Title: Hiroya Ito: Innovator in PLL Circuits and Image Data Processing

Introduction

Hiroya Ito is a notable inventor based in Hashima, Japan. He has made significant contributions to the fields of electronics and image processing, holding a total of 5 patents. His work primarily focuses on phase-locked loop (PLL) circuits and image data processing apparatuses.

Latest Patents

Hiroya Ito's latest patents include a PLL circuit and a phase lock detector. The PLL circuit outputs an oscillation clock signal that is synchronous with a reference clock. It features a phase lock detector that identifies any phase differences between the oscillation clock signal and the reference clock. When a phase difference is detected, a charge pump circuit adjusts the oscillation clock signal to restore synchronization. The charge pump selects between ground potential and power supply potential based on the comparison results, producing an output that alternates between these potentials.

Another significant patent is an image data processing apparatus designed to prevent shifts in the period of a horizontal timing signal. This apparatus includes a separator, a phase-locked loop, a detector, a compensator, and a timing signal generator. The detector generates multiple delayed timing signals to measure phase differences and the period of the horizontal sync signal. The compensator adjusts the ratio for combining luminance data based on these measurements, ultimately generating compensated luminance data.
