ABSTRACT:
A method and apparatus for providing an improved area of interest display system by providing a transition zone between a high resolution image being reflected onto and a low resolution image being projected onto a display screen. A combiner surface is provided in the form of a mirror having an all-reflective surface which transitions to an all-transmissive surface. The transition occurs in the form of pixels of highly reflective material which are disposed on the combiner surface using a dithering pattern generated from a modified error diffusion algorithm which minimizes undesired grouping of pixels.
