Latest Patents

Isobe's latest patents include a video signal processing device and a display apparatus. In the video signal processing device, the first color space converting section performs color space conversion on an input video signal, generating a converted video signal configured of H, S, and V signals. The first high-frequency separating section separates a high-frequency component from the luminance signal in the input video signal, producing high-frequency luminance signals. The combining section then performs a combining process based on the V signal or the S signal or both, along with the high-frequency luminance signal, to generate a combined V signal or a combined S signal or both. The second color space converting section further processes the video signal, configured of the H signal, the S signal or the combined S signal, and the V signal or the combined V signal, to produce an output video signal defined in RGB color space.

Another notable patent is the three-dimensional video signal generator and three-dimensional video. This generator features a high-definition video signal source that produces left and right high-definition video signals. These signals serve as left and right video signals during the effective scanning periods of odd-numbered and even-numbered field signals of an interlaced-scanning high-definition video signal composed of 1125 scanning lines, with an interlace factor of 2:1. The left and right video signals are vertically compressed in time with a compression ratio of 11:5. The compressed signals are then combined into a three-dimensional video signal, with a pseudo vertical blanking period inserted between them.
