OV7670 概述

OV7670 image sensor is a low voltage CMOS sensor that provides the full functionality of a single-chip VGA camera and image processor in a small footprint package. The OV7670 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.

OV7670 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.

OV7670 特性

• Output support for Raw RGB, RGB (GRB 4:2:2, RGB565/555/444), YUV (4:2:2) and YCbCr (4:2:2) formats
• Image quality controls including color saturation, hue, gamma, sharpness (edge enhancement), and anti-blooming
• Saturation level auto adjust (UV adjust)
• Edge enhancement level auto adjust
