GC0308 has an active image array of 648x488 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 analog signal is transferred to digital signal by
10 bit A/D converter. The digital signals are processed in the ISP Block, including
Bayer interpolation, De-noise, color correction, gamma correction, data format
conversion and so on. Users can easily control these functions via two-wire serial
interface bus.
