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