Masazumi Katayama has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Methods for creating an image for a three-dimensional display, for calculating depth information and for image processing using the depth information
    Patent number: 6384859
    Abstract: A method is proposed for automatically obtaining depth. information from a 2-D motion image, so as to create an image for a 3-D display. Further, methods are proposed for selecting appropriate frames for the calculation of the depth information, or discontinuing the calculation, and for conducting image., processing using the depth information. Examples of various types of image processing can be listed as including the creation of a viewfinder image seen from a different point, natural scaling operations to an image area, and separation of a desired image area. First, a motion information of an object on a screen is extracted by block matching or the like. Second, the actual movement of the object in the 3-D world is calculated.
