GC0308 -- VGA CMOS Image Sensor GC0308 DataSheet 3 / 32 1. Sensor Overview

1.1 General Description

The GC0308 features 640V x 480H resolution with 1/6.5-inch optical format, and 4-transistor pixel structure for high image qua lity and low noise variations. It delivers superior image quality by powerful on-ch ip design of a 10-bit ADC, and embedded image signal processor. The full scale integration of high-perfor mance and low-power functions makes the GC0308 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 provi des 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. The product is capable of operating at up to 30 frames per second at 24MHZ clock in VGA mode, with complete user control over image quality and data formatting.

1.5 Block Diagram

GC0308 has an active image array of 648x488 pi xels. The active pixe ls are read out progressively through column/row driver ci rcuits. In order to reduce fixed pattern noise, CDS circuits ar e 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 corr ection, gamma correcti on, data format conversion and so on. Users can easily cont rol these functions via two-wire serial interface bus.

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 read out fr om 0 to 647. If flip in column, column is read out from 647 to 0. If no flip in row, row is read out from 0 to 487. If flip in row, row is read out from 487 to 0. 2. Color Filter Spectral Characteristics The optical spectrum of color filters is shown below

GC0308 -- VGA CMOS Image Sensor GC0308 DataSheet 9 / 32 4. Timing Suppose Vsync is low active and Hsync is high active, a nd ouput format is YCbCr/RGB565, then the timing of vsync and hsync is bellowing: VtSt+8 Et HSYNC VSYNC Ft Bt Ft =VB+ Vt +8 （unit is row_time） VB = Bt + St + Et， Vblank/Dummy line ，setting by register 0x0f[7:4] and 0x02. Ft -> Frame time，one frame time Bt -> Blank time，Vsync no active time. St -> Start time，setting by register 0x0d. Et –> End time，setting by register 0x0e. Vt -> valid line time. VGA is 480，Vt=win_height-8，win_height is setting by register 0x09 和 0x0a（488）。 When exp_time <= win_height+VB ，Bt=VB-St-Et。Frame rate is controlled by window_height+VB。 When exp_time > win_height+VB ，Bt=exp_time-win_height-St-Et。Frame rate is controlled by exp_time。 The following is row_time calculate: row_time = Hb + Sh_delay + win_width + 4. Hb –> HBlank or dummy pixel，Setting by register 0x0f[3:0] and 0x01. Sh_delay -> Setting by register 0x12. win_width -> Setting by register 0x0b and 0x0c, win_width = 6final_output_width + 8. So for VGA, we should set win_width as 648.
