An apparatus and method for converting an image signal for converting a progressive scan image signal having given number of frames per given time into an interlaced scan image signal having different number of frames per the given time from the progressive scan image signal, the converting method involving separating fields from each frame of the progressive scan image signal and storing the fields; comparing each of the stored fields and detecting whether a picture switch occurs between the frames of the progressive scan image signal based on whether there is a movement between the compared fields; and controlling the number of the fields extracted per frame from two sequential frames in which the picture switch occurs, whereby the fields separated from each of the two sequential frames form each of the different frames of the interlaced scan image signal.
