Title: Shin-ichi Imayoshi: Welding Imaging Innovation.
Introduction
Shin-ichi Imayoshi is an inventor associated with Mitsubishi Heavy Industries Limited in Hiroshima, Japan. His patent work includes an imaging device designed to capture clear images of welding processes, where intense arc light and dark areas can appear in the same scene.
Latest Patents
Imayoshi is credited with 1 patent: “Imaging Device for Welding.” The invention combines a lens with an optical filter containing a neutral density filter, an ultraviolet cut filter, and a green band-pass filter. A CMOS imaging unit with a wide dynamic range detects the filtered light, while video signal processing with automatic gain control and a digital signal processor produces an image signal spanning low-intensity dark regions to high-intensity arc light. The signal can then be sent to a display unit.
Career Highlights
The patent reflects Imayoshi’s work on imaging technology for welding applications. By addressing the contrast between dim surroundings and bright welding arcs, the device is designed to make welding scenes more visible on a display.
Collaborations
Imayoshi’s listed coworkers include Hiroshi Yatabe and Motohiro Itotani. His patent is associated with Mitsubishi Heavy Industries Limited.
Conclusion
Shin-ichi Imayoshi’s welding-imaging patent combines optical filtering, wide-dynamic-range sensing, and image processing to address the challenging lighting conditions of welding.
