ABSTRACT:
A system for the discontinuous transformation of visual images utilizing a variable delay. The visual image to be transformed is first converted to a time-varying video signal. This signal is then converted to a digital signal which is fed to a delay circuit whose time delay can be instantaneously varied. The exemplary delay circuit shown includes a random access memory which is usedc to store and release the stored digital information as a function of the desired delay. The output of the delay circuit can then be inverted to achieve the transformed visual image.
