Title: Koichi Yamashita: Innovator in Infrared Imaging Technology
Introduction
Koichi Yamashita, an accomplished inventor based in Tokyo, Japan, holds an impressive portfolio of 36 patents. His work primarily focuses on enhancing infrared imaging technologies, contributing significantly to advancements in this field.
Latest Patents
Among his latest innovations are the "Infrared Imaging Device" and "Non-Transitory Computer-Readable Storage Medium." The infrared imaging device is designed to reduce streak noise by calculating correction coefficients from a single image. This device includes a thermal image generator that produces a thermal image based on signals from a thermal image sensor. The correction coefficient calculator calculates multiple coefficients that convert pixel values to target values, effectively reducing streak noise. Additionally, the thermal image corrector refines the generated thermal image using these coefficients.
Another notable patent pertains to an image processing device and thermal image generation system. This system features a background image generator that stores a skeleton image derived from various thermal images taken in the same field of view. The average image produced from these thermal images is sharpened, and then the system uses this skeleton image to correct new thermal images, resulting in high-quality thermal images with a substantial signal-to-noise ratio.
