Description
|
|
===========
|
|
|
|
These four pixel formats are raw sRGB / Bayer formats with 14 bits per
|
|
colour. Each sample is stored in a 16-bit word, with two 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 a small V4L2_PIX_FMT_SBGGR14 image:
|
|
|
|
**Byte Order.**
|
|
Each cell is one byte, the two most significant bits in the high bytes are
|
|
zero.
