2.5.2. V4L2_PIX_FMT_SRGGB8 (‘RGGB’), V4L2_PIX_FMT_SGRBG8 (‘GRBG’), V4L2_PIX_FMT_SGBRG8 (‘GBRG’), V4L2_PIX_FMT_SBGGR8 (‘BA81’),¶
8-bit Bayer formats
2.5.2.1. Description¶
These four pixel formats are raw sRGB / Bayer formats with 8 bits per sample. Each sample is stored in a byte. Each n-pixel row contains n/2 green samples and n/2 blue or red samples, with alternating red and blue rows. They are conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of a small V4L2_PIX_FMT_SBGGR8 image:
Byte Order. Each cell is one byte.
