Abstract: Provided is a cognitive experiment method for change in periphery region image quality for parameter determination of a foveated hologram. According to an embodiment, a cognitive experiment method for determining foveated image parameters includes: generating a foveated image which includes a foveal region and a periphery region while reducing image quality regarding the periphery region; displaying the generated foveated image; receiving an input of a response to image quality of the periphery region from a subject; and collecting information regarding appropriate image quality of the periphery region, based on the response inputted by the subject. Accordingly, in applying a foveated hologram generation algorithm for real-time reproduction, various parameters such as a boundary between a foveal region image and a periphery region image in a foveated hologram, and a degree of quality degradation of the periphery region image may be appropriately determined through a cognitive experiment.
