Title: Eisaku Tomita: Innovator in Image Data Compression

Introduction

Eisaku Tomita is a notable inventor based in Itami, Japan. He has made significant contributions to the field of image data processing, holding a total of 3 patents. His work focuses on enhancing the efficiency of image data compression and expansion circuits.

Latest Patents

One of his latest patents involves an image data compression-expansion circuit. This innovation features a line buffer device that temporarily stores a predetermined area of original image data. The data is divided into small blocks, each having a small area, allowing for the encoding of image data for each block into data with a fixed length by a compression processor. The line buffer device consists of a first-stage line buffer group and a second-stage line buffer group. Notably, the number of line buffers in the first-stage group is smaller by one than the number of lines constituting one block, while the second-stage group has the same number of line buffers as the number of lines in a block. This design significantly shortens encoding processing time and simplifies the circuit structure.
