A method and apparatus are provided for converting an interlaced video signal to a non-interlaced video signal. For each pixel in each missing line of a video field in a video signal, correlation data is derived for each of the set of possible interpolations to be used in reconstructing the pixel in the missing line. A correlation corresponding to the interpolation scheme likely to give the best results for the missing pixel is selected and an interpolation scheme selected in dependence on this. The pixel in the missing line is then interpolated. The correlation data used in the selection of interpolation schemes is derived from data in the same field as the pixel to be reconstructed and from temporally spaced fields.

Abstract
A method and apparatus are provided for converting an interlaced video signal to a non-interlaced video signal. For each pixel in each missing line of a video field in a video signal, correlation data is derived for each of the set of possible interpolations to be used in reconstructing the pixel in the missing line. A correlation corresponding to the interpolation scheme likely to give the best results for the missing pixel is selected and an interpolation scheme selected in dependence on this. The pixel in the missing line is then interpolated. The correlation data used in the selection of interpolation schemes is derived from data in the same field as the pixel to be reconstructed and from temporally spaced fields.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
