CameraOffset Property 
 
CameraOffset Property 
 
Applies To 
Vision Sequence 
 
Description 
Specifies the offset for the camera used in the current sequence.  The offset is the lower limit of the digital 
values that will be assigned to the video signal in the A/D converter. (Also known as Brightness.)   
 
Usage 
VGet  Sequence.CameraOffsetvar 
VSet  Sequence.CameraOffsetvalue 
Sequence  Name of a sequence or string variable containing a sequence name. 
var 
Integer variable that will contain the value of the property. 
value 
Integer expression for the new value of the property. 
 
Values 
Integer value from 0 - 255 
Default: 0 
 
Remarks 
The CameraOffset property is normally left at a value of 0.   
Change the CameraOffset property when you want to change the brightness of an acquisition.  Adjusting 
the CameraOffset property allows you to select the lower and upper limits (saturation points) at which 
differentiation of assigned digital values begins and ends.  Due to variations in camera components, the 
lowest digital values that can be converted may not be precisely 0, but will be close to 0.  All signal 
voltages that exceed the upper limit of the dynamic range are assigned the highest digital value possible.
