He has made significant contributions to the field of video signal processing, holding 2 patents that showcase his innovative approach to technology. His work has had a lasting impact on the way video signals are processed and displayed.

Latest Patents

One of his latest patents is a video signal processing device for writing and reading a video signal. This invention involves writing an input video signal into alternate field memories according to a timing clock from an input video clock generator. The display video signal is then alternately read from these field memories, based on a timing clock from a display video clock generator. The circuit includes an address observation mechanism that judges whether a read/write address passes by a write/read address, ensuring efficient reading and writing operations. This arrangement provides a relatively simple structure for preventing a match of read and write addresses.

Another significant patent is a television receiver equipped with a delay circuit. This television receiver comprises a video signal processing circuit that generates three primary color signals from an input composite video signal. The delay circuit is coupled in series to the video signal demodulating circuit and works in conjunction with a parallel circuit system that has virtually no delay time. The delay circuit's performance is described by a specific relation involving the horizontal scanning period and the delay time of the signal system.
