ABSTRACT:
A method and an apparatus for storing in a digital memory the information obtained by comparing by means of a logical operator any information previously stored in said memory with the information originating from a television camera. Specifically a method and an apparatus for storing in a digital memory the plane projection of a trace left by a particle on a transparent medium or the plane projection of the trajectory of an object moving through the space along with the stationary objects with respect to which said object is moving or without said stationary objects.
The apparatus comprises a television camera for scanning the picture to be memorized, an analog-digital converter for converting the signals from the telecamera into digital signals, a digital memory for processing said digital signals, an inclusive-OR logical operator for supplying to said memory the image of a trace or trajectory along with the background of stationary objects, an exclusive-OR for forming in said memory the image of a trajectory without the stationary background, a switch for shifting the apparatus from operating through said inclusive-OR or through said exclusive-OR and vice-versa.
