Bayer Patterns

Colour cameras have a property known as a Bayer pattern. This pattern refers to how the pixels are arranged on the camera sensor itself in each 2x2 section of pixels. 

For example: if we look at the pattern 'RGGB', the pixels on the sensor are arranged in the pattern shown in the image below. 

This pattern extends over the entire sensor area. Each pixel is only sensitive to its respective type of light. The 'R' pixels are only sensitive to red light; the 'G' pixels are only sensitive to green light; the 'B' pixels are only sensitive to blue light.

When you save a frame as raw data, the pixel data will be recorded in the order of your bayer pattern. For example, if you are using Bayer8 as your pixel format and your camera pattern is RGGB, then the first byte will be a red pixel, the second byte will be a green pixel, and the the third byte will be a red pixel, etc. 

For more details on pixel formats, please see Image Data Formats. For more details on image formats such as raw data, please see Image File Formats.
