I'm using webcam() to acquire few images. I managed to get it working and export images in png format. However after the usage I can't reuse the webcam. (both internal and external to matlab) Either I have to restart matlab or reconnect the usb to get this fixed. I tried clear all, delete(mycam) options still the problem persists.
mycam = webcam;
preview(mycam)
closePreview(mycam)
img = snapshot(mycam);
imagesc(img)
delete(mycam)
clear all
I'm using matlab 2014b on win7. Is there another command to release/reset the webcam.

I have also encountered this kind of problem today. Just write "clear". It will delete all instances of the camera too, so the problem will be solved.
