OV2640 Camera Module

The OV2640 image sensor has 2 million pixels (1632x1232 pixels), its size is small, the working voltage is low, and it provides all the functions of a single-chip UXGA camera and image processor. Through SCCB bus control, it can output 10-bit sampling data of various resolutions in the form of whole frame, sub-sampling, windowing, etc. The maximum UXGA image of this product is 15 frames per second. The user can fully control the image quality, data format and transmission method. All image processing functions including gamma curve, white balance, saturation, chroma, etc. can be programmed through the SCCB interface. OmmiVision image sensor uses unique sensor technology to improve image quality and obtain clear and stable color images by reducing or eliminating optical or electronic defects such as fixed pattern noise, tailing, floating, etc.

This imaging sensor is suitable for ESP32-CAM development module.
