A dual-panel display system is provided that comprises control modules and algorithms to select codeword pairs (CWs) to drive a first image-generating panel and a second contrast-improving panel. The first codewords is selected by considering some characteristics of the input image data (e.g., peak luminance) and to improve some image rendering metric (e.g., reduced parallax, reduced contouring, improved level precision). The first codeword may be selected to be the minimum first codeword within a set of codeword pairs that preserves the peak luminance required by the input image data. Also, the first codeword may be selected to minimize the number of Just Noticeable Difference (JND) steps in the final image to be rendered. The second codeword may be selected to similarly improve image quality according to a given quality metric.

A stereoscopic imaging assembly for converting true visual images of a real-life subject to a stereoscopic image includes a display and an analyzer. The display is preferably a liquid crystal display, which includes first image pixels, second image pixels, and a polarizer. The first image pixels are responsive to a first electronic image of a first true visual image and the second image pixels are responsive to a second electronic image of a second true visual image. The polarizer has a first polarization material, which enables transmission of light of a first polarity, while blocking light of a second polarity, thereby transmitting a first polarized image having a first polarity. A second polarization material enables transmission of light of the second polarity, while blocking light of the first polarity, thereby transmitting a second polarized image having a second polarity. The analyzer delivers the first polarized image to the first eye of an observer while excluding the second and delivers the second polarized image to the second eye while excluding the first, which enables the observer to synthesize the first and second polarized images into a stereoscopic visual image.
