Kapangidwe ndi kakulidwe ka module ya kamera

I. Kapangidwe ndi kakulidwe ka ma module a kamera
Makamera akhala akugwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zamagetsi, makamaka kukula kwachangu kwa mafakitale monga mafoni a m'manja ndi mapiritsi, zomwe zachititsa kuti makampani a kamera ayambe kukula mofulumira.M'zaka zaposachedwa, ma module a kamera omwe amagwiritsidwa ntchito kupeza zithunzi akhala akugwiritsidwa ntchito kwambiri pamagetsi aumwini, magalimoto, azachipatala, ndi zina zotero. .Ma module a kamera omwe amagwiritsidwa ntchito pazida zam'manja zamagetsi sangathe kujambula zithunzi zokha, komanso amathandizira zida zamagetsi zonyamulika kuzindikira kuyimba kwamavidiyo pompopompo ndi ntchito zina.Ndi kachitidwe kachitukuko komwe zida zamagetsi zam'manja zimakhala zocheperako komanso zopepuka ndipo ogwiritsa ntchito amakhala ndi zofunikira zapamwamba komanso zapamwamba zamtundu wazithunzi zama module a kamera, zofunikira zolimba zimayikidwa pakukula konse ndi kuthekera kwazithunzi zama module a kamera.Mwa kuyankhula kwina, chitukuko cha zipangizo zamagetsi zonyamula katundu zimafuna ma modules a kamera kuti apititse patsogolo ndikulimbitsa luso la kujambula pamaziko a kukula kochepa.

Kuchokera pamapangidwe a kamera ya foni yam'manja, zigawo zisanu zazikuluzikulu ndi izi: sensa ya chithunzi (imasintha ma siginecha opepuka kukhala ma siginecha amagetsi), Lens, mota ya coil ya mawu, module ya kamera ndi fyuluta ya infrared.Makina opanga makamera amatha kugawidwa kukhala ma lens, mota ya coil ya mawu, fyuluta ya infrared, sensa ya CMOS, purosesa ya zithunzi ndi ma module.Makampaniwa ali ndi luso lapamwamba kwambiri komanso kuchuluka kwamakampani.Module ya kamera imaphatikizapo:
1. Gulu lozungulira lomwe lili ndi mabwalo ndi zida zamagetsi;
2. Phukusi lomwe limakutira chigawo chamagetsi, ndipo chibowo chimayikidwa mu phukusi;
3. Chip cha photosensitive cholumikizidwa ndi magetsi ku dera, mbali ya m'mphepete mwa chip photosensitive imakutidwa ndi phukusi, ndipo gawo lapakati la photosensitive chip limayikidwa pabowo;
4. Lens yolumikizidwa mokhazikika pamwamba pa phukusi;ndi
5. Fyuluta yolumikizidwa mwachindunji ndi mandala, ndikukonzedwa pamwamba pa patsekeke ndi molunjika motsutsana ndi chipangizo cha photosensitive.
(I) Sensa yazithunzi za CMOS: Kupanga kwa masensa azithunzi kumafuna ukadaulo wovuta komanso njira.Msikawu wakhala ukulamulidwa ndi Sony (Japan), Samsung (South Korea) ndi Howe Technology (US), ndi gawo la msika la 60%.
(II) Lens ya foni yam'manja: Diso ndi chinthu chowoneka bwino chomwe chimapanga zithunzi, zomwe nthawi zambiri zimakhala ndi zidutswa zingapo.Amagwiritsidwa ntchito kupanga zithunzi pazithunzi kapena skrini.Magalasi amagawidwa kukhala magalasi agalasi ndi ma lens a resin.Poyerekeza ndi ma lens a utomoni, magalasi agalasi amakhala ndi index yayikulu yowunikira (yoonda pamtunda womwewo) komanso ma transmittance apamwamba.Kuonjezera apo, kupanga magalasi a galasi ndi kovuta, zokolola zimakhala zochepa, ndipo mtengo wake ndi wapamwamba.Chifukwa chake, magalasi agalasi amagwiritsidwa ntchito kwambiri pazida zazithunzi zapamwamba, ndipo magalasi a resin amagwiritsidwa ntchito kwambiri pazida zotsika.
(III) Voice coil motor (VCM): VCM ndi mtundu wa mota.Makamera amafoni am'manja amagwiritsa ntchito VCM kwambiri kuti akwaniritse kuyang'ana kokha.Kupyolera mu VCM, malo a lens akhoza kusinthidwa kuti apereke zithunzi zomveka bwino.
(IV) Kamera gawo: CSP ma CD luso pang'onopang'ono wakhala waukulu
Popeza msika uli ndi zofunikira zapamwamba komanso zapamwamba zama foni am'manja ocheperako komanso opepuka, kufunikira kwa njira yopangira ma module a kamera kwakula kwambiri.Pakadali pano, njira yayikulu yopangira ma module a kamera ikuphatikiza COB ndi CSP.Zogulitsa zokhala ndi ma pixel otsika zimayikidwa mu CSP, ndipo zokhala ndi ma pixel okwera pamwamba pa 5M zimayikidwa makamaka mu COB.Ndi kupita patsogolo kosalekeza, ukadaulo wophatikizira wa CSP ukulowa pang'onopang'ono mu 5M ndi pamwamba pa zinthu zapamwamba kwambiri ndipo mwina udzakhala wotsogola waukadaulo wazolongedza mtsogolo.Moyendetsedwa ndi mafoni a m'manja ndi magalimoto, kukula kwa msika wa module wakula pang'onopang'ono m'zaka zaposachedwa.
