Paper Abstract

A methodology for measuring observer internal noise has been extended to measure display perceptual noise. Observer performance experiments were performed in which the observer's task was to detect and locate several test objects (dots) at random locations in a noise field. From this Free-Response Receiver Operating Characteristic (FROC) experiment the ROC detectability parameter d' was extracted. By performing this experiment at two levels of the externally added noise, one can determine the noise added by the display and the observer. The method takes into account the contrast of the display, the pixel size and the viewing distance.
