- Adjust camera settings: You mentioned that you are able to access the camera's properties using the gigecam adaptor in MATLAB. Try adjusting the camera's gain, exposure time, and black level settings to see if it improves the dynamic range of the image.
- Check temperature: Make sure that the camera is at the correct operating temperature. Thermal cameras can be sensitive to temperature fluctuations, which can affect the image quality.
- Check the calibration: Ensure that the camera is calibrated correctly. Thermal cameras can be calibrated to provide accurate temperature measurements, and a poorly calibrated camera may result in distorted images.
- Consider using a filter: Thermal cameras are sensitive to infrared radiation, which can affect the image quality. Try using a filter to block out unwanted radiation.
- Contact the manufacturer: If you are still having issues, consider contacting the manufacturer for support. They may be able to provide more specific guidance on how to improve the image quality.
GigE Pyrocam III: Mono16 Pixel vales always at extremes close to 0 or 65535

Hi, I am trying to access video from a Pyrocam camera from Matlab using GigE Vision Adaptor. I am able to connect to the camera, and get the frames or video. However the pixel values are very saturated at either extremes of being close to zero (<10) or 65535 (like 65525-65535), My laser beam is off and I checked with the Pyrocam software the image is way below saturation.
I am aware that Pyrocam is a thermal based camera which does not always has a frame ready for grabbing (the camera runs a chopper at 50Hz and 50/50 duty cycle to provide the time signal) but I don't know what I need to do to get a correct frame. I can access to the camera via gigecam and set properties like turning the chopper on off or varying its speed any maybe a few other things.
Thank you for your help.

Hi,
It sounds like you are experiencing issues with the dynamic range of your Pyrocam camera. It's possible that the pixel values you are seeing are due to the camera's sensitivity to thermal radiation.
Here are a few things you can try to improve the image quality:
Hope it helps!!
