The camera module is easily controlled by commands to perform the required task controlled by MCU (Arduino, ESP32, Raspberry). The OV7670 camera module allows you to capture images in VGA format (640×480). It can perform some initial processing and transfer the images to microcontrollers, such as the ESP32, STM, Arduino.
The OV7670/OV7171 CAMERA 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 CAMERA CHIPs 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.
