The device generates correct outline compensation signal by eliminating the base noise which is superimposed on the outline compensation signal. The device comprises: the first and the second delay unit(11)(12) which delays the input signal for a fixed time; an adder(13) which sums the output of the second delay unit and the input signal(IN); an input unit(18) which generates the positive/ negative outline signal corrupted with noises; negative/positive pulse generator (19)(20) which produces the negative/positive pulse respectively after eliminating the base noise; and an adder(21) which sums the negative and positive pulse signal to produce the outline compensation signal.
