Camera
The Camera system object accesses and sets some of the Impact camera’s parameters.
NOTES: The range of acceptable values for each input is determined by the camera type.
Changing any of these properties while the camera is being triggered and acquiring images can cause the
images to be corrupted. The camera should be offline or triggers should be stopped while these properties
are being changed.
Camera Properties Tab
Input Name What it is
Digital Shift Digital shift provides digital gain for the image.
Gain Gain adjusts the actual signal intensity from the camera.
NOTE: The gain setting for M-Series cameras is the “raw” gain setting,
not a percentage gain. The range of values will vary from camera to
camera. In all cases the recommended value is the minimum gain, which
corresponds to 0dB.
Offset Offset adjusts the zero grey-level setting for the camera. Adjusting the
offset causes the entire image to brighten or darken. Images become
darker as the offset is increased.
Shutter Speed Shutter Speed (Open Time) indicates the amount of time the shutter is
open. The higher the number, the longer the shutter is open and the
brighter the image.
