Title: The Innovations of Shinobu Satonaka

Introduction

Shinobu Satonaka is a notable inventor based in Toyonaka, Japan. He has made significant contributions to the field of image processing technology, holding a total of 10 patents. His work has advanced the capabilities of image reading devices and processing apparatuses, showcasing his expertise and innovative spirit.

Latest Patents

One of his latest patents is an image reading device and image forming apparatus. This device includes an image sensor that optically reads a document and outputs an electric signal. It features a period control circuit that manages the horizontal synchronizing signal's period, allowing for adjustments in the charge storage time within the image sensor. Additionally, a scanning speed control circuit is incorporated to ensure the document's scanning speed aligns with the horizontal synchronizing signal's period, which can be variably set according to the image reading mode.

Another significant patent is an image processing apparatus. This apparatus allows for the relative movement of a document on a support table and an optical system for scanning. It reads the document's image as a density signal, which is then processed as needed. The apparatus includes a document mat that, when placed on the support table, enables the read signal to represent an intermediate color. A discriminating device assesses whether the density signal indicates this intermediate color, producing a binary signal. Furthermore, it features a memory with a capacity based on the density signal, along with a write control that synchronizes the binary signal's writing with the scanning movement.
