ABSTRACT:
A lens includes mechanical dithering that displaces pixels adjacent to undithered pixels. The dithering, for example, precisely places pixels above, below, and on both sides of the undithered pixel. Image data is supplemented with interpolation and/or new data in additional pixel locations. The image data may be projected by a dithered lens.
