Hi, as a newbi to open cv I have this question. I am using a e-con see3cam cu40 IR camera to capture images. All images I took inside my room are okay while I try to take outside pictures in a sunny day everything goes white. How do I correct this in open CV? Thank you very much!

Please post your code snippet. Try to check returned Mat type (m.channels(), m.depth()). Check returned values range with minMaxIdx() function (https://docs.opencv.org/4.1.0/d2/de8/...). Try to rescale pixel values for display (http://answers.opencv.org/question/86...).

Probably is just overexposed. Can you set the exposure time?

If you capture the image In the outdoor environment, more light will falling on the sensor that's why image get over exposed. Please reduce the exposure value and test the camera.
