Abstract: A motion amount at a pixel position to be interpolated of a field of interest is calculated. A difference coefficient between frames is calculated based on video signals of two fields which are adjacent to the field of interest and are separated by one frame. A motion intensity between fields is calculated based on video signals of the field of interest and a field after the field of interest. The motion amount is corrected using a predetermined function. The corrected motion amount is corrected again based on the difference coefficient and motion intensity.

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.
