Bad Pixel Control: All defective pixels are identified by FLIR as part of the standard factory Acceptance
Test. However, it is possible that a camera in the field may have a pixel that needs replacing. Usually these
are flickering pixels, or pixels which have developed an offset, and may appear as white on a black
background.
Note: When eliminating pixels, it is important that the camera is not inverted and not reverted.
The bad pixel kill procedure involves taking a snapshot of a scene that clearly shows the bad pixel. Once
a snapshot is taken, the Retrieve Snapshot button will open a separate window that has pane on the right
that shows a reticle with a zoomed subframe. Use the mouse, then the arrow keys to fine tune the cursor
location until the offensive pixel is between the crosshairs. The zoom value of the subframe can be adjusted
using the slider bar. Use the Enter key to select the pixel and add it to the pixel kill list.
Bad pixels can also be manually added to the list by entering the row and column, and clicking Add.
Bad pixels can be removed from the Kill Pixel List by selecting them one by one and clicking Remove
Selected Pixels. Use Ctrl to select multiple pixels or Shift to select a group of pixels to be removed. There
is also a Remove All Pixels from the List button that will clear the list.
Once the list is populated, click Set Bad Pixels to add these pixels to the camera's bad pixel map. This will
immediately affect the video output. Verify that the pixel is being replaced and click Save Bad Pixels to
save this change in the camera. If the pixels are not being replaced, reset the camera using the Setup Tab to
revert back to the previous state.
The bad pixel map currently in the camera can always be displayed by pressing the Retrieve BP Map
button.
FPA Temperature: The camera's Focal Plane Array (FPA) temperature in Celsius is reported in this edit
box. The factory setting for this target FPA temperature is 20°C, as managed by the TE Cooler in the VPA.
If the camera cannot maintain this temperature due to extreme environmental temperatures or to insulating
mounting configurations then the camera will automatically step to the best TEC temperature that can be
maintained and will display the actual temperature of the FPA in this edit box.
