Abstract
A time compressed color difference signal included in a high definition television signal is roughly compensated for its units of an interval of one-half of a transmission sampling interval in a range obtained by multiplying the amount of a horizontal motion vector by a compression rate. In addition, the time compressed color difference signal roughly compensated for its finely compensated for in a horizontal direction in units of an interval of one-half of the transmission sampling interval or less by a one-dimensional or two-demensional spacial filter. Futhermore, the time compressed color difference signal is compensaed for in a vertical direction by a distance corresponding to the amount of a vertical motion vector. On this occasion, a time compressed color difference signal to be inserted into a position to be interpolated in the present frame is produced using a time compressed color difference signal in a position spaced apart from the position to be interpolated by a distance corresponding to the amount of the vertical motion vector such that the time compressed color difference signal to be inserted becomes the same type of color difference signal as other time compressed color difference signals on a line to which the position to be interpolated belongs.
