A method and apparatus for selectively reproducing and outputting one or several desired fields when effectuating image reproduction at a 2.5-time high speed from a VTR tape that records thereon images of 60 frames/second as converted by the 2-3 pull-down scheme from 24 fields/second images. This apparatus at least includes a frame change detector unit which detects a frame change of the 2-3 pull-down scheme from the significance of a change in luminance level and/or chromaticity level between a reproduced image and its one-field preceding image, a reference field detector unit for detecting, based on a detection span of the frame change detected by the frame change detector unit, a correspondence relation of recording tracks on the VTR tape versus a repeat period or cycle of 2 fields and 3 fields in the 2-3 pull-down scheme, and a storage unit for storing therein the resultant correspondence relation as detected by the reference field detector unit.
