A progressive scanning conversion apparatus for converting an interlaced scan video signal into a progressive scan video signal by performing interpolation based on original pixels which are obtained in a matrix by sampling the interlaced scan video signal in a current field, original pixels which are obtained in a matrix by sampling the interlaced scan video signal in a previous field which is immediately prior to the current field, and original pixels which are obtained in a matrix by sampling the interlaced scan video signal in a next field which is immediately following the current field. The apparatus includes a motion vector detector for detecting a motion vector between two of the current field, the previous field, and the next field; a motion estimation circuit for estimating a pixel value in the current field, from one of a pixel in the previous field and a pixel in the next field using the motion vector detected by the vector detection means; and an interpolated pixel generator for generating an interpolated pixel used for conversion by multiplying the pixel value obtained by the motion estimation means and the corresponding pixel value in the current field by a weighting factor and summating the multiplication results.
