Menene Modul Kamara?

Module Kamara, wanda kuma aka sani da Camera Compact Module, wanda aka gajarta da CCM, ya ƙunshi manyan abubuwa guda huɗu: ruwan tabarau, firikwensin, FPC, da DSP. Abubuwan da ke da mahimmanci don yanke shawarar kamara yana da kyau ko mara kyau sune: ruwan tabarau, DSP, da firikwensin.Mahimman fasahohin CCM sune: fasahar ƙirar ƙira, fasahar samar da madubi na aspherical, fasahar suturar gani.

Abubuwan Modulun Kyamara

1. Lens

Lens na'ura ce da zata iya karɓar sigina na haske da haɗa siginar haske a cikin firikwensin CMOS/CCD. ruwan tabarau yana ƙayyade ƙimar girbin haske na firikwensin, gabaɗayan tasirinsa dangane da ruwan tabarau mai ɗaukar hoto. Tsarin ruwan tabarau na gani shine: ganga ruwan tabarau (Barrel), rukunin ruwan tabarau (P/G), Layer kariya ta ruwan tabarau (gasket), tacewa, mariƙin ruwan tabarau (Mai riƙe).

Ruwan tabarau na kamara ya kasu kashi biyu na ruwan tabarau na filastik (PLASTIC) da gilashin gilashi (GLASS), ruwan tabarau na gabaɗaya ya ƙunshi ruwan tabarau da yawa, yawanci ruwan tabarau na module ɗin kamara shine: 1P, 2P, 3P, 1G1P, 1G2P, 2G2P, 4G, da sauransu. .. Yawan adadin ruwan tabarau, mafi girman farashi; gabaɗaya, ruwan tabarau na gilashi zai sami sakamako mai kyau na hoto idan aka kwatanta da ruwan tabarau na filastik. Koyaya, ruwan tabarau na gilashin zai fi tsada fiye da ruwan tabarau na filastik.

2. IR CUT(Tace Yanke Infrared)

Don magance wannan matsala, amfani da IR-CUT tacewa biyu.

IR-CUT dual filter shine saitin tacewa da aka gina a cikin saitin ruwan tabarau na kamara, lokacin da ruwan tabarau a waje da ma'aunin firikwensin infrared don gano canje-canje a cikin ƙarfin haske, ginin IR-CUT na atomatik mai sauyawa na atomatik zai iya dogara ne akan ƙarfin. na haske na waje sannan kuma ta atomatik canzawa, don haka hoton ya sami sakamako mafi kyau. A wasu kalmomi, masu tacewa biyu na iya canza matattara ta atomatik da rana ko da daddare, ta yadda za a iya samun mafi kyawun tasirin hoto ko da rana ko da dare.

3. VCM (Voice Coil Motor)

yanayin kamara- VCM

Cikakken suna Voice Coil Montor, na'urorin lantarki a cikin injin muryoyin murya, nau'in mota ne. Domin ƙa'idar tana kama da mai magana, wanda ake kira motar murɗa murya, tare da amsawar mitar mai girma, halaye masu inganci. Babban ka'idarsa shine a cikin filin maganadisu na dindindin, ta hanyar canza girman halin yanzu na DC a cikin coil ɗin motar don sarrafa matsayi na shimfidawa na bazara, don fitar da motsi sama da ƙasa. Karamin samfurin kamara yana amfani da VCM ko'ina don gane aikin mai da hankali kan kai, kuma VCM na iya daidaita matsayin ruwan tabarau don gabatar da cikakkun hotuna.

4. Hoton Sensor

Na'urar firikwensin hoto guntu ce ta semiconductor, samansa yana da miliyoyin zuwa dubun dubatar photodiodes, photodiodes ta hanyar haske zai haifar da cajin lantarki, hasken zai canza zuwa siginar lantarki. Ayyukansa yana kama da idon ɗan adam, don haka aikin firikwensin zai shafi aikin kamara kai tsaye.

5. DSP

Mai sarrafa siginar dijital (DSP) microprocessor ne musamman dacewa da ayyukan sarrafa siginar dijital, kuma babban aikace-aikacen sa shine ainihin-lokaci da saurin aiwatar da algorithms sarrafa siginar dijital daban-daban.

Aiki: Babban manufar ita ce inganta siginar siginar hoto na dijital ta hanyar jerin hadaddun algorithms na lissafi, da kuma watsa siginar da aka sarrafa zuwa wayoyin hannu, kwamfutoci da sauran na'urori ta hanyar USB da sauran hanyoyin sadarwa.
