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 a set of possible interpolations to be used in reconstructing pixels in each missing line (12). A correlation is selected (14) corresponding to the interpolation scheme likely to give the best result for a missing pixel, and an interpolation scheme selected (16) in dependence on the selected correlation. The pixel in the missing line is then interpolated (18). The step of deriving correlation data uses both the field containing the missing line and adjacent 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 a set of possible interpolations to be used in reconstructing pixels in each missing line (12). A correlation is selected (14) corresponding to the interpolation scheme likely to give the best result for a missing pixel, and an interpolation scheme selected (16) in dependence on the selected correlation. The pixel in the missing line is then interpolated (18). The step of deriving correlation data uses both the field containing the missing line and adjacent fields.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
