Introduction

Nobuyuki Shimizu is a prominent inventor based in Hatsukaichi, Japan. He has made significant contributions to the field of image processing, holding a total of 2 patents. His work focuses on enhancing the efficiency and effectiveness of image processing systems.

Latest Patents

Shimizu's latest patents include an "Image processing system having polygonal line processing of pixel line" and a "Method of recognizing a circular arc segment for an image processing." The first patent describes an image processing device designed to trace a pixel line in pixel line data and provide polygonal line data. This device features a pixel line tracing means that forms tracing dot data by sequentially tracing pixels. It also includes a tracing direction selecting means that determines the direction of tracing based on nearby pixel data at branch points. The polygonal line processing unit then forms polygonal line data by continuing the tracing in a consistent direction over branch points.

The second patent outlines a method for recognizing arcuate or circular arc segments within an image processing apparatus. This method involves selecting arbitrary image structuring points as segmenting end points and extracting the furthest image structuring point from a straight line connecting these points. The method recognizes three consecutive polygonal-line structuring points as an arc segment based on their proximity to a virtual circle, enhancing the accuracy of image processing.
