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