+Interleaved grey-scale image, e.g. from a stereo-pair
+
+
+Description
+===========
+
+This is a grey-scale image with a depth of 12 bits per pixel, but with
+pixels from 2 sources interleaved and bit-packed. Each pixel is stored
+in a 24-bit word in the little-endian order. On a little-endian machine
+these pixels can be deinterlaced using
+
+.. code-block:: c
+
+ __u8 *buf;
+ left0 = 0xfff & *(__u16 *)buf;
+ right0 = *(__u16 *)(buf + 1) >> 4;
+
+**Bit-packed representation.**
+pixels cross the byte boundary and have a ratio of 3 bytes for each
+interleaved pixel.
