1. General Description
The BF3005 is a highly integrated VGA camera chip which includes CMOS image sensor(CIS),image signal processing function (ISP),TV-encoder. It is fabricated with the world’s most advanced CMos image sensor process to realize ultra-low dark noise, high sensitivity, high dynamic range and very low power imaging system. The sensor consists of a654x583 pixel array which has an optical format of 1/4 inch.lt has integrated noise canceling CDS(Correlated Double Sampling)circuits,analog global gain and separated R/G/B gain controller,auto black level compensationon-chip10-bit ADC,and TV encoder. The on-chip ISPprovides a very smooth AE (Auto Exposure)and accurate AWB (Auto White Balance) control. It provides various data formatssuch as Bayer RGBRGB565YCbCr4:2:2 and CCIR656.
The product is capable of operating at up to 60 frames per second at 54MHz master clock in VGA mode, with complete user control over image quality and data formatting. All required image processing functions, including exposure control, white balance control, color saturation control and so on,are also programmable through the two-wire serial bus
