inzwa ye-CMOS, iphrosesa yesithombe kanye nokupakishwa kwemojula.Imboni inomkhawulo ophezulu wezobuchwepheshe kanye nezinga eliphezulu lokugxila embonini.Imojuli yekhamera ihlanganisa:
1. Ibhodi lesekethe elinamasekhethi nezinto zikagesi;
2. Iphakheji eligoqa ingxenye ye-elekthronikhi, futhi imbobo isethwe kuphakheji;
3. I-photosensitive chip exhunywe kusekethe, ingxenye esemaphethelweni ye-photosensitive chip isongwe yiphakheji, futhi ingxenye ephakathi ye-photosensitive chip ifakwa emgodini;
4. Ilensi exhunywe ngokuqinile endaweni engaphezulu yephakheji;futhi
5. Isihlungi esixhunywe ngokuqondile ngelensi, futhi sihlelwe ngaphezu komgodi futhi ngokuphambene ngokuqondile ne-photosensitive chip.
(I) Inzwa yesithombe se-CMOS: Ukukhiqizwa kwezinzwa zesithombe kudinga ubuchwepheshe obuyinkimbinkimbi nenqubo.Imakethe iphethwe ngabakwaSony (Japan), Samsung (South Korea) kanye neHowe Technology (US), ngesabelo semakethe esingaphezu kuka-60%.
(II) Ilensi yeselula: Ilensi iyingxenye yokubona ekhiqiza izithombe, ngokuvamile ezakhiwa izingcezu eziningi.Isetshenziselwa ukwenza izithombe ku-negative noma esikrinini.Amalensi ahlukaniswe amalensi engilazi namalensi eresin.Uma kuqhathaniswa namalensi e-resin, amalensi engilazi anenkomba enkulu ye-refractive (ezacile ngobude obufanayo bokugxila) kanye nokudluliswa kokukhanya okuphezulu.Ngaphezu kwalokho, ukukhiqizwa kwama-lens engilazi kunzima, izinga lokukhiqiza liphansi, futhi izindleko ziphezulu.Ngakho-ke, ama-lens engilazi asetshenziselwa kakhulu imishini yezithombe eziphezulu, futhi ama-resin lens asetshenziselwa kakhulu imishini yezithombe ezisezingeni eliphansi.
(III) I-Voice coil motor (VCM): I-VCM iwuhlobo lwenjini.Amakhamera omakhalekhukhwini asebenzisa kakhulu i-VCM ukuze afinyelele ukugxila ngokuzenzakalela.Nge-VCM, indawo yelensi ingalungiswa ukuze yethule izithombe ezicacile.
(IV) Imojula yekhamera: Ubuchwepheshe bokupakisha be-CSP kancane kancane sebuyinto evamile
Njengoba imakethe inezidingo eziphakeme neziphakeme zama-smartphones azacile nalula, ukubaluleka kwenqubo yokupakishwa kwemojula yekhamera sekugqame kakhulu.Njengamanje, inqubo yokupakisha yemojuli yekhamera evamile ihlanganisa i-COB ne-CSP.Imikhiqizo enamaphikseli aphansi ipakishwa kakhulu ku-CSP, futhi imikhiqizo enamaphikseli aphezulu ngaphezu kuka-5M ipakishwa kakhulu ku-COB.Ngokuthuthuka okuqhubekayo, ubuchwepheshe bokupakisha be-CSP bungena kancane kancane ku-5M nangaphezulu kwemikhiqizo esezingeni eliphezulu futhi kungenzeka bube yibo ubuchwepheshe bokupakisha ngokuzayo.Iqhutshwa umakhalekhukhwini kanye nezinhlelo zokusebenza zezimoto, izinga lemakethe yamamojula liye landa kancane kancane eminyakeni yamuva.
