0012 Description
0013 ===========
0014
0015 Proprietary multi-planar format used by Intel SR300 Depth cameras, comprise of
0016 Infrared image followed by Depth data. The pixel definition is 32-bpp,
0017 with the Depth and Infrared Data split into separate continuous planes of
0018 identical dimensions.
0019
0020
0021
0022 The first plane - Infrared data - is stored according to
0023 :ref:`V4L2_PIX_FMT_Y10 <V4L2-PIX-FMT-Y10>` greyscale format.
0024 Each pixel is 16-bit cell, with actual data stored in the 10 LSBs
0025 with values in range 0 to 1023.
0026 The six remaining MSBs are padded with zeros.
0027
0028
0029 The second plane provides 16-bit per-pixel Depth data arranged in
0030 :ref:`V4L2-PIX-FMT-Z16 <V4L2-PIX-FMT-Z16>` format.
0031
0032
0033 **Frame Structure.**
0034 Each cell is a 16-bit word with more significant data stored at higher
0035 memory address (byte order is little-endian).
