Patent Images

1. A method of de-blurring images by estimating point spread functions (PSFs), the method comprising the acts of:

  • receiving image data corresponding to a captured image;

    identifying a plurality of shapes within the captured image;

    estimating a plurality of shape spread functions corresponding to each of the plurality of shapes;

    determining the best matching angular velocity parameters to said plurality of shape spread functions;

    calculating the PSF from the determined angular velocity parameters; and

    de-blurring said image data using the calculated PSF.
