Title: Ikuo Noguchi: Innovator in Stencil Making and Image Processing

Introduction

Ikuo Noguchi is a notable inventor based in Ibaraki-ken, Japan. He has made significant contributions to the fields of stencil making and image processing. With a total of 2 patents, his work showcases innovative approaches to technology.

Latest Patents

One of Noguchi's latest patents is a stencil making apparatus. This apparatus thermo-sensitively perforates a stencil sheet using a thermal print head. It includes a controlling device that drives contiguous N pieces of heat-generating elements of the thermal print head while shifting the heat-generating timings at every 1/N of a period of one line of main scanning. This method allows for precise perforation of inputted image data.

Another significant patent is a method of and apparatus for processing an image. This method utilizes an error diffusion technique that propagates density distribution errors in pixels surrounding a pixel of interest. The process involves calculating thresholds of densities based on the area ratio between pixels, selecting a pixel to be noted, and calculating errors produced in peripheral pixels. The method ultimately aims to rearrange the density of the noted pixel and compare it with thresholds to obtain a corresponding binary level.
