STEP 3. Check the effect of the gain correction operation by enabling Software Gain
Correction. The displayed image should appear very uniformly illuminated,
except for any bad pixels that may be present. Do not worry about these
pixels, as the bad pixel correction map will deal with them.
NOTE: If you want to make sure that all the bad pixels you see are marked for repair,
follow the directions in APPENDIX C.
STEP 4. To send the new gain correction table to the Pyrocam Flash memory, click on
the Write Flash button. The mouse pointer will become an hourglass while
the new table is programmed into the Pyrocam. When it returns to an arrow,
the Flash programming has completed.
STEP 5. To save the new gain correction table to a file (highly recommended), enter a
file name in the Save and Load section and click the Save button. A
standard file-naming window will appear. Make sure the file name is correct,
navigate to the desired save location, and click Save.
STEP 6. Close the Gain Correction Dialog window to end the gain correction
process.
STEP 7. To check the effects of the updated gain correction table, turn on both bad
pixel and gain correction in the Pyrocam by clicking on the Bad Pixel
Correction button and the Gain Correction button. Observe the effects of
the corrections in the 2D beam display. If all went according to plan, the
displayed image should show no visual indications of defective pixels and
show a uniform illumination.
