Abstract
A method and apparatus are provided for displaying a progressive scan television signal derived from interlaced fields of a television signal. A colour space vector is derived for a current pixel and for each of at least two adjacent pixels within at least one field. A difference value between the current pixel colour space vector and each of the at least two adjacent pixel colour space vectors is then derived and used to determine whether motion is present at the current pixel. An appropriate method to derive the progressive scan image is then selected in dependence on the result of the determination.
