* Available value is
listed in
"capability_image_c
<n>_exposure_ma

* This parameter may also restrict image
frame rate from sensor due to sensor
generates a frame per exposure time. Ex: If
this is set to 1/5s ~ 1/8000s and camera takes
1/5s on the night, then sensor only outputs 5
frame/s.
* Only available when
"capability_image_c<n>_exposure_maxrang
e" != "-"
* Only valid when "piris_mode"=manual or
"irismode"=fixed
* Only available when
"capability_image_c<n>_exposure_rangetyp
e" is "twovalues".
