Latest Patents
One of Kouguchi's latest patents is a "Ghost cancelling device using variable amplifier controlled by criterion." This invention addresses the issue of ghosting in video signals by employing a filter that derives an output video signal. The device utilizes a weight setting circuit to control the filter frequency response, effectively eliminating ghosts from the input video signal. The control signal for the weight setting circuit is generated by analyzing the video signals to detect specific characteristics, allowing for precise adjustments to the filter.
Another significant patent is the "Motion-adaptive device for separating luminance signal and color signal." This invention features a motion detector that identifies motion within a composite color television signal. It generates a motion signal that aids in extracting the color signal from the composite signal. By employing a spatiotemporal filter, the device can vary the pass band of the spatial filter according to the detected motion, resulting in improved separation of luminance and color signals.
