+Grey-scale image as a MIPI RAW14 packed array
+
+
+Description
+===========
+
+This is a packed grey-scale image format with a depth of 14 bits per
+pixel. Every four consecutive samples are packed into seven bytes. Each
+of the first four bytes contain the eight high order bits of the pixels,
+and the three following bytes contains the six least significants bits of
+each pixel, in the same order.
+
+**Byte Order.**
+Each cell is one byte.
