Introduction

Yasushi Nagata is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the field of defect detection technology, holding a total of 9 patents. His innovative approaches have enhanced the accuracy and efficiency of inspection processes in various industries.

Latest Patents

Nagata's latest patents include a defect detection device, defect detection method, and program. This technology involves acquiring a plurality of captured images while changing the light illumination state. Each captured image is compared with a corresponding reference image to identify regions where the captured image is darker than the reference image, marking them as dark defect candidate regions. Additionally, regions where the captured image is lighter than the reference image are identified as lightness/darkness inverted regions. By excluding dark defect candidate regions that overlap with lightness/darkness inverted regions based on a prescribed criterion, the system effectively reduces the over-detection of defects caused by grime during external appearance inspections. Another notable patent involves an inspection apparatus and method that utilizes two imaging units to inspect different regions of an object's surface, ensuring precise evaluations of mirror finish treatments.
