PURPOSE: To provide a video special effect device small in the circuit scale of a filter circuit fur reducing foldover distortion in the case of performing reduction and improving picture quality.

CONSTITUTION: Two line sequential scanning conversion circuits are provided. A filter processing by a filter processing circuit is performed to line sequential scanning video signals outputted from a first line sequential scanning conversion circuit 103 and interlaced scanning signals are outputted. The interlaced scanning signals after the filter processing are converted into the line sequential scanning video signals by a second line sequential scanning conversion circuit 113 and stored in a frame memory 8.
