BF3710 has an active image array of 1297x817 pixels. The active pixels are read out progressively
through column/row driver circuits. In order to reduce fixed pattern noise, CDS circuits are adopted. The
ASP block is mainly used to control global gain and color gains to get accurate exposure and white
balance under different light condition and color temperature. The analog signal is transferred to digital
signal by A/D converter. The digital signals are processed in the ISP Block, including Bayer interpolation,
low pass filter, color correction, gamma correction, skin detection, scaling and data format conversion
and so on. Users can easily control these functions via two-wire serial interface bus.
