Digitizing Your Granddad's Old Films with a Pi
summary
Describes a DIY film-scanning setup using a modified flatbed scanner with backlight and a stepper motor controlled by a Raspberry Pi running Java. Frames are detected by finding sharp transitions, scanned as RGB arrays processed in 14 MB chunks to avoid memory issues, and assembled into video with ffmpeg; the pipeline produces large raw data but can scan ~1.7 seconds per 10MP frame, trading speed and quality against professional services.
