A UNIT FOR AND METHOD OF IMAGE CONVERSION

摘要

An image conversion unit (200) for converting a first input image with a first resolution into an output image with a second resolution, comprises a coefficient-determining means (106) for determining a first filter coefficient on basis of pixel values of the first input image. The coefficient-determining means (106) is arranged to control an adaptive filtering means (104) for calculating a pixel value of the output image on basis of an input pixel value of the first image and the first filter coefficient. The adaptive filtering means (104) is arranged to perform a non-linear operation.
