Videoface
Videoface Digitiser is a video digitiser interface for Sinclair ZX Spectrum home computer. It was produced by Data-Skip from The Netherlands and later on Romantic Robot from UK in 1987. It was originally sold for GBP 69, but price dropped to 30 GBP within few years.
Videoface takes signal from any video source with composite video out capability. It produces a 256 × 192 pixels, 4 bit screen. Scanning speed is just less than 4 frame/s. These screens can be saved as single pictures or animations with variable speed, and later loaded and edited in some drawing programs for the ZX Spectrum. During scanning, the contrast of the picture can be adjusted by turning the knob on top of the Videoface, and the picture can be shifted horizontally and vertically.
