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 pi xel
value: 283 9
Shift pi xel
value:
409 5
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.
8.3.14. 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.
8.3.15. Black Level
The Black Level can change the overall brightness of an image by changing the gray values of the pixels
by a specified amount. Currently, the application range of the black level value can only be selected as all
pixels, and pixel selection is not supported.
The lower the black level, the darker the corresponding image, the higher the black level, the brighter the
corresponding image.
