Hi,
I am needing a image of a webcam in Matlab. Therefore I use the command cam=webcam(2) For changing the resolution I am using cam.Resolution = '1920x1080' The problem now is that if I am loading an image using image = snapshot(cam); the resolution is always 480x640 not the resolution that I entered before. Does anybody has an idea why?
Thank you=)

Are you changing it to one of the object's available resolutions?
