Abstract

a. Système d'examen ou de reconnaissance d'objets. b. Un dispositif de détection capte un objet à examiner et délivre un signal video complexe. Ce signal est séparé en des signaux de synchronisation horizontale et verticale et un signal video. Un signal de contrôle comparatif est élaboré à partir des signaux de synchronisation horizontale et verticale et le signal video est comparé avec un signal de référence seulement pendant une durée déterminée par ce signal de contrôle comparatif pour produire un signal de déclenchement de l'examen. c. Examen de très petits objets transportés sur des bandes transporteuses.at. System of examination or recognition of objects. b. A detection device picks up an object to be examined and delivers a complex video signal. This signal is separated into horizontal and vertical sync signals and a video signal. A comparative control signal is generated from the horizontal and vertical synchronization signals and the video signal is compared with a reference signal only for a period of time determined by that comparative control signal to produce a test trigger signal. vs. Examination of very small objects transported on conveyor belts.
