Bayer sensor

Most camera sensors use a single layer of photosites (pixels). These are only sensitive to light, not color, so a mosaic of red, green and blue filters (the ‘bayer pattern’) is placed on top of the sensor’s photosites so that individually they capture red, green or blue light. When the camera processes the sensor data to produce an image, it ‘demosaics’ the red, green and blue data, using color information from surrounding photosites to ‘interpolate’ full color data for each pixel.

June 14, 2019 by Rod Lawton
