Title: Tatsuya Nakajima: Innovator in 3D Image Processing

Introduction

Tatsuya Nakajima is a prominent inventor based in Toyonaka, Japan. He has made significant contributions to the field of 3D image processing, holding a total of 6 patents. His innovative work has advanced the way images are processed and displayed, particularly in the realm of polygon displays and 3D modeling.

Latest Patents

One of Nakajima's latest patents is a method for displaying polygons based on the x coordinates of edges on scan lines. This invention involves processing image data to enable polygons to be displayed on a screen of scanned lines. The method utilizes a first memory to store X and Y coordinate data for edge points of the polygons, while a second memory arranges polygon numbers in a processing order. A series of computing units work together to compute data for the sides of each polygon and to process the start and end point data, ultimately outputting polygon dot data in synchrony with the scan lines.

Another notable patent is a method and device for 3D image processing. This invention presents a coordinate transformation method that allows for the placement of a 3D model in world coordinates and spatially relates the model to a viewpoint. The method includes a contraction process that reduces the size of the 3D model during world coordinate transformation, ensuring that the viewpoint shift is also minimized in accordance with the degree of contraction.
