Shawn M. Swilley 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).

  • Image generation with interpolation of pixels on a grid to pixels on a scan trajectory
    Patent number: 8274522
    Abstract: An image generation apparatus provides interpolation and distortion correction. The interpolation and distortion correction may be provided in one or two dimensions. Nonlinear image scan trajectories, such as sinusoidal and bi-sinusoidal trajectories are accommodated. Horizontal and vertical scan positions are determined using a linear pixel clock, and displayed pixel intensities are determined using interpolation techniques.
    Type: Grant

  • Electronic alignment of primary color pixels in a scanned display
    Patent number: 8223161
    Abstract: An image generation apparatus provides correction for color offsets. Color offsets may be caused by misalignments in laser diodes or optics assemblies in a laser projector. The offsets may be measured during or after manufacture of the laser projector. An image buffer is responsive to the offset data to translate each color plane separately. The image buffer may include separately addressable portions for each color. Further, variable delay elements on the output of the image buffer may provide color offset correction. Interpolation provides further offset correction.
