13description:
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.
