MonkeyJam is a program that lets you get your drawings into the computer and then stick them together so that you can see your animation come to life. In other words, it's an exposure sheet driven digital pencil test program and a stop motion movie maker. You can capture from DV, video and webcam or import individual images. MonkeyJam allows you to adjust the timing, composits multiple layers and exports as AVI.
Or if you want to use what Alan suggested, then put a digital still camera on a tripod, set the image size to 640X480 and take a lot of still images. You will need software to put them all together so they become an AVI file, I would suggest using Img2Avi, which is a freeware download. You basically load all your stills pictures into it and it will assemble them and output an AVI file.
