ABSTRACT:
An output video signal is derived from an input video signal by writing the input video signal into a frame buffer, generating a sequence of address words, modifying the sequence of address words, and using the modified sequence of address words to read the video signal from the frame buffer. The sequence of address words is modified by comparing each address word of the sequence with a reference word that defines a predetermined location of the scene represented by the input video signal, and combining each address word that defines a location of the input scene having a selected spatial relationship with the predetermined location with an offset word.
