+14-bit Bayer formats expanded to 16 bits
|
|
+
|
|
+
|
|
+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.
