Lub Koob Yees Duab Module yog dab tsi?

Lub koob yees duab Module, tseem hu ua Camera Compact Module, abbreviated li CCM, muaj plaub yam tseem ceeb: lens, sensor, FPC, thiab DSP. Qhov tseem ceeb ntawm kev txiav txim siab lub koob yees duab yog qhov zoo lossis qhov tsis zoo yog: lens, DSP, thiab sensor.Cov thev naus laus zis tseem ceeb ntawm CCM yog: optical tsim tshuab, aspherical iav ntau lawm technology, optical txheej tshuab.

Lub Koob Yees Duab Module Cheebtsam

1. Lens

Lens yog ib qho cuab yeej uas tuaj yeem tau txais cov teeb liab teeb liab thiab sib txuas cov teeb liab teeb liab hauv lub sensor CMOS / CCD. lens txiav txim siab lub teeb sau tus nqi ntawm lub sensor, nws tag nrho cov nyhuv txheeb ze rau lub lens convex. Optical lens qauv yog: lens chim (Barrel), lens pawg (P / G), lens tiv thaiv txheej (gasket), lim, lens tuav (Holder).

Lub koob yees duab module lens tau muab faib ua lub lens yas (PLASTIC) thiab iav lens (GLASS), lub koob yees duab dav dav muaj ntau lub lo ntsiab muag, feem ntau lub lens rau lub koob yees duab module yog: 1P, 2P, 3P, 1G1P, 1G2P, 2G2P, 4G, thiab lwm yam. .. Qhov ntau ntawm cov lo ntsiab muag, tus nqi ntau dua; Feem ntau, lub iav lo ntsiab muag yuav muaj cov duab zoo dua piv nrog lub lens yas. Txawm li cas los xij, lub iav lens yuav kim dua li lub lens yas.

2. IR CUT(Infrared Filter)

Muaj ntau yam wavelengths ntawm lub teeb nyob rau hauv cov xwm, tib neeg lub qhov muag los txheeb xyuas lub wavelength ntau ntawm lub teeb ntawm 320nm-760nm, ntau tshaj 320nm-760nm lub teeb uas tib neeg lub qhov muag tsis pom; thiab lub koob yees duab imaging Cheebtsam CCD lossis CMOS tuaj yeem pom feem ntau ntawm lub teeb ntawm lub teeb. Vim muaj kev koom tes ntawm ntau yam teeb pom kev zoo, cov xim rov qab los ntawm lub koob yees duab thiab qhov muag liab qab hauv cov xim sib txawv. Xws li cov nroj tsuag ntsuab ua grey, cov duab liab dhau los ua lub teeb liab, dub ua ntshav, thiab lwm yam.. Thaum hmo ntuj vim cov nyhuv lim dej ntawm bimodal lim, kom CCD tsis tuaj yeem siv tag nrho cov teeb pom kev zoo, tsis txhob tsim cov daus. Lub suab nrov tshwm sim thiab nws qhov kev ua haujlwm qis qis yog qhov nyuaj kom txaus siab. Txhawm rau daws qhov teeb meem no, siv IR-CUT ob lub lim dej.

IR-CUT dual lim yog ib txheej ntawm cov ntxaij lim dej ua rau hauv lub koob yees duab lens teeb, thaum lub lens sab nraum lub infrared sensor taw tes los xyuas qhov kev hloov ntawm lub teeb, lub built-in IR-CUT tsis siv neeg hloov lim tuaj yeem ua raws li lub zog. ntawm sab nraud lub teeb thiab ces cia li hloov, kom cov duab mus cuag tau qhov zoo tshaj plaws. Hauv lwm lo lus, cov ntxaij lim dej dual tuaj yeem hloov cov lim dej hauv nruab hnub lossis hmo ntuj, kom cov duab zoo tshaj plaws tuaj yeem tau txais txawm nyob rau nruab hnub lossis hmo ntuj.

3. VCM (Voice Coil Tsav)

koob yees duab moodule- VCM

Lub npe Lub Suab Coil Montor, hluav taws xob hauv lub suab coil lub cev muaj zog, yog hom lub cev muaj zog. Vim tias lub hauv paus ntsiab lus zoo ib yam li tus neeg hais lus, thiaj li hu ua lub suab coil lub cev muaj zog, nrog cov lus teb ntau zaus, cov yam ntxwv siab precision. Nws lub hauv paus ntsiab lus tseem ceeb yog nyob rau hauv ib qho chaw sib nqus mus tas li, los ntawm kev hloov qhov loj ntawm DC tam sim no nyob rau hauv lub cev muaj zog coil los tswj txoj hauj lwm stretching ntawm lub caij nplooj ntoos hlav, thiaj li yuav tsav lub nce thiab nqis zog. Lub koob yees duab compact module dav siv VCM kom paub txog qhov ua haujlwm autofocus, thiab txoj haujlwm ntawm lub lens tuaj yeem hloov kho los ntawm VCM los nthuav tawm cov duab meej.

4. Duab Sensor

Duab sensor yog ib tug semiconductor nti, nws nto muaj tsheej lab mus rau kaum tawm lab tus photodiodes, photodiodes los ntawm lub teeb yuav tsim ib tug nqi hluav taws xob, lub teeb yuav hloov mus rau hauv hluav taws xob signals. Nws txoj haujlwm zoo ib yam li tib neeg lub qhov muag, yog li kev ua haujlwm ntawm sensor yuav cuam tshuam ncaj qha rau kev ua haujlwm ntawm lub koob yees duab.

5. DSP

Digital Signal Processor (DSP) yog microprocessor tshwj xeeb tshaj yog tsim rau kev ua haujlwm ntawm cov teeb liab digital, thiab nws daim ntawv thov tseem ceeb yog lub sijhawm tiag tiag thiab kev siv ceev ceev ntawm ntau yam teeb liab ua cov algorithms.

Kev Ua Haujlwm: Lub hom phiaj tseem ceeb yog txhawm rau txhim kho cov duab digital teeb liab tsis dhau los ntawm cov lej ntawm cov lej nyuaj, thiab xa cov teeb liab ua tiav rau hauv xov tooj ntawm tes, khoos phis tawj thiab lwm yam khoom siv ntawm USB thiab lwm yam cuam tshuam.
