-+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.
