ABSTRACT:
Apparatus and method for descreening and for performing resolution changes and correction of misregistration on a color half-tone image in order to produce a color continuous tone image. The apparatus includes filter apparatus for removing screen information from the half-tone image including a plurality of different filters each providing interpolation and screen removal functions and a controller for selecting per pixel of the continuous tone image and in accordance with sensed misregistration and as a function of desired resolution changes, one of the filters for operation on a neighborhood of the pixel.
