OV7670 Camera Module
Internal Reference:
KIT.CAMERA.OV7670
General Description
The OV7670/OV7171 CAMERACHIPs 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 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 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.
