ABSTRACT:
An array of light control units has an area large enough to present images for direct viewing. The array also has light control units sufficiently dense that ordinary acuity artifacts are not noticeable in presented images when the array is directly viewed at usual viewing distances by a human with normal vision. Signal circuitry can provide signals to the light control units. The array can present an image that includes M colors, where M is more than three, even though each light control unit can only cause presentation of one of a segment with one of a set of N colors, where N is less than M. Data defining an input image with M colors are used to obtain data defining an output image that is a version of the input image but includes, for each light control unit, a color data item indicating one of its set of N colors. The signal circuitry provides signals to the light control units so that each light control unit presents a segment with the color indicated by its color data item. As a result, the array presents the output image so that its appearance to a human with normal vision viewing the array at usual viewing distances is substantially identical to the appearance the input image would have if presented.
