Interleaved grey-scale image, e.g. from a stereo-pair


Description
===========

This is a grey-scale image with a depth of 8 bits per pixel, but with
pixels from 2 sources interleaved. Each pixel is stored in a 16-bit
word. E.g. the R200 RealSense camera stores pixel from the left sensor
in lower and from the right sensor in the higher 8 bits.

**Byte Order.**
Each cell is one byte.
