Title: Norishige Tsukada: Innovator in Halftone Image Generation

Introduction

Norishige Tsukada is a notable inventor based in Matsudo, Japan. He has made significant contributions to the field of image processing, particularly in the generation of screened halftone images. His innovative approach has led to the development of a unique method and apparatus that enhances the quality and reproducibility of halftone images.

Latest Patents

Tsukada holds a patent for a "Method and apparatus for generating screened halftone images." This invention includes a system for assuming an area of halftone dots with desired periodicity and tone reproducibility. The method subdivides the area into minute cells and sets address values (X, Y) for each cell. It computes a threshold value of density for each cell as a function of the relevant address values and uses this computed value as the threshold for density. Additionally, the apparatus obtains a density-related video signal by scanning the original image and produces halftone dot signals by comparing the video signals with the threshold value of density.
