A UNIT FOR AND METHOD OF IMAGE CONVERSION

摘要

An image conversion unit (200) for converting a first image with a first resolution into a second image with a second resolution being higher than the first resolution, comprises a filter (112) to provide filtered pixel values of the first image to a coefficient-calculating means (106) for calculating a first filter coefficient on basis of the filtered pixel values. The coefficient-calculating means (106) is arranged to control an adaptive filtering means (104) for calculating a second pixel value of the second image on basis of a first pixel value of the first image and the first filter coefficient.
