OV7670 Camera Module DIY Guide




Here we introduced one OV7670 camera module just purchased online, including the communication of camera module and Arduino UNO, the using ways to take photo via camera module, and so on. This is an Arduino camera module,  adopted the Surveillance cameras digital image processing chip-OV0706, specially designed for image acquisition and processing application,  based on TTL communication interface, very convenient to connect with Arduino controller, able to read image and data via UART serial port, and then perform some image processing. This is a detailed DIY guide for the OV7670 TTL and UART camera, and you can also download the code from ElecFreaks.

Part 1   General description

This camera module can perform image processing such as AWB (auto white balance), AE (automatic exposure) and AGC (automatic gain control), for the video signal coming from CMOS sensor. What’s more, in fusion of other advanced technology such as image enhancement processing under low illumination, and image noise intelligent forecast and suppress, this module would output high quality digital video signals by standard CCIR656 interface. OV7670 built-in JPEG decoder supported reatime encoding for collected image, and external controller can easily read the M – JPEG video streams, achieving the camera design of double stream. OV7670 supported motion detection and OSD display function of screen characters and pattern overlay, capable of self-defining detection area and sensitivity.
