The Advanced Camera Settings library is used by application developers to enable camera users to configure camera settings and by device creators to define default and mandatory software and hardware configuration settings. </p> <section><title>Purpose</title> <p>Advanced Camera Settings provides domain specific getters and setters for well known camera hardware settings.

You can get a list of UIDs of the supported and currently active settings, so that a user interface of the available options can be updated accordingly.
