Title: Innovations of Jong-gyu Lee

Introduction

Jong-gyu Lee is a notable inventor based in Gyeonggi, South Korea. He has made significant contributions to the field of video cassette recorders (VCRs) through his innovative patents. With a total of 3 patents, Lee has demonstrated his expertise and commitment to advancing technology in this area.

Latest Patents

One of Jong-gyu Lee's latest patents is a method and apparatus for controlling the speed of the capstan motor of a video cassette recorder. This invention involves modulating a capstan frequency generating (CFG) signal into a pulse signal. The method calculates time intervals corresponding to the rising and falling edges of the pulse signal. These intervals are then compared to a target time to obtain a difference, which is used to compensate the rotation speed of the capstan motor.

Another significant patent by Lee is a method for controlling the tracking position during low-speed reproducing in a video cassette recorder. This method enhances noise suppression and improves image quality. It involves detecting the period of an envelope waveform of a video signal reproduced by the main heads and generating a pseudo head switching pulse (PHSP) signal accordingly. The tracking position is then traced at the point where the voltage level of the envelope waveform is the highest within one period of the PHSP signal.
