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 green and blue value, the second row of a red and | ||
18 | green value. This scheme repeats to the right and down for every two | ||
19 | columns and rows.</para> | ||
