I'm reviewing the CHDK scripting options for a Canon A480, and I'm not sure what I want is doable
I'd like to scan 8mm film in. I was thinking by moving film SLOWLY across either the CCD (directly over top of it) or the camera's field of view. Perhaps CHDK could determine when a new frame is positioned more-or-less correctly.
There's a nice sprocket hole on the side of 8mm film, so I really only need to detect when a range of pixels is bright (after having been dark). I could later use PC image stabilization software against sprocket hole positions to make all the frames line up perfectly... so it doesn't have to be perfect. But I would like the camera to snap 1 photo per frame of film.
I assume I would need "MX3's Motion Detection Build" for that? How do I acquire MX3 for A480?
My attempt was changing this URL...
...and well nope. Is it possible to get MX3 on the Canon A480?
Do I really need it, or is there some other way of detecting that the film is in a good position to snap a photo of a frame?
Also, it is not clear to me how to push a photo that has just been taken on to a PC via USB cable
. Does that need to be remotely scripted from the PC? I was hoping to have all the decision making in the camera itself. And a memory card will quickly fill up.
Thanks for any direction on this. -Gord
