    摘要: A display or projection of an image as an array of pixels is, effectively, a sampling process, and pre- and post-filtering must be applied to avoid aliasing and to properly reconstruct the image. Because the sampling is performed by the display/projection of the pixels forming the image, the pre-filtering must be applied to the video signal before it is formed into pixels, and the post-filtering must be applied, optically, after the pixels are formed. The pre-filtering process can also compensate for the non-uniform characteristics of the display or the post-filtering process. As such, the occurrence and severity of visual artifacts introduced into the display or projection of an image are reduced.

    摘要: A pixelated image display system comprising: a first panel including an array of pixel elements, each pixel element partially masked by an opaque region; one or more additional panels, each additional panel including an array of pixel elements, each pixel element partially masked by an opaque region; means for directing a different subset of pixel data from an image dataset to each the panel to control the pixel elements of each panel; and means for aligning and projecting interleaved pixel elements, in at least one of the horizontal and vertical directions, from each panel onto a screen to form a pixelated image.
