Title: Mitsugu Hanabusa: Innovator in Signal Processing and Image Reading Technology

Introduction

Mitsugu Hanabusa is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the fields of signal processing and image reading technology. With a total of 8 patents to his name, Hanabusa's work has had a substantial impact on the industry.

Latest Patents

Hanabusa's latest patents include a signal processing method, signal processing apparatus, and image reading apparatus. His innovative approach involves processing a visible light image signal and an infrared image signal obtained by illuminating a transparent document with light beams from both a visible light lamp and an infrared lamp. This method generates a histogram based on the infrared image signal, calculates a threshold value, and extracts infrared image signal components that are equal to or smaller than the threshold value. The corresponding visible light image signal components are then interpolated using surrounding visible light image signal components.

Another notable invention is an image reading apparatus designed to produce high-quality read images by removing dust or scratches. This apparatus reads image information on a transparent original by synchronously scanning a light source unit and an image reading unit. During the reading process, infrared LED chips on a dust/scratch detection LED substrate and a transparent original illumination lamp are activated to align the LED substrate with the image reading unit. This allows for the acquisition of dust/scratch detection image information, followed by the collection of image information from the transparent original.
