1. A method for use in a scanning beam display of producing an image in response to image data that represent desired pixels, each desired pixel having a respective desired pixel location, comprising the steps of:

  • emitting a beam of light;

    resonantly scanning the light along a first axis at a first frequency through a series of actual pixel locations;

    for each actual pixel location identifying a plurality of desired pixel locations corresponding to the actual pixel location;

    determining for each of the identified pluralities of desired pixel locations a corresponding set of weighted data as a function of the first frequency and the image data for the respective desired pixel location; and

    modulating the beam of light according to the weighted data, when the beam of light is aligned with the corresponding actual pixel location.
