Title:
METHOD OF MEASURING FLICKER SENSITIVITY DISTRIBUTION, APPARATUS FOR THE METHOD, AND COMPUTER-READABLE RECORDING MEDIUM RECORDING FLICKER SENSITIVITY DISTRIBUTION MEASUREMENT PROGRAM
Document Type and Number:
WIPO Patent Application WO/1999/020180
Kind Code:
A1
Abstract:
A method of measuring a flicker sensitivity distribution with high accuracy capable of keeping easily and reliably a fixation state of a subject without fatiguing the subject, comprising the step of flickering step-wise a target on a display screen (3) of a display (1) while changing luminance so that mean luminance of luminance when the target constituting one flickering of the target is bright and luminance when the target is dark is equal to luminance of the display screen (3) as the background of the target, and the step of determining a flicker sensitivity from luminance when the target constituting one flickering of the target is bright when flickering of the target is sensed and from luminance when the target is dark.
