Abstract:
1. An adaptive de-interlacer converting an interlaced video signal into a progressive video signal, comprising: a motion detector generating an alpha value for each interpolated pixel in a current field of the interlaced video signal based on successive fields of the interlaced video signal; an intra-field interpolator outputting an intra-field interpolated pixel based on the current field; an inter-field interpolator outputting an inter-field interpolated pixel based on the successive fields; a motion aliasing artifact detector detecting whether the interpolated pixel is located in a motion aliasing area; and a blending unit receiving and mixing the intra-field interpolated pixel and inter-field interpolated pixel based on the alpha value from the motion detector and the detection result from the motion aliasing artifact detector so as to determine the interpolated pixel.
