ABSTRACT:
The present invention enables highly accurate estimation of a motion amount of a target pixel for motion-estimation located between two adjacent lines in a current field when generating a non-interlaced video signal from an interlaced video signal. To achieve this aim, an inter-field motion-estimating unit estimates a motion amount between a current field and a previous field. An intra-field motion-estimating unit estimates a motion amount within a current field. A motion amount calculation unit calculates a final motion amount based on the inter-field motion amount estimated by the inter-field motion-estimating unit and the intra-field motion amount estimated by the intra-field motion-estimating unit, and then outputs the motion amount.
