Title: Toshio Hisamura: Innovator in Exposure Devices and Image Formation Systems

Introduction

Toshio Hisamura is a prominent inventor based in Ebina, Japan. He has made significant contributions to the field of imaging technology, holding a total of 7 patents. His work primarily focuses on exposure devices and image formation systems, showcasing his expertise and innovative spirit.

Latest Patents

Hisamura's latest patents include an exposure device, an image forming apparatus, an exposure control method, and a computer-readable medium. The exposure device features a plurality of light-emitting elements, a lighting driver, a first storage, a reader, a shading correction unit, and a second storage. The lighting driver is responsible for driving and lighting up the light-emitting elements based on image data. The first storage holds light amount unevenness correction values for each light-emitting element, while the reader retrieves these values. The shading correction unit executes shading correction based on the values read by the reader. The second storage then retains the correction values obtained from the shading correction process. Ultimately, the lighting driver controls the light power of the light-emitting elements based on the correction values stored in the second storage.

Additionally, Hisamura has developed an image formation system that adds pattern information to print images based on read pattern information from the surface of a medium. This system includes a medium-pattern-information-read unit that reads the pattern information, a pattern-information-image-creation unit that generates a pattern information image, and a print unit that integrates the pattern information image into the print image before printing it on the medium.
