Abstract: A visual perception function evaluation system 10 includes: a display device 12 configured to three-dimensionally display a three-dimensional test image 20 including an object 22 to a subject; a processing device 13 connected to the display device 12; and an input device 11 through which a reply related to whether the object 22 can be perceived is input from the subject to the processing device 13. The processing device 13 includes a display control means 15 for controlling the state of display of the test image 20 on the display device 12, and a neglect region specifying means 16 for specifying a neglect region in a three-dimensional space based on the reply. The display control means 15 controls display so that the three-dimensional position of a display point P varies over time. The neglect region specifying means 16 determines three-dimensional position information on a boundary part between a perception region and the neglect region based on a position of the display point P where it is replied that the object 22 cannot be perceived and an adjacent position of the display point P where it is replied that the object 22 can be perceived.
