We have developed a simple model of human sensitivity to spatial contrast patterns, called the Spatial Standard Observer. This model can be applied to numerous problems in display inspection and measurement. In this paper I describe two examples: measurement of mura and measurement of motion blur. In each case the Spatial Standard Observer can provide a measure of the artifact in units of just‐noticeable differences.
