* Available value is
listed in
"capability_image_c
<n>_exposure_ma
xrange"
etc.
* 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_maxran
ge" != "-" and
"capability_image_c<n>_exposure_rangety
pe" is "onevalue".
* We support this parameter when the
version number (httpversion) is equal or
greater than 0302a.

BLC.
