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.
