Acquired IR image using videoinput seems to be wrong

I want to retrieve an image from an thermal camera (Optris PI400). This fails, see the attached picture.

imaqreset

device = imaqhwinfo('winvideo', 2);

vidobj = videoinput('winvideo', 2);  
img = getsnapshot(vidobj);
figure
imagesc(img)

For device I get this:

This is the picture I get:

Does anybody know, what might be the problem?

You are displaying a YUY2 image as if it were RGB.

If it were a normal YUY2 image then I would suggest https://www.mathworks.com/help/imaq/returnedcolorspace.html but with it being IR, you probably need to do some other kind of processing of the panes, such as displaying them separately.
