Taw qhia
Puas tau sim ua qhov ze- yees duab thiab pom nws pom qhov muag plooj vim lub koob yees duab tsom rau tom qab hloov? Qhov ntawd yog ib qho teeb meem tsom. Autofocus daws nws. Hauv cov koob yees duab modules, autofocus tau hloov kho lub lens txoj hauj lwm kom cov ntsiab lus ntse, tsis muaj kev pab. Cov yam ntxwv no yog qhov tseem ceeb rau ntau daim ntawv thov-los ntawm kev yees duab smartphone mus rau kev nyab xeeb tsheb thiab kev tshuaj xyuas kev lag luam. Ntawm Kev Ntseeg, peb tau tsim lub koob yees duab modules rau ntau tshaj 30 xyoo, thiab autofocus yog qhov kev xaiv tseem ceeb. Kab lus no piav qhia tias autofocus yog dab tsi, nws ua haujlwm li cas, thiab qhov twg nws siv.
Autofocus yog dab tsi?
Autofocus yog lub tshuab uas txav lub lens hauv lub koob yees duab module kom coj cov ntsiab lus mus rau qhov ntse ntse. Lub koob yees duab soj ntsuam cov duab hauv lub sijhawm tiag tiag thiab kho lub lens kom txog thaum cov duab ntse. Ibauto focus camera moduletshem tawm qhov xav tau ntawm phau ntawv tsom, ua rau nws zoo tagnrho thaum qhov kev ncua deb ntawm qhov kev kawm hloov ntau zaus.
Yuav ua li cas Autofocus ua haujlwm
1. Kev kuaj pom qhov sib txawv
Lub koob yees duab txav lub lens rov qab thiab tawm me ntsis thaum ntsuas cov duab sib piv. Txoj hauj lwm nrog qhov sib txawv siab tshaj plaws yog nyob rau hauv tsom. Muaj tseeb tab sis tuaj yeem ua qeeb, tshwj xeeb tshaj yog nyob rau lub teeb qis. Feem ntau hauv webcams thiab cov koob yees duab kev lag luam yooj yim.
2. Phase Detection (PDAF)
Tshwj xeeb sensor pixels faib lub teeb tuaj rau hauv ob halves. Lub koob yees duab ntsuas cov theem sib txawv los txiav txim seb yuav txav lub lens mus deb npaum li cas. Ntau npaum li qhov sib piv kom pom. Siv hauv smartphones thiab automotive koob yees duab.
3. Hybrid Autofocus
Muab cov kev tshawb nrhiav theem rau kev ceev thiab qhov sib piv rau qhov raug. Ntaulub koob yees duab hd moduletsim siv hybrid autofocus kom ceev, meej tsom.
4. Laser lossis Sijhawm - ntawm - Davhlau (ToF)
Lub koob yees duab tso lub laser lossis IR mem tes thiab ntsuas lub sijhawm rov qab los. Muab kev ncua deb, tso cai rau lub lens txav ncaj qha mus rau txoj haujlwm raug. Ua haujlwm zoo nyob rau hauv lub teeb qis.
Hom Autofocus Mechanisms
- Lub Suab Coil Tsav (VCM):Feem ntau. Ib co coil thiab hlau nplaum txav lub lens. Compact, tus nqi qis, txhim khu kev qha. Siv hauv smartphones, webcams, thiab ntau yamautomotive koob yees duab moduletsim.
- Stepper Tsav:Ntau meej tab sis loj dua thiab qeeb dua. Siv nyob rau hauv industrial thiab soj ntsuam lub koob yees duab.
- Piezoelectric Actuator:Ceev heev, meej, ntsiag to. Siv nyob rau hauv high- lo ntsiab muag kawg.
- Liquid Lens:Tsis muaj qhov txav txav; hluav taws xob tswj cov kua dej hloov tsom. Ceev, ruaj. Tawm hauvautomotive soj ntsuam lub koob yees duabdaim ntawv thov.
Vim li cas Autofocus tseem ceeb
Automotive
Feem ntau ADAS lub koob yees duab siv lub ntsej muag ruaj khov nrog qhov tob ntawm qhov loj. Tab sis rau kev saib xyuas tus neeg tsav tsheb (tshaj tus tsav tsheb lub ntsej muag) lossis lub koob yees duab sab hauv, autofocus ua kom cov ntsiab lus ntse thaum tus tsav tsheb txav. Rau ibautomotive soj ntsuam lub koob yees duabsiv nyob rau hauv cov chaw pabcuam, autofocus cia cov kws kho tsheb tshawb xyuas qhov chaw ntawm qhov sib txawv yam tsis tau rov ua dua manually.
Kev kho mob Endoscopy
Feem ntau cov kws kho mob endoscopes siv qhov ua kom pom tseeb vim tias qhov ua haujlwm nyob deb tau paub thiab autofocus mechanisms loj dhau. Qee qhov phais microscopes siv autofocus.
Kev soj ntsuam kev lag luam
Hauv factories, ibauto focus camera moduleyog qhov tseem ceeb rau kev tshuaj xyuas qhov chaw ntawm qhov sib txawv ntawm ib txoj kab txav. Nws txuag lub sijhawm thiab ua kom zoo ib yam.
Consumer Electronics
Smartphones, webcams, thiab lub koob yees duab ua haujlwm cia siab rau autofocus rau cov duab thiab cov yeeb yaj kiab. Azoo tshaj lub koob yees duab modulerau cov neeg siv khoom siv yuav luag ib txwm suav nrog ceev, raug autofocus.
Cov txiaj ntsig ntawm Autofocus
- Yooj yim: tsis muaj kev hloov kho.
- Ceev: refocuss instantly thaum lub ntsiab lus txav.
- Qhov tseeb: cov tshuab niaj hnub no yog qhov tseeb heev.
- Versatility: ua haujlwm nyob rau ntau qhov kev ncua deb.
Kev lag luam -Offs
- Loj:Autofocus mechanisms ntxiv thickness. Tsau tsom modules me dua.
- Tus nqi:Autofocus nce kev tivthaiv thiab sib dhos nqi.
- Lub zog:Tsiv lub lens siv lub zog.
- Kev ntseeg tau:Cov khoom txav tuaj yeem hnav, txawm tias niaj hnub VCM yog qhov ruaj khov.
- Tsawg- lub teeb nrawm:Kev kuaj pom qhov sib txawv tuaj yeem tua hauv qhov tsaus ntuj.
Thaum Kho kom pom tseeb zoo dua
Tsau tsom iav lo ntsiab muag tau teeb tsa kom txhua yam los ntawm ob peb centimeters mus rau infinity yog qhov ntse ntse. Feem ntau hauv:
- Automotive koob yees duab modulerau rearview los yog ib puag ncig- saib (loj qhov tob ntawm qhov xav tau)
- Cov koob yees duab tshuaj xyuas yeeb nkab (tsawg ua haujlwm nrug)
- Endoscopy (txoj kab me me tiv thaiv qhov txav mus los)
- Tsawg-cov neeg siv koob yees duab raug nqi
