ABSTRACT:
An apparatus and method for converting images recorded in a plurality of frames in a cinematic film into an output video signal having a plurality of fields. A predetermined number of fields of a video signal are generated from each of the plurality of frames of the film such that the predetermined number of fields generated from odd numbered frames differ from the predetermined number of fields generated from even numbered frames by a number n, where n is a positive integer. An interpolated video signal is generated from a plurality of the generated fields of the video signal which include fields generated from at least two essential frames. The interpolated video signal has a duration of n multiplied by the duration of a field. The interpolated video signal is combined with at least some of the predetermined number of fields of the video signal to form the output video signal.
