Title (EN) TELEPHOTO SENSOR TRIGGER IN A SOLID STATE MOTION ANALYSIS SYSTEM
(FR) CIRCUIT DE DECLENCHEMENT DE CAPTEUR TELEPHOTOGRAPHIQUE, MONTE DANS UN SYSTEME D'ANALYSE DE MOUVEMENT A SEMI-CONDUCTEURS
Abstract:
(EN) A solid state motion analysis system (10) stores images of an event at a fast frame rate and plays back the images at a slower frame rate to facilitate analysis of the event. The motion analysis system (10) includes a solid state imager (12) which is selectively operable at different frame rates and further includes a solid state memory (32) for storing a plurality of image frames. A trigger circuit (50) includes a telephoto sensor (48) which senses a change in a scene (14) being imaged by the motion analysis system (10). When a scene change is sensed, the trigger circuit (50) produces a trigger signal to alter the mode of operation of the motion analysis system (10). Thus, storage of image frames in the solid state memory (32) may be started or stopped when a change in luminance of the scene (14) occurs.
(FR) Un système d'analyse de mouvement (10) à semi-conducteurs stocke des images d'un événement à une haute fréquence d'image et repasse les images stockées à une fréquence d'image inférieure pour faciliter l'analyse de l'événement. Le système d'analyse de mouvement (10) comprend un imageur (12) à semi-conducteurs qui peut fonctionner de façon sélective, à différentes fréquences d'image et comprend, en outre, une mémoire (31) à semi-conducteurs destinée à stocker une pluralité d'images. Un circuit de déclenchement (50) comprend un capteur téléphotographique (48) qui détecte un changement dans un scène (14) enregistrée par le système d'analyse de mouvement (10). Lorsqu'un changement est détecté dans une scène, le circuit de déclenchement (50) produit un signal de déclenchement pour modifier le processus de fonctionnement du système d'analyse de mouvement (10). Ainsi le stockage des images dans la mémoire (32) à semi-conducteurs peut-être lancé ou arrêté lorsqu'une modification de la luminance de la scène (14) se produit.
