A system for processing graphical data in the form of images recorded on 35-mm film is described; it is based on an Elektronika-60 microcomputer and meets the requirements of being self-contained and transportable while maintaining a high film-input rate (25 mm/sec) and quality of image processing (measurement accuracy of 0. 05 mm along the film and 0. 2 mm across it). Software support is developed with the aid of a punch-tape operating system.
