Title: Iwao Hidaka: Innovator in Digital Video Processing

Introduction

Iwao Hidaka is a notable inventor based in Higashiosaka, Japan. He has made significant contributions to the field of digital video processing, holding a total of 3 patents. His work has advanced the technology used in video signal processing, making it more efficient and effective.

Latest Patents

Hidaka's latest patents include a digital processing apparatus that utilizes two synchronization signals. This apparatus features a high-speed response phase-locked loop (PLL) that generates a first clock signal synchronized with the horizontal synchronization signal of the input video. An analog to digital converter then digitizes the video signal based on this clock signal. Additionally, a write controller manages a video memory to store the digitized signal, while a low-speed response PLL produces a second clock signal based on the vertical synchronization signal. This innovative design allows for stable storage and retrieval of digitized video signals, enhancing the processing capabilities of video data.

Another significant patent is the orthogonal transform apparatus for video signal processing. This invention executes algorithms for orthogonal transform operations, such as the 8-point fast cosine transform. By utilizing a single multiplier capable of performing multiplication operations within one sample period, the apparatus reduces the hardware scale compared to systems using multiple separate multipliers. This efficiency is achieved through time division multiplexing, allowing for effective processing of digital video signals.
