   14 
   15   CCS (Camera Command Set) is a raw Bayer camera sensor standard defined by the
   16   MIPI Alliance; see
   17   <URL:https://www.mipi.org/specifications/camera-command-set>.
   18 
   19   SMIA (Standard Mobile Imaging Architecture) is an image sensor standard
   20   defined jointly by Nokia and ST. SMIA++, defined by Nokia, is an extension of
   21   that.
