<p>The measurement method involves a step for displaying on a display screen an image in which one corresponding region exclusively that has been selected from a plurality of regions provided has a contrast difference when on and when off; a step for enlarging the contrast difference in the image display in cases which an operation for an operation unit accompanying the flickering perception of a subject is assessed to not be correctly specifying the one aforementioned selected region, and, in cases which a correct specification has been assessed, recording the contrast difference at that point in a recording unit as the measurement contrast difference; and a step for assessing whether or not the aforementioned recorded measurement contrast difference has converged, reducing the contrast difference when a lack of convergence has been assessed, and determining the convergence value of the aforementioned measurement contrast difference as information corresponding to the flickering perception threshold when convergence has been assessed. The measurement method is capable of objectively measuring the flickering perception threshold in a short period of time, and is capable of objectively measuring the mental fatigue of an individual.</p> |
