Title: The Innovations of Masaru Shimada
Introduction
Masaru Shimada is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of technology, particularly in the realm of color television and camera systems. With a total of two patents to his name, Shimada's work has had a lasting impact on the industry.
Latest Patents
Shimada's latest patents include a white balance control circuit and a color camera system. The white balance control circuit is designed for an encoded composite color television signal. It utilizes three primary color signals—green (G), blue (B), and red (R)—which are matrixed to create mixed color signal components. The circuit provides color difference signals of R-G and B-G, and it features gain control circuits that adjust the gains of the R and B signals to achieve zero color difference during white balance adjustments.
The color camera system addresses a common issue in television displays, specifically the dot-like signals caused by processing errors. This system employs a pick-up device with a color coding filter to derive composite signals containing color components modulated at a specific frequency. An adder circuit mixes the composite signals from adjacent lines, while a detector identifies the 2nd harmonic of the modulation frequency. A dual gate MOSFET is then used to suppress high-frequency regions of the luminance signal derived from the composite signals.
