Latest Patents

One of his latest patents is the "Contour Correction Signal Generating Circuit." This vertical contour correcting circuit provides contour correction of a luminance signal at horizontal color transition areas of an image. It minimizes dot interference in reproduced images by utilizing a vertical band-pass filter to output a level difference signal. The circuit processes this signal through multiple delays to produce an intermediate value signal, which is then combined to cancel out carrier color signal band components.

Another significant patent is the "Advanced Comb Filter." This method determines a chrominance element for pixel signals of an optical image using a 1H delay circuit. The pixel signals are filtered through a band-pass filter to eliminate low-frequency luminance components. The resulting signals are compared to generate a combed chrominance component, ensuring optimal output based on the greater value.
