11 Interleaved grey-scale image, e.g. from a stereo-pair
17 This is a grey-scale image with a depth of 12 bits per pixel, but with
18 pixels from 2 sources interleaved and bit-packed. Each pixel is stored
19 in a 24-bit word in the little-endian order. On a little-endian machine
20 these pixels can be deinterlaced using
26 left0 = 0xfff & *(__u16 *)buf;
27 right0 = *(__u16 *)(buf + 1) >> 4;
29 **Bit-packed representation.**
31 pixels cross the byte boundary and have a ratio of 3 bytes for each
44 - Y'\ :sub:`0left[7:0]`
46 - Y'\ :sub:`0right[3:0]`\ Y'\ :sub:`0left[11:8]`
48 - Y'\ :sub:`0right[11:4]`
