1. An image data masking apparatus for use with image data processing apparatus comprising:

  • a television camera including a target screen formed of a number of sensor elements arranged in a matrix in horizontal and vertical directions, said sensors being adapted to pick up an object from said television camera and producing an image data signal of said object;

    a processor for processing the image data signal from said television camera;

    a memory circuit having a plurality of memory elements the number of which being equal to the number of said sensor elements and which are arranged in a matrix similar to that of said sensor elements, for storing the image data from said television camera, each of said memory elements having a specific address corresponding to a specific one of said sensors;

    scanning means for scanning the addresses of said memory elements and relaying both the horizontal and vertical synchronizing signals of said television camera in synchronization with the scanning of said sensor elements by said television camera so as to store image data from respective sensor elements on corresponding memory elements;

    means for producing signals, indicative of said sensors from which of said image data from said television camera are to be masked, and for storing said signals in memory elements of said memory circuit at corresponding addresses;

    means for generating a control signal for read out of said memory elements from said memory circuit signals in direct response to the scanning of said target screen to indicate which portion of said image data is to be processed;

    and means for controlling the supply of the image data from the television camera to said processor in response to said control signal.
