Synchronous image input method and system therefor

摘要

This invention relates to an image input method and a system therefor for raster-scanning an object which makes periodical movements and for obtaining thermal images thereof. The invention comprises the steps of taking in such periodical movements of the object as trigger signals for each revolution period, controlling the scanning speed of a raster scanning mechanism in accordance with the period of such trigger signals, reading arbitrary and different partial images for each of the raster scanning by the mechanism using the trigger signals as references when synchronization is fully established, and synthesizing imagers for one frame to display thermal images on a TV monitor screen.
