A method for converting an interlaced video signal to a non-interlaced video signal, comprising, for each missing pixel in each missing line of a video field in the interlaced video signal subsequent to a first pixel in the missing line: deriving a correlation data set comprising correlation data for each of a plurality of possible interpolation schemes to be used in reconstructing the missing pixel; dividing each correlation data set into a plurality of correlation data zones (Zone 1, Zone 2, Zone 3); selecting from each correlation data zone (Zone 1, Zone 2, Zone 3) one interpolation scheme (302, 304, 306) among the plurality of possible interpolation schemes: i. for which groups of one or more pixels are more correlated than groups of one or more pixels in all other interpolation schemes in that correlation data zone; and/or ii. by identifying at least one interpolation scheme of the plurality of interpolation schemes for which groups of one or more pixels are more correlated than for groups of one or more pixels in neighbouring interpolation schemes in that correlation data zone, and selecting from the identified at least one interpolation scheme the interpolation scheme for which the groups of one or more pixels are the most correlated; reconstructing the missing pixel using a blend of the selected interpolation schemes (302, 304, 306), wherein the blend is determined based on: the result of comparing (310, 312, 314) the correlation data for the selected interpolation schemes with one another and blending factors for the selected interpolation schemes, the blending factors being based on blending factors used for a spatially preceding pixel in the missing line (316, 318, 320). deriving a correlation data set comprising correlation data for each of a plurality of possible interpolation schemes to be used in reconstructing the missing pixel; dividing each correlation data set into a plurality of correlation data zones (Zone 1, Zone 2, Zone 3); selecting from each correlation data zone (Zone 1, Zone 2, Zone 3) one interpolation scheme (302, 304, 306) among the plurality of possible interpolation schemes: i. for which groups of one or more pixels are more correlated than groups of one or more pixels in all other interpolation schemes in that correlation data zone; and/or ii. by identifying at least one interpolation scheme of the plurality of interpolation schemes for which groups of one or more pixels are more correlated than for groups of one or more pixels in neighbouring interpolation schemes in that correlation data zone, and selecting from the identified at least one interpolation scheme the interpolation scheme for which the groups of one or more pixels are the most correlated; i. for which groups of one or more pixels are more correlated than groups of one or more pixels in all other interpolation schemes in that correlation data zone; and/or ii. by identifying at least one interpolation scheme of the plurality of interpolation schemes for which groups of one or more pixels are more correlated than for groups of one or more pixels in neighbouring interpolation schemes in that correlation data zone, and selecting from the identified at least one interpolation scheme the interpolation scheme for which the groups of one or more pixels are the most correlated; reconstructing the missing pixel using a blend of the selected interpolation schemes (302, 304, 306), wherein the blend is determined based on: the result of comparing (310, 312, 314) the correlation data for the selected interpolation schemes with one another and blending factors for the selected interpolation schemes, the blending factors being based on blending factors used for a spatially preceding pixel in the missing line (316, 318, 320). the result of comparing (310, 312, 314) the correlation data for the selected interpolation schemes with one another and blending factors for the selected interpolation schemes, the blending factors being based on blending factors used for a spatially preceding pixel in the missing line (316, 318, 320).
