Latest Patents

Nagashima's latest patents include a "Method and apparatus for coding and decoding image data using critical points." This invention presents an image data coding and decoding technique that achieves optimal compression of image data. The process involves inputting image data and separating it into key frames and intermediate frames. Per-pixel matching is computed between the key frames, allowing for the generation of a virtual intermediate frame through interpolation. The difference between the virtual frames and actual intermediate frames is encoded with minimal codes, enhancing efficiency.

Another notable patent is the "Image-effect method and image interpolation method." In this invention, an image input unit acquires a first and a second image. A matching processor computes pixel matching between the images to identify corresponding points on the second image based on a mesh defined on the first image. The results are recorded as a corresponding point file, which allows for the generation of an intermediate image. This method reduces data size by focusing on corresponding lattice points rather than individual pixels, facilitating efficient implementation in various applications, including image effects and motion picture compression.
