OV7670 Camera Module

Description:-

OV7670 Camera Module is a precise small size, high sensitive and low voltage CMOS image Sensor module for capturing and processing the image. It is based on OV7670 image sensor. Through SCCB bus control, the sensor can output the whole frame, sampling, and various resolution of 8 bits of data. The product VGA image can reach up to a maximum of 30 frames per second. Users can completely control the image quality, data format and transmission mode. All the process of image processing functions can be through the SCCB programming interface, including gamma curve, white balance, saturation and chroma.

The OV7670 is a low cost image sensor DSP that can operate at a maximum of 30 fps and 640 x 480 (“VGA”) resolutions, equivalent to 0.3 Megapixels. The captured image can be pre-processed by the DSP before sending it out. This preprocessing can be configured via the Serial Camera Control Bus (SCCB).

In addition, OmmiVision image sensor has been in application of unique sensor technology, by reducing or eliminating the optical or electronic defect such as fixed pattern noise, tail, floating away, etc., to improve the quality of the image, and get the clear and stable color images.
