Title: Manabu Yumine: Innovator in Video Signal Processing
Introduction
Manabu Yumine is a notable inventor based in Kadoma, Japan. He has made significant contributions to the field of video signal processing, holding a total of 3 patents. His work focuses on enhancing the efficiency and quality of video signal transmission and processing.
Latest Patents
Yumine's latest patents include a vertical synchronizing signal generation apparatus and a video signal processing apparatus. The vertical sync signal generator features a vertical sync signal separation circuit that separates a vertical sync signal from an input luminance signal. It outputs the separated signal as a first vertical sync signal. Additionally, it includes an automatic frequency control circuit that generates a second vertical sync signal with a repeat frequency corresponding to the average repeat frequency of the first vertical sync signal. A vertical sync signal phase detection circuit detects whether the first vertical sync signal has two different periods repeated alternately, outputting the result as a decision signal. A selector then chooses between the first and second vertical sync signals based on the decision signal.
His video signal processing apparatus includes a DD converter circuit that interpolates a digital video signal locked to a 14.3-MHz burst clock. This circuit converts the sampling data to be locked to a 13.5-MHz free-run clock. It also features a frame memory circuit that writes the digital video signal output by the DD converter on the 14.3-MHz burst clock and reads it on the 13.5-MHz clock. This innovation allows for the rate conversion of digital video signals without the need for an analog PLL circuit.
