  • 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
    Filed: December 1, 2010
    Date of Patent: September 25, 2012
    Assignee: Microvision, Inc.
