His work has had a lasting impact on how video signals are processed and enhanced.

Latest Patents

Miyahara's latest patents include groundbreaking technologies in digital video effects and phase locking systems. The first patent, titled "Digital Video Effect Equipment," focuses on providing special effects by controlling the number of quantization levels for each sample of an incoming television video signal. This technology converts each video signal sample into a digital signal comprising a predetermined number of binary digits. A gradation modification circuit decreases the gradation represented by the digitized video signal, which is then reconverted to an analog signal. The resultant special effects give the video picture an oil-painting-like impression, enhancing the visual experience for viewers.

The second patent, "Phase Locking System for Television Signals Using a Digital Memory," addresses the synchronization of incoming composite video signals with reference wave synchronizing signals. This system locks the incoming signal at a rate dependent on the incoming color subcarrier, utilizing a memory to strobe the signal on a field-by-field basis. The circuitry groups the fields on a repeating field-tagged basis, maintaining signal integrity, particularly for the NTSC signal format.
