Title: Hiromitsu Kawajiri: Innovator in Character Recognition Technology

Introduction

Hiromitsu Kawajiri is a notable inventor based in Gifu-ken, Japan. He has made significant contributions to the field of character recognition technology, holding a total of 2 patents. His work focuses on improving the accuracy and efficiency of recognizing characters, particularly in handwritten formats.

Latest Patents

Kawajiri's latest patents include a "Method and apparatus for pre-recognition character processing." This invention involves an apparatus that recognizes characters read by a reading unit. It forms a circumscribing rectangle around a read character and assesses the degree of narrowness of that rectangle. Characters that meet a predetermined narrowness threshold are selected, and blank areas are added to correct the character area for better recognition. This method allows for the normalization of characters that are significantly elongated, facilitating easier recognition and grouping of character patterns.

Another significant patent is the "Hand-written character recognition apparatus and facsimile apparatus." This apparatus utilizes a Contact Image Sensor (CIS) to read image data of handwritten characters. The data is stored in a bit-mapped line buffer, and a histogram is produced to evaluate the rough position and width of each character. This innovative approach enhances the accuracy of recognizing handwritten characters by effectively identifying spaces between them.

Career Highlights

Throughout his career, Kawajiri has worked with prominent companies such as Sanyo Electric Co., Ltd. and Tottori Sanyo Electric Co., Ltd. His experience in these organizations has contributed to his expertise in character recognition technologies.
