Make sure you have the latest software for the galaxy.
If it is up to date then go into the app manager. (settings > applications > application manager (swipe over to the "all" tab) scroll down to the camera app and tap on it. force stop and clear data.
If you still have the issue then make sure the device is backed up, factory reset the device. If it still does it then replace the phone (if its under warranty)
