Verify a Bright Acquisition
Point the camera at a diffused light source or evenly lit white wall with no shadows falling on it.
Click Grab, followed by Statistics. 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.
Figure 45: CamExpert Statistics Dialog – Verifying Bright Acquisition
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.
