|
|
||
| <para>The following four pixel formats are raw sRGB / Bayer formats with | ||
| 10 bits per colour. Each colour component is stored in a 16-bit word, with 6 | ||
| unused high bits filled with zeros. Each n-pixel row contains n/2 green samples | ||
| and n/2 blue or red samples, with alternating red and blue rows. Bytes are | ||
| stored in memory in little endian order. They are conventionally described | ||
| as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of one of these | ||
| formats</para> | ||

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