1.Kufotokozera Kwambiri |
BF3005 ndi chipangizo chophatikizika kwambiri cha VGA cha kamera chomwe chimaphatikizapo sensa ya zithunzi za CMOS (CIS), ntchito yopangira ma siginoloji (ISP), encoder ya TV.Amapangidwa ndi makina apamwamba kwambiri padziko lonse lapansi a CMos kuti azindikire phokoso lakuda kwambiri, kukhudzika kwakukulu, kusinthasintha kwakukulu komanso makina oyerekeza amphamvu kwambiri.Sensayi imakhala ndi ma pixel a654x583 omwe ali ndi mawonekedwe owoneka a 1/4 inch.lt ali ndi ma CDS (Correlated Double Sampling) omwe amaletsa phokoso, kupindula kwapadziko lonse ndi kupatukana kwa R/G/B chowongolera, auto black level compensationon-chip10 -bit ADC, ndi encoder ya TV.The on-chip ISP imapereka kuwongolera kosalala kwa AE (Auto Exposure) komanso kolondola kwa AWB (Auto White Balance).Imakhala ndi mitundu yosiyanasiyana ya data monga Bayer RGBRGB565YCbCr4:2:2 ndi CCIR656. Chogulitsacho chimatha kugwira ntchito mpaka mafelemu 60 pa sekondi imodzi pa wotchi yayikulu ya 54MHz mumayendedwe a VGA, ndikuwongolera kwathunthu kwazithunzi ndi masanjidwe a data.Ntchito zonse zofunika kukonza zithunzi, kuphatikiza kuwongolera kuwonetseredwa, kuwongolera koyera, kuwongolera machulukitsidwe amtundu ndi zina zotero, zimakonzedwanso kudzera pabasi yamawaya awiri. |
