Abstract

PURPOSE:To decrease dot disturbance or cross color disturbance by employing a method in which the frequency band limitation as to the time base is executed by means of an output from a moving detection circuit or a method in which said limitation is executed in the horizontal and the vertical directions. CONSTITUTION:A first and a second color separation means 10A, 10B are provided and either of the chrominance signals extracted and separated by the means 10A, 10B are selected by using a signal obtained from the moving detection means 20 that decides the correlation in the time-base direction between composite color video signals. The first color separation means 10A, separates the chrominance signal from a composite color video signal by using the inter- frame correction, while the second color separation means 10B separated the chrominance signal from the composite color video signal by using the correlation in the horizontal direction and the vertical direction in a field.
