GC0328 CMOS Image Sensor 1. Sensor Overview 1.1 General Description The GC0328 features 640V x 480H resolution with 1/6.5-inch optical format, and 4-transistorpixel 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 GC0328 fit the design, reduce implementation process, and extend the battery life of cell phones, PDAs, and a wide variety of mobile applications. The product is capable of operating at up to 30 fps at 24MHZ clock in VGA mode, which can be completely controlled by user over image quality and data format. 1.2 Features  Standard optical format of 1/6.5 inch  Various output formats: YCbCr4:2:2, RGB565, Raw Bayer  Support adjusting Voltage of IO  Windowing support  Horizontal /Vertical mirror  Image processing module  Package: CSP/wafer GC0328 Datasheet 3 / 49

GC0328 CMOS Image Sensor 1.5 Block Diagram R o w D e c o d e r Pixel Array 648H x 492V (640H x 480V) Column CDS Analog Processing 10bit ADC RESET MCLK SDA SCL Timing Control Configuration Registers AWB AEC Interpolation Image Signal Processing ‐ ‐ Denoise ‐ Gamma ‐ Edge enhance YUV/RGB data Output Mode & Sync Control PCLK VSYNC HSYNC GC0328 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, and color correction, gamma correction, data format conversion and so on. Users can easily control these functions via two-wire serial interface bus. GC0328 Datasheet 5 / 49

GC0328 CMOS Image Sensor 1.6 Pixel Array Pixel array is covered by Bayer pattern color filters. The primary color BG/GR array is arranged in line-alternating way. If no flip in column, column is readout from 0 to 647. If flip in column, column is read out from 647 to 0. If no flip in row, row is readout from 0 to 487. If flip in row, row is read out from 487 to 0. GC0328 Datasheet 6 / 49
