I-BF3005 iyi-chip yekhamera ye-VGA edidiyelwe kakhulu ehlanganisa inzwa yesithombe ye-CMOS(CIS),umsebenzi wokucubungula isignali yesithombe (ISP),isishumeki se-TV.Yakhiwe ngenqubo yenzwa yesithombe ethuthuke kakhulu ye-CMos ukuze kuzwakale umsindo omnyama ophansi kakhulu, ukuzwela okuphezulu, ububanzi obuguquguqukayo obuphezulu kanye nesistimu yokucabanga enamandla aphansi kakhulu.Inzwa iqukethe amaphikseli angamalungu afanayo angu-a654x583 anefomethi yokubona engu-1/4 inch.lt ineziyingi zokukhansela umsindo ezihlanganisiwe ze-CDS(Correlated Double Sampling),inzuzo yomhlaba wonke ye-analog nesilawuli senzuzo esihlukanisiwe se-R/G/B,isinxephezelo sezinga elizenzakalelayo leleveli ku-chip10. -bit ADC, kanye nesishumeki se-TV.I-ISP eku-chip inikeza i-AE ebushelelezi (Auto Exposure) kanye nesilawuli esinembile se-AWB (Ibhalansi Emhlophe Ezenzakalelayo).Ihlinzeka ngamafomethi edatha ahlukahlukene njenge-Bayer RGBRGB565YCbCr4:2:2 kanye ne-CCIR656. Umkhiqizo uyakwazi ukusebenza kufika kumafreyimu angama-60 ngomzuzwana ewashi eliyinhloko elingu-54MHz kumodi ye-VGA, nokulawula okuphelele komsebenzisi phezu kwekhwalithi yesithombe nokufomethwa kwedatha.Yonke imisebenzi edingekayo yokucubungula izithombe, okuhlanganisa nokulawula ukuchayeka, ukulawula ibhalansi emhlophe, ukulawula ukugcwala kombala nokunye, nakho kuyahleleka ngebhasi le-serial elinezintambo ezimbili. |

Ifomethi ye-optical evamile engu-1/4 intshi. 60frames/secVGAmode@27MHZ xclk clock.Umsindo omnyama ophansi kakhulu ezingeni lokushisa eliphezulu. Ukusetshenziswa kwamandla okuphansi kakhulu kwe-150mW@60fps(VGAoutput), amandla aphansi angama-60uAat. Amafomethi okukhiphayo ahlukahlukene:YCbCr4:22RGB565,Raw Bayer(652*480), CCIR656(720X576) Ukunikezwa kwamandla:1.5V kwe-digital core1.7V~3.5V ye/O315V~3.45V ye-VDD3A.Isibuko esivundlile se-Nertical. ukukhansela okungu-50/60Hzflicker.Ukulawula okuzenzakalelayo kwezinga elimnyama. Umsebenzi wokucubungula i-lmage: Ukulungiswa Kokufihla Ukukhanya Kwelensi, Ukulungiswa Kwe-Gamma, Ukulungiswa Kwephikseli Engalungile, Ukuhumusha Kombala, Ukuguqulwa Kombala Wesihlungi Se-Low Pass, I-Color CorrectionEdge Enhancement Ukuvezwa Okuzenzakalelayo Ukugcwaliswa Kwebhalansi Kombala Okumhlophe Okuzenzakalelayo kanye Nokuguqulwa Kwefomethi Yedatha Ephikisanayo, ukuphuma kwekhodi ye-TV.Iphakheji:CSP |
