Early Electronic Image Capture

I have something similar in a Polaroid product - a high-res B&W CRT in a box with an internal motorized color wheel and a video input. You provide a 15KHz (NTSC freq) RGB video stream to the box, press the "freeze" button, which captures an image internally, then it shows 4 different views through the 4 portions of the wheel and exposes a frame of film 4 times before advancing. I picked it up at Dayton, natually, and managed to come across the essential control panel later. I've run a few rolls of film through it, mostly to create interstitial slides for slide shows. It's not as high-res as sending JPEGs out to a service bureau, but I've used my Amiga to render text on a pleasing blue background, then exposed some nice Fujichrome 100 slide film for a total cost of under $10/roll, or about $0.28 per background slide.
