ABSTRACT:
A method and apparatus for eliminating aliasing in an electronic still camera without the use of a birefringent filter is disclosed. Instead of a birefringent filter, mechanical dithering is utilized to move the pixel elements of a solid-state imager in a controlled manner with respect to an incident image. The movement of the pixel elements by mechanical dithering spreads light from the incident image among neighboring pixels of the image sensor and therefore performs the same function as a birefringent filter to prevent aliasing in an electronic camera.
