Camera Active Area

The Camera Active Area represents the rectangular array of pixels containing active video that are delivered by the camera to the frame grabber.

Hactive_Px Limits

For both the area-scan and line-scan cameras, the MultiCam parameter Hactive_Px represents the number of columns of the Camera Active Area.

The following restrictions apply to the value of Hactive_Px:

Vactive_Ln Limits

For area-scan cameras only, the MultiCam parameter Vactive_Ln represents the number of rows of the Camera Active Area.

The following restrictions apply to the value of Vactive_Ln:

The following table defines explicitly the limits of Vactive_Ln for all possible combinations of:

#YRegions

# YTaps
