Title: Innovations by Yoji Morishita

Introduction

Yoji Morishita is a notable inventor based in Kariya, Japan. He has made significant contributions to the field of image display technology, holding 2 patents that showcase his innovative approach to data compression and image processing.

Latest Patents

One of his latest patents is an image display system that allows for scrolling images at high speed using data compression. In this invention, when a user pushes a scroll-direction key, an ECU obtains a division map from memory corresponding to the designated direction. The ECU then outputs this division map to a display controller, which compresses it for storage in VRAM. During scrolling, the display controller expands the compressed division map and outputs only the necessary portion to an image signal generator. This process enables the displayed image to scroll at high speed while remaining easily recognizable for the user.

Another significant patent by Morishita is an image data compressing method and apparatus that compresses image data separately by modifying color. This apparatus includes a color selecting unit, a data separating unit, and a data compressing unit. The selecting unit picks an arbitrary color from the original map image, while the separating unit divides the original image data into modified color data and selected position data. The compressing unit then compresses these data separately to enhance data compression efficiency. This method allows for improved image quality by ensuring that background colors can be adjusted to match commonly used colors.
