Description
A CMOS VGA (640×480) camera chip refers to a type of image sensor integrated circuit that is commonly used in low-resolution digital cameras, webcams, and other imaging devices.
The 0V7670 / OV7171 CAMERA CHIP image sensor is a low voltage CMOS device that provides the full functionality of a single-chip VGA camera and image processor in a small footprint package. The OV7670 / OV7171 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 sensors 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.

6. Saturation level auto adjust (UV adjust)
Block Diagram:
1. Resolution: The camera chip is designed to capture images at VGA resolution, which is 640×480 pixels. This resolution is suitable for basic imaging and video applications.
2. Image Sensor: The heart of the camera chip is its CMOS image sensor. CMOS sensors use an array of pixels to capture light and convert it into electrical signals. Each pixel typically consists of a photodiode and associated electronics for signal processing.
Applications:
• Cellular and Picture Phones
• Toys
• PC Multimedia
• Digital Still Cameras
