OV7660/OV7161 CMOS VGA (640x480) CAMERACHIPTM with OmniPixelTM Technology Applications
* * * * Cellular and Picture Phones Toys PC Multimedia Digital Still Cameras
The OV7660/OV7161 CAMERACHIPTM is a low voltage CMOS image sensor that provides the full functionality of a single-chip VGA camera and image processor in a small footprint package. The OV7660/OV7161 provides full-frame, sub-sampled or windowed 8-bit images in a wide range of formats, controlled through the Serial Camera Control Bus (SCCB) interface. This product has an image array capable of operating at up to 30 frames per second (fps) in VGA with complete user control over image quality, formatting and output data transfer. All required image processing functions, including exposure control, gamma, white balance, color saturation, hue control and more, are also programmable through the SCCB interface. In addition, OmniVision CAMERACHIPs use proprietary sensor technology to improve image quality by reducing or eliminating common lighting/electrical sources of image contamination, such as fixed pattern noise (FPN), smearing, blooming, etc., to produce a clean, fully stable color image.

Functional Description
Image Sensor Array
The OV7660/OV7161 sensor has an active image array of 640 columns x 480 rows (307,200 pixels). Figure 3 shows a cross-section of the image sensor array.
In addition to the A/D conversion, this block also has the following functions: * Digital Black-Level Calibration (BLC) * Optional U/V channel delay * Additional A/D range controls In general, the combination of the A/D Range Multiplier and A/D Range Control sets the A/D range and maximum value to allow the user to adjust the final image brightness as a function of the individual application.

Timing Generator
In general, the timing generator controls the following functions: * Array control and frame generation (7 different format outputs) * Internal timing signal generation and distribution * Frame rate timing * Automatic Exposure Control (AEC) * External timing outputs (VSYNC, HREF/HSYNC, and PCLK)
This block controls the interpolation from Raw data to RGB and some image quality control. * Edge enhancement (a two-dimensional high pass filter) * Color space converter (can change Raw data to RGB or YUV/YCbCr) * RGB matrix to eliminate color cross talk * Hue and saturation control * Programmable gamma control * Transfer 10-bit data to 8-bit
Output Formatter
This block controls all output and data formatting required prior to sending the image out.
Analog Signal Processor
This block performs all analog image functions including: * Automatic Gain Control (AGC) * Automatic White Balance (AWB)
Digital Video Port
Register bits COM2[1:0] increase IOL/IOH drive current and can be adjusted as a function of the customer's loading.
A/D Converters
After the Analog Processing block, the bayer pattern Raw signal is fed to a 10-bit analog-to-digital (A/D) converter shared by G and BR channels. This A/D converter operates at speeds up to 12 MHz and are fully synchronous to the pixel rate (actual conversion rate is related to the frame rate).
SCCB Interface
The Serial Camera Control Bus (SCCB) interface controls the CAMERACHIP operation. Refer to OmniVision Technologies Serial Camera Control Bus (SCCB) Specification for detailed usage of the serial control port.
