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.
