Title: Yoichi Ogawa: Innovator in Moving Picture Encoding and Digital Communication

Introduction

Yoichi Ogawa is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the fields of moving picture encoding and digital communication. With a total of 2 patents, his work has had a lasting impact on technology.

Latest Patents

Ogawa's latest patents include a moving picture encoding apparatus and a digital cordless telephone system. The moving picture encoding apparatus is designed to divide moving picture data captured by a camera into small blocks. It detects motion vectors corresponding to these blocks and employs encoding means for motion-compensating the small blocks. This process allows for an inter-frame predictive encoding that enhances video quality. Additionally, the apparatus includes means for extracting moving object areas and calculating representative vectors for these areas, ultimately improving the efficiency of video encoding.

The digital cordless telephone system features a controller at the base station that supervises radio communication between the base station and multiple personal stations. Each personal station has preset functions stored in the base station. When a personal station goes off-hook in response to a call, the controller retrieves the function description data and sends it to the call sending station. This system ensures that users receive a complete display of the functions before establishing a connection for a conversation.
