CONVERSION OF VIDEO DATA FROM INTERLACED TO NON-INTERLACED FORMAT

摘要

A method and apparatus are provided for converting an interlaced video signal to a progressive scan video signal. For each pixel in each missing line of a video field in a video signal to be converted correlation data is provided for each of a set of possible interpolations between adjacent pixels to be used in the constructing missing pixel. A confidence measure is derived in dependence on the number of maxima and minima in the correlation data. The confidence measure most likely to produce an accurate missing pixel is then determined from the confidence measure and a missing pixel interpolator.
