- orientation: The orientation of a device (typically an image sensor or a flash
LED) describing its mounting position relative to the usage orientation of the
system where the device is installed on.
Possible values are:
0 - Front. The device is mounted on the front facing side of the system.
For mobile devices such as smartphones, tablets and laptops the front side is
the user facing side.
1 - Back. The device is mounted on the back side of the system, which is
defined as the opposite side of the front facing one.
2 - External. The device is not attached directly to the system but is
attached in a way that allows it to move freely.
