| 13 | <para>This is commonly the native format of digital cameras, | ||
| 14 | reflecting the arrangement of sensors on the CCD device. Only one red, | ||
| 15 | green or blue value is given for each pixel. Missing components must | ||
| 16 | be interpolated from neighbouring pixels. From left to right the first | ||
| 17 | row consists of a red and green value, the second row of a green and | ||
| 18 | blue value. This scheme repeats to the right and down for every two | ||
| 19 | columns and rows.</para> | ||
