Title: Kazuya Uyeda: Innovator in Contour Restoration Technology
Introduction
Kazuya Uyeda is a notable inventor based in Suita, Japan. He has made significant contributions to the field of video signal processing, particularly in contour restoration technology. With a total of 3 patents to his name, Uyeda's work has had a considerable impact on the industry.
Latest Patents
One of Uyeda's latest inventions is a contour restoration apparatus. This apparatus features a series of delay circuits that are connected in sequence. It includes maximum and minimum value detection circuits that identify the highest and lowest values from an input video signal and the output signals of the delay circuits. A mean value circuit calculates the average of these maximum and minimum values. The mean value is then subtracted from a delayed signal, which has a delay time that is half of the total delay time from all the delay circuits. An adder combines the result of this subtraction with the delayed signal. The output is processed through a non-linear processing circuit, which outputs the adder's signal if it falls between the maximum and minimum values. Additionally, a contour extraction circuit multiplies a centrally located signal among the input video signal and its surrounding signals with a predetermined coefficient. The results are then combined through a series of adders, and a contour amplitude circuit detects the difference between the maximum and minimum values to determine a coefficient based on this difference. Finally, a mixer combines the outputs of the non-linear processing circuit and the additional adder.
