Iris
The GC series cameras support
All
NOTE: The camera must be acquiring images in order for the auto iris algorithm to update.
IrisAutoTarget – In percent. Controls the general lightness or darkness of the auto iris feature; specifically the target mean histogram level of the image, 0 being black, 100 being white.
IrisMode – Sets the
Disabled – Turn off the video
Video – Turn on the video
VideoOpen – Fully open the iris.
VideoClosed – Full close the iris.
IrisVideoLevel – In 10 mV units. This attribute reports the strength of the video signal coming from the camera.
IrisVideoLevelMax - In 10 mV units. Limits the maximum driving voltage for closing the lens iris. Typically this will be 150, however it may vary dependent on the lens reference voltage.
IrisVideoLevelMin - In 10 mV units. Limits the minimum driving voltage for opening the lens iris. Typically this will be 0.
WhiteBalance
Auto
The following parameters are used to control the way that the Auto whitebalance function operates.
WhitebalAutoAdjustDelay - Currently unimplemented.
WhitebalAutoAdjustTol - A threshold. This parameter sets a range of scene color changes in which the automatic whitebalance will not respond. This parameter can be used to limit whitebalance setting changes to only larger variations in scene color.
WhitebalAutoAlg - The whitebalance algorithm is fixed as "Mean", that is, the algorithm uses the mean histogram value for the red and blue channels in its calculations.
WhitebalAutoRate - In percent. Determines how fast the Auto Whitebalance updates.
WhitebalMode
Manual – Auto whitebalance is off. Whitebalance can be adjusted directly by changing the WhitebalValueRed and WhitebalValueBlue parameters.
Auto - Whitebalance will continuously adjust according to the current scene. The Auto function operates according to the Auto and DSP controls
AutoOnce – A command (of type Enumeration in PvAPI). A single iteration of the auto whitebalance algorithm is run, and then the camera reverts to Manual WhitebalMode. The AutoOnce function operates according to the Auto and DSP controls
