Title: The Innovations of Toshio Idei
Introduction
Toshio Idei is a notable inventor based in Nagaokakyo, Japan. He has made significant contributions to the field of video signal processing, holding a total of 3 patents. His work has had a lasting impact on the technology used in display devices.
Latest Patents
One of Idei's latest patents is a color video signal synthesizer. This innovative device is designed to provide a multiplex video signal that creates a picture-in-picture effect on display screens, such as those found in cathode ray tubes. The synthesizer employs a phase-locked loop (PLL) circuit to generate a carrier signal that is synchronized with the color burst signal in the composite video signal. This allows for the reproduction of the main picture while simultaneously displaying a sub-picture. The carrier signal is delayed and used to remodulate the sub-picture signal, which has been time-compressed. The result is a seamless time-division multiplexing of both signals without altering the characteristics of the color composite video signal.
Another of his patents focuses on a video signal synthesizer specifically for producing a picture-in-picture effect. This device also utilizes a phase-locked loop circuit to generate a carrier wave that is synchronized with the color burst signal of the main picture. The carrier wave modulates a time-compressed second composite signal representing the sub-picture. A time-division multiplexer is then employed to combine the two video signals, resulting in a picture-within-a-picture video signal suitable for display devices.
