ABSTRACT:
A frame-frequency converting apparatus acts on an input video signal resulting from 2-3 conversion of original picture information. Fields represented by the input video signal are rearranged, and thereby the input video signal is converted into a rearrangement-resultant video signal. Every pair of an odd field and a subsequent even field represented by the rearrangement-resultant video signal originate from a same frame represented by the original picture information. The rearrangement-resultant video signal is processed into a combination-resultant video signal, and specifically every pair of an odd field and a subsequent even field represented by the rearrangement-resultant video signal are combined into a frame represented by the combination-resultant video signal. Frames represented by the combination-resultant video signal are thinned out, and thereby the combination-resultant video signal is converted into a conversion-resultant video signal which has a predetermined frame frequency.
