Applies To

Description
Determines whether video is cleared to black before the trigger is received.

VGet  Sequence.StrobeBlackVideo, var
VSet  Sequence.StrobeBlackVideo, value

Sequence

Name of a sequence or string variable containing a sequence name.

var

Boolean variable that will contain the value of the property

value

Boolean value or expression for the new value of the property.

Values

• 0 - False: Do not show black video before trigger.
• -1 - True: Show black video before trigger.

Default: True

Remarks
When RuntimeAcquire is set to Strobed, and VRun executes, by default the video display is cleared to black until a trigger is received. Then the grabbed image is displayed. For some applications, where VRun is executed rapidly in a loop, (such as conveyor tracking), it will be easier to see vision results if the video is not cleared to black after each VRun.
