Abstract
A frame memory stores one-frame data of an input digital video signal and outputs the stored data as a one-frame delayed digital video signal. A first motion data generator receives the input digital video signal and the one-frame delayed digital signal from the frame memory and generates first motion data in accordance with the difference between these two signals. A data compander receives the one-frame delayed digital video signal from the frame memory, compands the data amount of the one-frame delayed digital video signal, and oututs the resultant signal. A sub-frame memory stores the output signa from the data compander and outputs the stored data as a two-frame delayed signal. A data expander receives the two-frame delayed output signal from the sub-frame memory, expands the two-frame delayed output signal to the original data amount, and outputs the resultant signal. A second motion data generator receives the input digital video signal and the two-frame delayed signal from the data expander, and generates second motion data in accordance with the difference between the two signals.
