Abstract: An improved circuit for compensating a pattern recognition type edge for a video signal processor which is capable of preventing a undershooting and an overshooting by recognizing a pattern of a luminance signal which is converted into a digital form when compensating an edge of a luminance signal, by substituting a sample value at incline start or end portions and at decline start or end portions of a pattern with the previous sample value or the next sample value, by generating a plurality of luminance signals having a different delay time by sequentially delaying a luminance signal which is converted into a digital form as many as the number of samples, by subtracting a luminance signal which is delayed by the previous process from the luminance signal which is delayed by each process, by recognizing a pattern of an edge of luminance signal by logically operating a difference signal and a reference signal after computing a plurality of difference signals, and by selecting a signal among luminance signals h
