+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.
