Document Type and Number:

WIPO Patent Application WO/2018/012334

Kind Code:

A1

Abstract:

This visual function test system includes an analyzing means which obtains at least two boundaries by obtaining a boundary between a region in which a subject has visibility and a region in which the subject does not have visibility, for each combination of stimulus values of color stimuli of a visual target, in a coordinate system representing a correlation between a luminance contrast value of the luminance of a part of interest and the luminance of a background part, and an average value of the luminance of an index including the part of interest and the background part.
