1. A cognitive experiment method for determining foveated image parameters, the method comprising:
generating, by a foveated image generation system, a foveated image which comprises a foveal region and a periphery region while reducing image quality regarding the periphery region;
displaying, by a display system, the generated foveated image;
receiving, by an input device, an input of a response to image quality of the periphery region from a subject;
collecting, by the foveated image generation system, information regarding appropriate image quality of the periphery region, based on the response inputted by the subject through the input device,
wherein the displaying comprises displaying a mark for checking whether a gaze of the subject remains in the foveal region,
wherein the mark has a shape randomly changed at a certain time; and
receiving an input of a response as to a change state of the mark from the subject,
wherein the collecting comprises, only when the response as to the change state is correct, collecting the information regarding the appropriate image quality of the periphery region based on the response inputted by the subject.
