22 These four pixel formats are raw sRGB / Bayer 22 These four pixel formats are raw sRGB / Bayer formats with 14 bits per
23 colour. Each sample is stored in a 16-bit word 23 colour. Each sample is stored in a 16-bit word, with two unused high
24 bits filled with zeros. Each n-pixel row conta 24 bits filled with zeros. Each n-pixel row contains n/2 green samples
25 and n/2 blue or red samples, with alternating 25 and n/2 blue or red samples, with alternating red and blue rows. Bytes
26 are stored in memory in little endian order. T 26 are stored in memory in little endian order. They are conventionally
27 described as GRGR... BGBG..., RGRG... GBGB..., 27 described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an
