Abstract
A method and apparatus for inverse dithering a dithered image is disclosed. The system includes a plurality of digital filters which are organized according to a preselected order. A selection module enables the selection of one filter from the plurality of filters according to the preselected order to filter a presently selected portion of the dithered image. The selected portion of the dithered image is then processed based upon the selected filter to generate a portion of the inverse dithered image.
