1.Inkcazo ngokubanzi |
I-BF3005 yi-chip yekhamera ye-VGA edityanisiweyo kakhulu equka i-sensor ye-CMOS yomfanekiso (i-CIS), umsebenzi wokulungiswa komfanekiso (ISP), i-encoder ye-TV.Yenziwe ngeyona nkqubo iphambili yehlabathi ye-CMos yokubona ingxolo emnyama esezantsi, ubuntununtunu obuphezulu, uluhlu oluguquguqukayo oluphezulu kunye nenkqubo yokucinga yamandla aphantsi kakhulu.Isivamvo siqulathe i-a654x583 pixel array enefomathi yokubona ye-1/4 intshi.lt ine-CDS edibeneyo yokurhoxisa ingxolo (i-Correlated Double Sampling)iisekethe,inzuzo ye-analog yehlabathi kunye nokwahlulahlula umlawuli we-R/G/B,inqanaba elizenzekelayo lembuyekezo kwi-chip10. -bit ADC, kunye ne-encoder yeTV.I-on-chip ISPibonelela nge-AE egudileyo kakhulu (i-Auto Exposure) kunye nolawulo oluchanekileyo lwe-AWB (i-Auto White Balance).Ibonelela ngeefomathi zedatha ezahlukeneyo njengeBayer RGBRGB565YCbCr4:2:2 kunye neCCIR656.
Imveliso iyakwazi ukusebenza ukuya kuthi ga kwiifreyimu ezingama-60 ngesekhondi kwi-54MHz master clock kwimowudi yeVGA, enolawulo olupheleleyo lomsebenzisi phezu komgangatho womfanekiso kunye nokufomatha idatha.Yonke imisebenzi efunekayo yokusetyenzwa kwemifanekiso, kubandakanywa nolawulo lokuvezwa, ulawulo olumhlophe lokulinganisa, ulawulo lokugcwala kombala njalo njalo, zikwacwangciswa ngebhasi yothotho lweengcingo ezimbini.
2.Iimbonakalo
Ifomathi eqhelekileyo ye-intshi ye-1/4.
60frames/secVGAmode@27MHZ xclk iwotshi.Ingxolo emnyama ephantsi kakhulu kubushushu obuphezulu.
Ukusetyenziswa kwamandla okuphantsi kwe-150mW@60fps(VGAoutput),60uAat amandla ezantsi.
Iifomati zemveliso ezahlukeneyo:YCbCr4:22RGB565,Raw Bayer(652*480), CCIR656(720X576)
Unikezelo lwamandla: 1.5V yedijithali core1.7V ~ 3.5V for/O315V~3.45V for VDD3A.Isibuko seNertical esithe tye.50/60Hzflicker ukucinywa.Ulawulo lwenqanaba oluzenzekelayo olumnyama.
Umsebenzi wokulungiswa kwe-lmage: Ukulungiswa koMthunzi weLens, ukulungiswa kweGamma, ukulungiswa kwe-pixel embi, ukuNxibelela koMbala, i-Low Pass Filter ye-Space Conversion, i-Colour CorrectionEdge Enhancement Ukuvezwa kwe-Auto White BalanceColor Saturation kunye ne-Contrastand Data Format Conversion, i-TV encode output.Umqulu:CSP
