2 Megapixel OV2640 Camera Module with STM32/C51 Driver Board

The OV2640 is a 1/4-inch CMOS UXGA (1632 x 1232) image sensor. The sensor's small size and low operating voltage provide all the features of a single UXGA camera and image processor. Through the SCCB bus control, it can output 8/10-bit image data of various resolutions such as full-frame, sub-sampling, zooming and windowing. The UXGA image of this product can reach up to 15 frames per second (up to 30 frames for SVGA and 60 frames for CIF). Users have complete control over image quality, data format and transmission. All image processing functions including gamma curve, white balance, contrast, chroma, etc. can be programmed via the SCCB interface. Image Sensors use unique sensor technology to improve image quality and reduce sharp and stable colour images by reducing or eliminating optical or electronic defects such as fixed pattern noise, smearing, and floating.
