Bayer Filter A Bayer filter is a color filter array commonly used in digital camera sensors to capture and reproduce color information in digital images. Named after its inventor, Bryce Bayer, this filter is composed of a grid of tiny color filters arranged in a specific pattern over the individual sensor pixels. The Bayer filter typically consists of red, green, and blue filters in varying proportions, allowing the camera sensor to capture color information by interpreting the intensity of light for each color channel. The raw data captured by the Bayer filter requires demosaicing during image processing to produce a full-color image. While widely used, the Bayer filter is just one of several color filter array designs employed in digital imaging, each with its own strengths and limitations. |
