<refpurpose>Interleaved grey-scale image, e.g. from a stereo-pair</refpurpose>
<para>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</para>

left0 = 0xfff &amp; *(__u16 *)buf;
right0 = *(__u16 *)(buf + 1) >> 4;
<title><constant>V4L2_PIX_FMT_Y12I</constant> 2 pixel data stream taking 3 bytes</title>
<title>Bit-packed representation</title>
<para>pixels cross the byte boundary and have a ratio of 3 bytes for each
interleaved pixel.
