Title: Keisuke Oyaizu: Patents in Ophthalmic Imaging and Measurement.

Introduction

Keisuke Oyaizu is an inventor based in Kawasaki, Japan. His patent work includes technologies for ophthalmic imaging and eye measurement. He is associated with Canon Kabushiki Kaisha and is credited with 4 patents.

Latest Patents

Oyaizu’s listed patents address imaging and measurement challenges in eye care.

“Image Processing Apparatus, Control Method Therefor, and Storage Medium Storing Program” describes a system for comparing tomographic images of a subject’s eye captured at different times. When the images cover regions of different sizes, the apparatus displays the corresponding portion of the larger-region image alongside the image covering the smaller region. This approach supports comparison of matching areas across scans.

“Ocular Characteristic Device to Eliminate Ghosting from an IOL During Corneal Curvature Measurement” concerns measurements taken when an intraocular lens (IOL) is present. The disclosed method increases the intensity of visible light projected onto the eye compared with the intensity used when measuring an eye without an IOL, helping address ghosting during corneal-curvature measurement.

Career Highlights

Oyaizu’s listed inventions focus on practical aspects of ophthalmic technology, including longitudinal comparison of eye scans and measurement conditions for eyes with an implanted lens. His work is associated with Canon Kabushiki Kaisha.
