Title: Hirokazu Ogura: Innovator in Image Data Compression
Introduction
Hirokazu Ogura is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of image data compression, particularly in the realm of moving picture telecommunication. His innovative work has led to the development of a patented method that enhances the performance of image decoding processes.
Latest Patents
Hirokazu Ogura holds a patent for an "Image data binary coding method and apparatus." This invention focuses on a method and device for decoding received coded image data, which is essential for image compression in moving picture telecommunication. The process involves discrete cosine transformed coded compression to improve decoding performance. The invention scans positional information within an image block using a run/level dividing device, which processes run values from the received data. The pairs of run and level values undergo a reverse quantifying process to create corresponding position and level values. The level values are then transformed into positional information through a zigzag scan, followed by reverse quantification. Finally, a reverse discrete cosine transforming device decodes the image data from the reverse quantified data.
