装置。[Claims for Utility Model Registration] A filter that separates a carrier color signal from a composite video signal, a delay line that delays the separated carrier color signal by 1H, and a carrier color signal delayed by 1H by the delay line and a carrier color that is not delayed. a subtracter that calculates a difference between signals; a first switch that controls conduction of either one of the input signals to the subtracter; and a first switch that doubles or doubles the level of the output signal from the subtracter.
A television signal processing device comprising: a level adjuster that adjusts to 1/2; and a second switch that outputs the output signal of the subtracter with or without the level adjuster. .
