Hi guys. Even at 5fps the ToUCam compresses data. I measured it a couple of years ago when I got curious. The "raw" frames from the camera that come down the bus at 5fps are about 1/2 the size that they should be. If you're curious then dig aropund on the net for the Linux driver and you'll find the source code to a decompression routine thats needed to recreate the frames.
The only way to get non-compressed data from a ToUCam is to use 320x240 image size. All 640x480 frames are compressed.
