A noise shaping processing part performs noise shaping processing on pixel data. An adding circuit performs accumulative adding processing on the noise-shaped pixel data. A first bit-shift part performs bit-shift processing on the accumulatively-added and noise-shaped pixel data. A second bit-shift part performs bit-shift processing on unprocessed pixel data. An inter-pixel subtracting circuit calculates a gradation level difference between neighboring current pixel and previous pixel in a horizontal direction in the unprocessed pixel data. A boundary judging circuit judges presence of a boundary between a low-gradation area and a high-gradation area in the horizontal direction of the unprocessed pixel data, based on a comparison between the gradation level difference and a prescribed threshold value. A selecting circuit selects an output of the first bit-shift part when the boundary judging circuit judges there is no boundary, and selects an output of the second bit-shift part when judged there is a boundary.

A method for curvilinearly converting of web or sheet material by compression of the material between an upper table and a lower table. The tables are each connected to a respective supporting structure and operate conjointly on either side of the plane of travel of the material along a longitudinal axis. During the compression phase, there is a phase of essentially unidirectional intentional elastic deformation of a structure of one of the tables. The deformation increases and then decreases as the curvilinear surface of one table rolls past the other table, for providing generally more uniform compression as the surface rolls. An apparatus for the compression includes the structure described.
