Title: Shigehisa Kitani: Innovator in Light Communication and Image Processing
Introduction
Shigehisa Kitani is a notable inventor based in Chigasaki, Japan. He has made significant contributions to the fields of light communication and image processing. With a total of 2 patents, his work showcases innovative solutions that enhance technology in everyday applications.
Latest Patents
One of Kitani's latest patents is for light communication equipment. This invention comprises a photo-sensor that senses a modulated light signal, a processor that demodulates the light signal, and a keyboard with multiple keys for processing instructions. The processor is housed within a casing, and the keyboard is attached to this housing. The photo-sensor is designed to have a sensing direction aligned with the keyboard's longitudinal line.
Another significant patent is an image processing system. This system includes an image reader unit that reads images and generates them as 4-bit data. A communication unit then converts this 4-bit data into 6-bit data by adding the upper 2-bit component of the 4-bit data as a lower 2-bit component of the 6-bit data. The resulting 6-bit data is supplied to a binary printer for halftone processing and printing. This system allows for the processing of image signals with different bit numbers, achieving excellent image reproduction with a simple setup.
