Abstract

PURPOSE:To effectively detect and remove a chroma dot interference and to improve a picture quality after a separation, by executing the luminance and chrominance separation of a video signal by the use of a separating means consisting of a comb-line filter and a separating means except it and selecting a signal by one separating means according to the state of the video signal. CONSTITUTION:The titled processor is provided with the first separating means 1, 2, 3, 4, 5 for separating the luminance signal and the chrominance signal from the video signal by the comb-line filter, the second separating means 2, 6 for separating the luminance signal and the chrominance signal from the video signal without using the comb-line filter and selecting means 17, 7, 8 for selecting the luminance signal and the chrominance signal from either one of the first separating means and the second separating means based on a detecting result after the state of the video signal is detected. Thereby, according to the state of the video signal, the luminance signal and the chrominance signal can be separated adaptively.
