Indeed, you're right.

Has anybody already implemented something > similar? The camera has a hardware manual focus. Autofocus is implemented in the Windows driver, and is of course missing from the Linux driver. There are two things to implement in Linux to get something similar. The first one is to implement manual focus into the driver. This shouldn't be difficult and I'll have a go at it. The second one is much more complex. You'll have to come up with a userspace image processing algorithm to compute focus values from the video. I have no experience with that.
