Title: Tsutomu Ikeda: Innovator in Optical Character Recognition

Introduction

Tsutomu Ikeda is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of optical character recognition, holding 2 patents that showcase his innovative approach to technology.

Latest Patents

One of Ikeda's latest patents is an optical character reader that comprises a pre-scanner and a main scanner. The pre-scanner coarsely scans the surface of a postal item and generates video signals representing a postal item pattern. The pattern is divided into a plurality of blocks, with a destination address block being selected for further analysis. The coordinates of the lower side of this block are determined, allowing the main scanner to finely scan a limited area and generate high-resolution video signals. This process enables the detection and recognition of postal codes within the destination address block.

Another significant patent involves a character separating system used for an optical character reader. In this system, a postal code pattern video signal obtained by optically scanning the postal code area is converted into binary data by a quantizing circuit. The video signal is also transformed into multibit pattern data through an A/D converter. The single and multibit pattern data are stored in their respective memories. The character detecting circuit masks the single bit pattern data to set an address corresponding to chained characters, allowing for the separation of these characters at the connecting portions.
