ABSTRACT:
A contour map signal generator is provided for generating television signal. The contour map signal generator consists of n-series connected circuit, each generating signals for a first pattern and second pattern enlarged or reduced from the first and outputting by arithmetic addition contour map data representative of a step region consisting of two patterns. n-step contour map data generated through the n-series circuit is stored in an image memory and read out to be fed back to the input of said contour map signal generator. n x N-step contour map is generated through N times feedback operations. The contour map data is used for generating a television signal representative of a picture effect in which the original pattern area is enlarged or reduced as the time elapses for highlighting the original pattern.
