PROBLEM TO BE SOLVED: To provide an improved method and apparatus for deriving a progressive scan image from an interlaced image. SOLUTION: In this, for each pixel to be inserted in a field from an interlaced image, a difference value is derived from each pair of a set of symmetrically opposed pixels with respect to the pixel to be reconstructed and from adjacent lines to the pixel to be reconstructed. A determination is made as to which pair of pixels has the lowest difference value associated with it and the average value of this pixel is selected as a value of the pixel to be inserted when this average value falls within a range defined by the value of the pixels directly above and below the pixel to be reconstructed.
