Lub hauv paus ntsiab lus ntawm USB lub koob yees duab yog los hloov lub teeb liab teeb lub teeb rau hauv cov duab cov ntaub ntawv teeb liab. Yog li ntawd, qhov nyuaj ib puag ncig xws li lub teeb muaj zog, backlight thiab lub teeb tsis muaj zog yuav tam sim ntawd txhim kho cov duab zoo ntawm USB lub koob yees duab.
Cov duab zoo ntawm USB lub koob yees duab yuav tam sim ntawd cuam tshuam qhov tshwm sim tiag tiag thiab kev xav ntawm lub ntsej muag paub thiab pom lub ntsej muag. Yog li ntawd, thaum lub chaw tsim khoom siv lub davhlau ya nyob twg xaiv USB lub koob yees duab qauv, nws yuav tsum tau them sai sai rau qhov tseem ceeb imaging Cheebtsam thiab lub ntsiab tsis tseem ceeb ntawm USB lub koob yees duab, thiaj li yuav xyuas kom meej tias cov duab zoo yav tas los sau tau raws li qhov yuav tsum tau ntawm lub davhlau ya nyob twg cov khoom tsim.
Ntawm peb qhov tseem ceeb ntawm USB lub koob yees duab module: lens, duab sensor thiab DSP duab, lub lens yog lub luag haujlwm rau kev ntes cov khoom thiab tsom cov duab ntes ntawm cov duab sensor. Nws cov kev tsis tseem ceeb suav nrog lub kaum sab xis, focal ntev, CRA, distortion, glare, thiab lwm yam. USB lub koob yees duab module feem ntau siv lub lens ruaj khov nrog ceev ceev ceev, ruaj khov duab zoo thiab raug ntsuas.
Rau cov duab sensor uas converts optical signals mus rau analog teeb liab rau cov zis, nws cov ntsiab lus tsis muaj xws li sensor loj, tsim nyog lub ntsiab lus, specifications, thiab lwm yam. nws yog xav kom pom zoo tias CMOS sensors nrog cov yam ntxwv ntawm kev ua hauj lwm ceev, me me poob, ceev ceev, tsis tshua muaj nqi, thiab lwm yam. Tom qab ntawd, cov xim duab cov ntaub ntawv teeb liab raug xa mus rau DSP duab CPU ntawm lub davhlau ya nyob twg ntaus ntawv tom qab kev txhim kho. Qhov siab -DSP zoo tuaj yeem txhim kho qhov kev sib xyaw ua ke ntawm IC qhov dav ntawm ntau dua 30%.
