Filed: 2002-08-05
Abstract: PROBLEM TO BE SOLVED: To provide an image processing apparatus that can effectively compress a multi-value image to which limited gradation is scheduled in a small- scale and simple configuration. SOLUTION: An image input section 10 receives multi-value image input data 110 whose binary processing is scheduled. A threshold value reference section 20 gives a threshold value corresponding to a target pixel of the input image data 110 from a threshold value matrix used by binary processing performed at a post-stage to a pixel value revision section 30 as threshold value data 120. The pixel value revision section 30 revises a target pixel value of the input image data 110 by a predetermined method on the basis of the threshold value data 120 and gives the result to an image output section 40 as revised image data 130. The image output section 40 applies output processing to the revised image data 130 externally. The pixel value revision section 30 revises an original pixel value so as to provide convenience to the encoding at the post stage within a range not bridged over the threshold value level. The encoding efficiency can be enhanced without providing adverse effect to the binary processing at the post stage.

Abstract: <P>PROBLEM TO BE SOLVED: To provide a printer in which print efficiency is enhanced by reducing the memory resource and the processing time required for print masking.  <P>SOLUTION: Computation and data-storage are minimized in both accounting for element condition and reallocation of print tasks away from subnominal elements.

A reallocation distributes print burden from a subnominal element to plural other elements without making a new mask. Rather, entries for a poor element in a current mask are shifted prospectively and quickly to other elements serving the same pixel rows.  <P>COPYRIGHT: (C)2003,JPO
