Does any friend know how to fix dead pixels in FILR thermal imagers?

[龟苓膏]

Hello everyone. I currently have a FLIR E75 thermal camera with two hot dead pixels.

Every time I measure temperature, these pixels appear precisely at the boundary between high- and low-temperature areas.

When I enable high-temperature tracking, the camera automatically locks onto these dead pixels, resulting in temperature readings nearly 10°C higher than the actual values.

Does anyone know how to mask or disable these two dead pixels?

On these higher end models usually there is either a menu on the device or external PC software that lets the user "mask" dead pixels..

I don't have any FLIR products, as they are either highly restricted (ltd) or ludicrously expensive, so not sure how it works on Flir E75 but its a popular older model, so would guess some of the SW from FLIR would give that ability..

On iRay's higher end models, there looks to be a menu, where you have X & Y pixel control and what I guess is a manual UI-menu that can mask/map each single pixels to a user-created map, though nothing I have tried, as it's a relative new product and all the pixels are working well.

Dead pixel correction was part of the utilities provided in the Service menu of FLIR cameras back in 2013. Then we had the “E4 upgrade” and FLIR attempts to block such upgrades. Soon after, FLIR removed the Service Menu from their cameras. The Ex0 series still have the Service Menu but I believe it is not present, or not fully populated in the Ex5 series such as your E75. FLIR like to charge customers for “Calibration” of their cameras. Only very high end science cameras seemed to avoid this business practice, but I think even they are limited these days in terms of User calibration.

An example how its done on iRay''s stand-alone units.
I haven't tested it, but I would guess, its a menu for user-correct blind spot pixel correction?.
The user can then move the cursor with the small white-highlighted pixel around and mask with an X / Y pixel coordinate, and it will then  show how many you adjusted.. it shows "0" as it's a relatively new product, so no issues, but down the line, I reckon it can be handy, if it is intended as I speculate.?
Translated from Chinese, as these latest flip-models are not released on non-domestic markets...


It opens this UI where you manually X/Y adjust the white pixeldot-cursor around and mask/map (if needed)
very simple, but a crucial UI-tool if needed.
