Linea Lite GigE Series Camera
Verify a Bright Acquisition
Point the camera at a diffused light source or evenly lit white wall with no shadows falling on it.
Click the grab button, followed by ‘histogram’ in the drop
-down menu. Use the lens iris to adjust
for a bright gray approximately pixel value 200 (for 8-bit pixels). The following figure displays a
histogram while grabbing a bright gray image.
Important:
In this example, the
average
pixel value for the frame is bright gray.
Note
: Sensors may show a much higher maximum or lower minimum pixel value due
to one or more "hot or dead pixels". The sensor specification accounts for a small
number of hot, stuck, or dead pixels (pixels that do not react to light over the full
dynamic range specified for that sensor).
When the bright gray acquisition setup is complete, note the camera and lens iris position for
repeatability in the future.
