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?
