ABSTRACT:
An apparatus for the acquisition and restoration in real time of a framed picture as disclosed. This apparatus utilizes an automaton and a slave circuit of the automaton for the addressing of a memory through the use of digital values from an analog-digital converter for analog picture acquisition signals. The digital values are processed and supplied to a digital-analog converter for the display of a picture on a display unit. Addressing outputs of the automaton are connected to the memory with the outputs of the slave circuit being connected to the synchronization inputs of both the analog-digital and the digital-analog converters in order to display picture corresponding to the processed digital values.
