ABSTRACT:
A method and an apparatus are provided for converting an interlaced video signal to a progressive scan signal. For each pixel in each missing line of a video field in a video signal to be converted, correlation data is derived for each of a set of possible interpolations between adjacent pixels to be used in reconstructing a missing pixel.A confidence measure is derived from the correlation data and adjustment data for correlation data is selected. The correlation data is then adjusted with the adjustment data, and on the resultant data a determination is made as to which interpolation scheme is most likely to produce an accurate missing pixel. The missing pixel is then interpolated using the selected interpolation scheme.
