Abstract
An analysis unit determines at least two boundaries by determining; in a coordinate system indicating a correlation between a luminance contrast value between a luminance of an attention portion and a luminance of a background portion, and a luminance average value of a visual target including the attention portion and the background portion; the boundary between a region where a subject has a visibility and a region where the subject does not have the visibility for each combination of stimulus values of a color stimulus of a visual target.
Claims27
A visual function examination system, comprising
- an analysis unit determining at least two boundaries by determining, in a coordinate system indicating a correlation between a luminance contrast value and luminance average value of a visual target, the boundary between a region where a subject has a visibility and a region where the subject does not have the visibility for each combination of stimulus values of a color stimulus of a visual target, the luminance contrast value is the contrast value between a luminance of an attention portion and a luminance of a background portion, and the luminance average value of the visual target includes the attention portion and the background portion.
A visual function examination system, comprising:
- an accepting unit accepting a result of a visual function examination obtained by sequentially presenting to a subject a visual target having at least one which is different in a combination of a luminance contrast value between a luminance of an attention portion and a luminance of a background portion, a luminance average value of a visual target including the attention portion and the background portion, and stimulus values of a color stimulus of a visual target;
- and
- based on the result of the visual function examination, an analysis unit determining at least two boundaries by determining, in a coordinate system indicating a correlation between the luminance contrast value and the luminance average value, the boundary between a region where the subject has a visibility and a region where the subject does not have the visibility for each combination of the stimulus values of the color stimulus.
A visual function examination device, comprising
- an analysis part determining at least two boundaries by determining, in a coordinate system indicating a correlation between a luminance contrast value and luminance average value of a visual target, the boundary between a region where a subject has a visibility and a region where the subject does not have the visibility for each combination of stimulus values of a color stimulus of a visual target, the luminance contrast value is the contrast value between a luminance of an attention portion and a luminance of a background portion, and the luminance average value of the visual target includes the attention portion and the background portion.
A visual function examination method, comprising
- determining at least two boundaries by determining, in a coordinate system indicating a correlation between a luminance contrast value and luminance average value of a visual target, the boundary between a region where a subject has a visibility and a region where the subject does not have the visibility for each combination of stimulus values of a color stimulus of a visual target, the luminance contrast value is the contrast value between a luminance of an attention portion and a luminance of a background portion, and the luminance average value of the visual target includes the attention portion and the background portion.
A non-transitory computer-readable storage medium storing a program causing a computer to execute processing
- determining at least two boundaries by determining, in a coordinate system indicating a correlation between a luminance contrast value and luminance average value of a visual target, the boundary between a region where a subject has a visibility and a region where the subject does not have the visibility for each combination of stimulus values of a color stimulus of a visual target, the luminance contrast value is the contrast value between a luminance of an attention portion and a luminance of a background portion, and the luminance average value of the visual target includes the attention portion and the background portion.
