+ 14-bit Bayer formats expanded to 16 bits
+
+
+ Description
+
+ These four pixel formats are raw sRGB / Bayer formats with
+14 bits per colour. Each colour component is stored in a 16-bit word, with 2
+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:
+
+
+ V4L2_PIX_FMT_SBGGR14 4 × 4
+pixel image
+
+
+ Byte Order.
+ Each cell is one byte, the 2 most significant bits in the high
+ bytes are 0.
