A video signal processing device comprises a synthesizing circuit for synthesizing three signals delayed a unitary time with respect to each other, a detecting circuit for detecting correlations of these three signals, and an output circuit for selecting and outputting, on the basis of a result of detection of the correlations, two signals each indicative of an average value of the signals neighboring in terms of time and a signal which may exist intermediate the length of time. The correlation detecting circuit is operable to detect two of the three signals delayed a predetermined time T from each other, which have a closer correlation with each other. The output signal selecting circuit is operable in response to the result of detection performed by the correlation detecting circuit to output the signal indicative of the average value of these two signals having the closer correlation with each other, or the signal existing at the center of the length of time between these two signals.
