Latest Patents

Mari Kaneko holds a patent for a three-dimensional Y/C separating circuit. This invention provides a high level of responsiveness to motion in video signals while reducing memory capacity. The circuit features a 2-frame memory that delays a color signal by an inversion period to produce a delayed composite video signal. It includes a luminance motion detecting part that generates a first frame correlation signal through subtraction processing between the delayed composite video signal and the composite video signal. Additionally, an adding circuit produces a mixed video signal through addition processing. A frame memory delays the mixed video signal by one frame period, while a subtracting circuit creates a second frame correlation signal. A determining circuit assesses motion from the first and second frame correlation signals, producing a mixing ratio controlling signal. Finally, mixing circuits output luminance and color signals based on this controlling signal. This patent showcases her innovative approach to enhancing video technology.
