1. Sensor Overview
1.1 General Description
The GC0329 features 640V x 480H resolution with 1/9-inch optical format, and
4-transistor pixel structure for high image quality and low noise variations. It
delivers superior image quality by powerful on-chip design of a 10-bit ADC, and
embedded image signal processor.
The full scale integration of high-performance and low-power functions makes
the GC0329 best fit the design, reduce implementation process, and extend the
battery life of cell phones, PDAs, and a wide variety of mobile applications.
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. It has a commonly used two-wire serial
interface for host to control the operation of the whole sensor.

1.5 Block Diagram
GC0329 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, denoise, color correction, gamma
correction, data format conversion and so on. Users can easily control these
functions via two-wire serial interface bus.
