PURPOSE: To suppress flickers at the time of the variable speed reproduction of a digital VTR or the like by changing a coefficient corresponding to the output field order of a video signal converter by a vertical filtering device. CONSTITUTION: A deblocking/deshuffling circuit 16 deblocks and deshuffles the inputted video signals of a frame unit, converts them into the video signals of a field unit and outputs them. At the time, a microcomputer 31 sends control signals VFF and VFS for setting a field order corresponding to the reproduction mode (normal, slow and reverse, etc.,) of the digital VTR to the deblocking/ deshuffling circuit 16. The output of the deblocking/deshuffling circuit 16 is filtered corresponding to the field order by a vertical filter 32 for which the coefficient is changed by the control signals from the microcomputer 31.
