Classification: CPC A  G | IPC A  G

Claim 2:
3. A method of detecting a vision function, the method comprising:
performing display control to cause an image for determination to be displayed in a display region on a display screen of a display unit and moving the image for determination within the display region;
performing gazing point detection to detect a position of a gazing point of a test subject observing the display screen;
performing relation information detection to detect relation information between movement of the gazing point in a first direction along a moving direction of the image for determination and movement of the gazing point in a second direction orthogonal to the first direction; and
performing visual function detection to detect a visual function of the test subject based on the relation information, wherein
the performing of the visual function detection detects the visual function of the test subject based on:
a first difference between a first total moved distance of the gazing point in the first direction along the moving direction of the image for determination and a second total moved distance of the gazing point in the second direction orthogonal to the first direction; or
a second difference between a first number of times a moving direction of the gazing point is reversed with respect to the first direction along the moving direction of the image for determination and a second number of times the moving direction of the gazing point is reversed with respect to the second direction orthogonal to the first direction.
