Raw pixel

Raw pixel
value(8bit): 45
Shift pixel
value(8bit): 181
Example 3: Digital Shift by 1, 12-bit Image Data, High Value
Assume that your camera is using a 12-bit pixel format. Also assume that one of your original pixel values
is 2839.
Raw pixel
value: 2839
Shift pixel
value: 4095
If you apply digital shift by 1 to this pixel value, the resulting value is greater than the maximum possible
value for 12-bit pixel formats. In this case, the value is set to the maximum value, i.e., all bits are set to 1.

Acquisition Status
The Acquisition Status feature can determine whether the camera is waiting for trigger signals. This is
useful if you want to optimize triggered image acquisition and avoid over triggering.
To determine if the camera is currently waiting for trigger signals.
a)
Set the AcquisitionStatusSelector parameter to the expected trigger type. Two trigger types are
available: FrameTriggerWait and AcquisitionTriggerWait. For example, if you want to determine if the
camera is waiting for FrameStartTrigger signals, set the AcquisitionStatusSelector to
FrameTriggerWait. If you want to determine if the camera is waiting for FrameBurstStartTrigger
signals, set the AcquisitionStatusSelector to AcquisitionTriggerWait.
b)
If the AcquisitionStatus parameter is true, the camera is waiting for a trigger signal of the trigger type
selected. If the AcquisitionStatus parameter is false, the camera is busy.
