Abstract: A tool written in MatLab is described that can be used to simulate display devices. Images as they would appear on the simulated display can be rendered on a workstation screen for direct visualization of the simulated data. The tool also produces a two-dimensional matrix of CIE XYZ vectors that corresponds to the photometric measure of the simulated display with an image rendered on it. This tool is part of a larger effort to build a CAD tool for flat panel display design and optimization. Use of the tool is illustrated with examples of multi-level error diffusion. An empirical experiment is described comparing the predictions of the CAD tool set to actual human performance. The system is found to be consistent with human psychophysics and useful for device design and optimization. !11
