Kazuhiro Shimakawa

Title: Kazuhiro Shimakawa: Innovator in Graphic Processing Technology

Introduction

Kazuhiro Shimakawa is a notable inventor based in Hyogo, Japan. He has made significant contributions to the field of graphic processing technology, holding a total of 5 patents. His work focuses on enhancing the efficiency and performance of graphic accelerators and rendering systems.

Latest Patents

One of his latest patents is a graphic accelerator with an interpolate function. This innovative graphic accelerator includes an image-forming data decode unit, an image memory control unit, and a screen data generation unit. The image memory control unit manages the writing of output from the image-forming data decode unit to a frame buffer and retrieves information stored in the frame buffer. The screen data generation unit restores color information based on the data read from the frame buffer and generates screen data. Notably, the frame buffer stores pixel information in a deleted form, which includes two types of color information out of the three (R, G, and B). During reading, the deleted color information is interpolated with the color information of other pixels.

Another significant patent is a rendering processing apparatus that requires less storage capacity for memory. In this rendering processing system, a rendering memory stores pixel data generated by a rendering operation circuit, while a display memory holds the image data of the current frame read from the rendering memory. The display memory only stores pixel data read from the rendering memory with certain prescribed information excluded, thereby decreasing the storage capacity needed and reducing the time required for writing data into the display memory.
