Title: Innovations by Hirofumi Saitoh
Introduction
Hirofumi Saitoh is a notable inventor based in Ogaki, Japan. He has made significant contributions to the field of biometric information processing and digital data coincidence determination. With a total of 2 patents, Saitoh's work showcases his expertise and innovative spirit.
Latest Patents
Saitoh's latest patents include a biometric information processing apparatus and a biometric information processing method. The biometric information processing apparatus aims to acquire a suitable fingerprint image by correcting an elongated fingerprint image. A line sensor captures the fingerprint image as multiple line-shaped images. A computation unit then computes a similarity value using an evaluation function to assess the degree of similarity between the line-shaped images. When the similarity value meets a predetermined threshold, a compression unit compresses the relevant line-shaped images to generate a new line-shaped image. Ultimately, a generation unit combines this new image with other line-shaped images to create the complete fingerprint image.
His second patent, the digital data coincidence determining circuit, is designed to determine whether two sets of digital data coincide. This circuit includes a wiring and several bit comparison circuits, each corresponding to the bits of the digital data. Each bit comparison circuit consists of transistors that work together to suppress an increase in circuit area while effectively comparing the logical signals of the digital data.
