BYD Microelectronics Co., Ltd.
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 a
654x583 pixel array which has an optical format of 1/4 inch. It has integrated noise canceling
CDS (Correlated Double Sampling) circuits, analog global gain and separated R/G/B gain
controller, auto black level compensation, on-chip 10-bit ADC, and TV encoder. The on-chip
ISP provides a very smooth AE (Auto Exposure) and accurate AWB (Auto White Balance)
control. It provides various data formats, such as Bayer RGB, RGB565, YCbCr 4:2:2 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.
