| |
| <para>This is commonly the native format of digital cameras, |
| reflecting the arrangement of sensors on the CCD device. Only one red, |
| green or blue value is given for each pixel. Missing components must |
| be interpolated from neighbouring pixels. From left to right the first |
| row consists of a green and blue value, the second row of a red and |
| green value. This scheme repeats to the right and down for every two |
| columns and rows.</para> |
