V4L2_PIX_FMT_INZI ('INZI')
**************************
Infrared 10-bit linked with Depth 16-bit images
Description
===========
Proprietary multi-planar format used by Intel SR300 Depth cameras, comprise of
Infrared image followed by Depth data. The pixel definition is 32-bpp,
with the Depth and Infrared Data split into separate continuous planes of
identical dimensions.
The first plane - Infrared data - is stored according to
:ref:`V4L2_PIX_FMT_Y10 <V4L2-PIX-FMT-Y10>` greyscale format.
Each pixel is 16-bit cell, with actual data stored in the 10 LSBs
with values in range 0 to 1023.
The six remaining MSBs are padded with zeros.
The second plane provides 16-bit per-pixel Depth data arranged in
:ref:`V4L2-PIX-FMT-Z16 <V4L2-PIX-FMT-Z16>` format.
**Frame Structure.**
Each cell is a 16-bit word with more significant data stored at higher
memory address (byte order is little-endian).
