V4L2_PIX_FMT_SGRBG10P V4L2_PIX_FMT_SGBRG10P V4L2_PIX_FMT_SBGGR10P 10-bit packed Bayer formats
2.6.1.3.1. Description¶
These four pixel formats are packed raw sRGB / Bayer formats with 10 bits per sample. Every four consecutive samples are packed into 5 bytes. Each of the first 4 bytes contain the 8 high order bits of the pixels, and the 5th byte contains the 2 least significants bits of each pixel, in the same order.
Each n-pixel row contains n/2 green samples and n/2 blue or red samples, with alternating green-red and green-blue rows. They are conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of a small V4L2_PIX_FMT_SBGGR10P image:
