OV7670 Camera Module

The OV7670 is a compact VGA camera module based on the OmniVision OV7670 image sensor. It provides a single-chip VGA camera and image processor capable of up to 30fps at 640×480 resolution, with multiple output formats including RGB565, YUV, and raw RGB.

Controlled via the SCCB interface (I²C compatible), the sensor offers full control over image quality including gamma correction, white balance, saturation, and sharpness. Built-in ISP functions handle automatic exposure, gain control, white balance, and noise reduction.
