Title: Humikazu Nagano: Innovator in Optical Reader Technology

Introduction

Humikazu Nagano is a prominent inventor based in Nara, Japan. He has made significant contributions to the field of optical reading systems, holding a total of 5 patents. His innovative work has advanced the technology used in various imaging applications.

Latest Patents

One of Nagano's latest patents is focused on read-out level compensation in an optical reader system. This invention includes a plurality of sensor elements that provide a picture signal. Before initiating an actual reading operation, a white background plate is scanned to obtain reference information. The data from the white background plate is reversed to obtain a reciprocal of the white level, which is then memorized in a memory. During the actual reading operation, the picture signal derived from the sensor elements is multiplied by the reciprocal stored in memory to compensate for the nonuniformity of the sensor outputs. Another notable patent is for an output correcting system for facsimile. This optical image reading apparatus comprises a solid-state image sensor with multiple blocks, generating video signals corresponding to the object being read. It includes means for determining mean values of the video signals, storing these mean values in digital form, and converting the digital information to analog information for corrected output.
