Abstract

The T.V. image point coordinate acquisition system has a window positioning circuit which is connected to a step detector and to a synchronising timer. This circuit is adapted to deliver an image frequency from signals received from the step detector and sync. timer. The system has an index shifting circuit which is controlled by the window positioning circuit. The index shifting circuit is designed to deliver, at image frequency, a signal which is shifted with respect to a signal emanating from the window positioning circuit. An index generator is connected at its input to the index shifting circuit and is designed to supply an index signal which defines an image point.
