Title: Information processing method
Inventor: WATANABE TAKASHI
IPC: G06F7/72
Filed: 2002-02-22
Abstract: <P>PROBLEM TO BE SOLVED: To detect an erroneous operation in an information processor.  <P>SOLUTION: An adder in the present invention is obtained by adding an embedding part for embedding an erroneous operation detecting code to input data, an erroneous operation detecting code inspecting part for inspecting an arithmetic result, and an erroneous operation detecting code erasing part for removing the erroneous operation detecting code, to a normal adder. First, erroneous operation detecting data D is generated and multiplied by A and B. Then AD is added to BD through the use of the normal adder. AD+BD =(A+B)*D=CD. The erroneous operation detecting code inspecting part calculates a residual with D as a modulus concerning the arithmetic result, and confirms that the result is zero. When the formula: CD mod D≠0 is obtained, an error signal is outputted. The original arithmetic result is obtained as a formula: CD*1/D=C by multiplying the arithmetic result by 1/D in the erroneous operation detecting code erasing part.  <P>COPYRIGHT: (C)2003,JPO

Title: De-screening of halftone using sigma filter
Inventor: KUO CHUNGKUI
IPC: H04N1/40
Filed: 2002-02-25
Abstract: PROBLEM TO BE SOLVED: To provide an improved system and method for substantially de- screening any type of color image. SOLUTION: A color image is de-screened by using two-stage sigma filters. The two-stage sigma filters can be used for converting a color halftone image into a continuous tone image regardless of used screening process. The two-stage sigma filters are constituted by using an O (N) algorithm for executing smoothing, and for simultaneously preserving edge information in red/green/ blur(RGB) color spaces. This system and method is able to fulfill double standards for completely removing halftone screen while preserving edge information so that higher performance can be expected than a conventional method using, for example, Gauss blur. When this system and method is combined with a halftone segmentation technology, a complete document processing algorithm for a variable density and color document is generated.
