Defective Pixel Repair

 

When operating a thermal imager, defective (dead) pixels (bright or dark dots with constant brightness) may become visible on the microbolometer.

Defective pixels on the microbolometer can increase in size relative to the digital-zoom power.

Accolade 2 LRF Pro thermal imaging binoculars allow the user to remove any defective pixels on the display, as well as cancel removal, via the device’s firmware.

  1. Press and hold down the Мenu (3) button to enter the main menu.
  2. Select the Defective Pixel Repair  menu item with the UP (2)/DOWN (5) buttons.
  3. Press briefly the Мenu (3) to open the submenu.
  4. Select the Defective Pixel Repair option by briefly pressing the Мenu (3) button.
  5. A marker (H)  appears on the left side of the display.
  6. On the right side of the display appears "magnifying glass" (G) – a magnified image in a frame with a fixed cross , designed for easier detection of a defective pixel and to match the pixel with the marker, horizontal and vertical arrows for X and Y axes (I) showing marker's movement.
  7. With a short press of the UP (2)/DOWN (5) buttons move the marker to align it with a defective pixel.
  8. Switch the direction of the marker from horizontal to vertical and vice versa with a short press of the Мenu (3) button.
  9. Align the defective pixel with the fixed cross in the frame – the pixel should disappear.
  10. Delete the defective pixel with a brief press of the REC (4) button.
  11. A brief message "OK" appears in the frame in case of success.
  12. Then you can delete another defective pixel by moving the marker along the display.
  13. Exit Defective Pixel Repair with a long press of the Menu (3) button.

Attention! The display of a thermal imager may have 1-2 pixels represented as bright white or color (blue, red) dots which cannot be deleted and are not a defect.
