摘要
A method for inverse dithering a dithered image using a filter selected from a set of filters arranged in a preselected order is disclosed. Upon receipt of a selected portion of a dithered image, the selected portion is up-multiplied from a first amplitude resolution to a second amplitude resolution. The up-multiplied dithered image at the second amplitude resolution is then filtered by the selected filter coefficients to generate the inverse dithered image.
