Title: Toshiro Ishikawa: Innovator in Information Processing

Introduction

Toshiro Ishikawa is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of information processing, holding a total of 2 patents. His work focuses on enhancing image processing techniques, which are crucial in various technological applications.

Latest Patents

Ishikawa's latest patents include an information processing apparatus and method, as well as a program designed to improve image processing. The first patent describes an information processing apparatus that utilizes a first processing unit to define an entirety indicated by multiple pixels as a single image. This unit identifies a first histogram representing the brightness in the image. A second processing unit sets an adjustment amount in the first histogram, while a third processing unit subtracts a portion near the peak of the first histogram based on the adjustment amount. This process generates a second histogram by shifting the histogram corresponding to the portion to an area where the peak is relatively low.

The second patent focuses on an image processing apparatus that stores image data in a current block memory and a search range of a reference picture in a search window memory. Using a gray code, the register file of the search window memory is read, and candidate blocks are successively extracted. The processor elements then find the differences between the current block and candidate blocks, calculate cumulative values, and compare these values to extract the candidate block that yields the smallest value. This process ultimately detects the motion vector based on the selected candidate block.
