Ubume kunye nophuhliso lwemodyuli yekhamera

I. Ubume kunye nentsingiselo yophuhliso lweemodyuli zekhamera
Iikhamera zisetyenziswe ngokubanzi kwiimveliso ezahlukeneyo ze-elektroniki, ngakumbi uphuhliso olukhawulezayo lwamashishini afana neefowuni eziphathwayo kunye neetafile, eziye zaqhuba ukukhula ngokukhawuleza kweshishini lekhamera.Kwiminyaka yakutshanje, iimodyuli zekhamera ezisetyenziselwa ukufumana imifanekiso ziye zasetyenziswa kakhulu kwii-elektroniki zomntu, iimoto, unyango, njl. .Iimodyuli zekhamera ezisetyenziswa kwizixhobo zombane eziphathwayo azikwazi ukufota kuphela imifanekiso, kodwa zikwanceda izixhobo zombane eziphathwayo ziqonde iifowuni zevidiyo ezikhawulezayo kunye neminye imisebenzi.Ngomkhwa wophuhliso wokuba izixhobo zombane eziphathwayo zibe zincinci kwaye zibe khaphukhaphu kwaye abasebenzisi baneemfuno eziphezulu neziphezulu zomgangatho wokucinga weemodyuli zekhamera, iimfuno ezingqongqo zibekwe kubungakanani obupheleleyo kunye nobuchule bokucinga beemodyuli zekhamera.Ngamanye amazwi, indlela yophuhliso yezixhobo zombane eziphathwayo zifuna iimodyuli zekhamera ukuqhubela phambili nokuphucula kunye nokomeleza amandla okucinga ngesiseko sobungakanani obuncitshisiweyo.

Ukusuka kwisakhiwo sekhamera yefowuni ephathwayo, ezona nxalenye zintlanu ziphambili zezi: inzwa yomfanekiso (iguqula imiqondiso yokukhanya ibe yimiqondiso yombane), iLens, imodyuli yelizwi, imodyuli yekhamera kunye nesihluzi se-infrared.Ikhonkco loshishino lwekhamera lunokwahlulwa lube yi-lens, i-coil motor yelizwi, i-infrared filter, i-CMOS sensor, iprosesa yesithombe kunye nokupakishwa kwemodyuli.Ishishini linomda wobugcisa obuphezulu kunye nenqanaba eliphezulu lokugxila kwishishini.Imodyuli yekhamera ibandakanya:
1. Ibhodi yesekethe eneesekethe kunye namacandelo e-elektroniki;
2. Iphakheji esongela icandelo lombane, kunye ne-cavity ifakwe kwiphakheji;
3. I-photosensitive chip iqhagamshelwe ngombane kwisekethe, inxalenye ephetheyo ye-photosensitive chip isongelwe yiphakheji, kwaye inxalenye ephakathi ye-photosensitive chip ifakwe kwi-cavity;
4. I-lens edibeneyo edibeneyo kwindawo ephezulu yephakheji;kwaye
5. Isihluzi esidityaniswe ngokuthe ngqo kunye ne-lens, kwaye ihlelwe ngaphezu kwecavity kwaye ichasene ngqo ne-photosensitive chip.
(I) I-sensor ye-CMOS yomfanekiso: Ukuveliswa kweenzwa zomfanekiso kufuna iteknoloji enzima kunye nenkqubo.Imarike ilawulwa yi-Sony (eJapan), i-Samsung (eMzantsi Korea) kunye ne-Howe Technology (US), kunye nesabelo semarike esingaphezulu kwe-60%.
(II) I-lens yefowuni yeselula: I-lens yinxalenye ye-optical eyenza imifanekiso, ngokuqhelekileyo iqulunqwe ngamaqhekeza amaninzi.Isetyenziselwa ukwenza imifanekiso kwi-negative okanye kwiscreen.Iilensi zohlulwe zibe ziilensi zeglasi kunye neelensi zeresin.Xa kuthelekiswa neelensi ze-resin, iilensi zeglasi zinesalathiso esikhulu se-refractive (esincinci kubude obugxininisiweyo obufanayo) kunye nokuhanjiswa kokukhanya okuphezulu.Ukongezelela, ukuveliswa kweeglasi zeglasi kunzima, izinga lesivuno liphantsi, kwaye ixabiso liphezulu.Ke ngoko, iilensi zeglasi zisetyenziswa kakhulu kwizixhobo zokufota ezikwisiphelo esiphezulu, kwaye iilensi zeresin zisetyenziswa kakhulu kwizixhobo zokufota ezikwisiphelo esisezantsi.
(III) I-Voice coil motor (VCM): I-VCM luhlobo lwemoto.Iikhamera zefowuni eziphathwayo zisebenzisa ngokubanzi iVCM ukufezekisa ukugxila ngokuzenzekelayo.Nge-VCM, indawo ye-lens inokulungiswa ukuze ibonise imifanekiso ecacileyo.
(IV) Imodyuli yekhamera: Itekhnoloji yokupakisha yeCSP ngokuthe ngcembe ibe yeyona nto iphambili
Njengoko intengiso ineemfuno eziphezulu neziphezulu zee-smartphones ezincinci kunye nezikhaphukhaphu, ukubaluleka kwenkqubo yokupakishwa kwemodyuli yekhamera kuye kwanda kakhulu.Okwangoku, inkqubo yokupakishwa kwemodyuli yekhamera eqhelekileyo ibandakanya iCOB kunye neCSP.Iimveliso ezineepixels ezisezantsi zipakishwe ikakhulu kwi-CSP, kwaye iimveliso ezineepixels eziphezulu ngaphezulu kwe-5M zipakishwe ikakhulu kwi-COB.Ngokuqhubela phambili okuqhubekayo, itekhnoloji yokupakisha ye-CSP ingena ngokuthe ngcembe kwi-5M nangaphezulu kweemveliso eziphezulu kwaye inokwenzeka ukuba ibe yeyona nto iphambili yokupakisha iteknoloji kwixesha elizayo.Iqhutywa yifowuni ephathwayo kunye nokusetyenziswa kweemoto, ubungakanani bemakethi yemodyuli yonyuke kancinci kancinci kwiminyaka yakutshanje.
