1.Whakaahuatanga Whanui |
Ko te BF3005 he maramara kamera VGA tino whakauru kei roto ko te CMOS image sensor (CIS), te mahi tukatuka tohu tohu (ISP), TV-encoder.He mea hanga ki te tukanga puoro whakaahua CMos tino matatau o te ao ki te mohio ki te haruru pouri tino iti, te tairongo teitei, te awhe hihiri teitei me te punaha atahanga hiko iti rawa.Kei roto i te pūoko he huinga pika a654x583 he ahua whatu o te 1/4 inihi.lt kua whakaurua te haruru whakakore CDS(Tauira Whakatauira Tauira) iahiko, te taonga o te ao tairitenga me te kaiwhakahaere whiwhinga R/G/B wehea, kapeneheihana taumata pango aunoa-chip10 -bit ADC, me te encoder TV.Ko te ISP i runga i te maramara he whakarato i te AE (Auto Exposure) me te mana tika AWB (Auto White Balance).He maha nga whakatakotoranga raraunga penei i te Bayer RGBRGB565YCbCr4:2:2 me CCIR656. Ka taea e te hua te mahi ki runga ki te 60 papa mo ia hekona i te karaka matua 54MHz i roto i te aratau VGA, me te mana katoa o te kaiwhakamahi ki te kounga o te ahua me te whakatakotoranga raraunga.Ko nga mahi tukatuka whakaahua katoa e hiahiatia ana, tae atu ki te mana whakamohiotanga, te mana toenga ma, te mana o te tae tae me etahi atu, ka taea te whakarite ma te pahi rangatū waea-rua. |
