Abstract: A contrast sensitivity measurement apparatus (1) generates a stimulating image to be output to an external display device (20) for measuring contrast sensitivity of a user. An image scale setting unit (12) determines the spatial frequency in units of pixels on the basis of an observation distance, physical characteristics of the external display device (20), and visual characteristics of a human. A carrier waveform generation unit (13) generates a luminance map in which a change of luminance along a first axis follows the spatial frequency. A contrast map generation unit (14) generates a contrast map in which contrast gradually decreases from one end to another end along a second axis, and an equal contrast line forms a given waveform. A stimulating image synthesis unit (15) generates the stimulating image by synthesizing the luminance map and the contrast map.

Abstract: A display unit (16) outputs a stimulating image to an external display device (20). The stimulating image is obtained by synthesizing a luminance map in which luminance of each pixel is set in such a manner that a change in the luminance along a first axis follows a given spatial frequency, and a contrast map in which contrast of each pixel is set in such a manner that the contrast gradually decreases from one end to another end along a second axis and that an equal contrast line forms a given waveform. A response data generation unit (22) acquires a contrast value corresponding to each of the coordinates acquired by a user input receiving unit (21). A sensitivity calculation unit (23) calculates contrast sensitivity. A result output unit (25) outputs contrast sensitivity while adding reliability of the contrast sensitivity calculated by a reliability calculation unit (24) thereto.

Abstract: A video is superimposed on an object in order that the object will be perceived as if the object were given a motion. This video is a video including a luminance motion component corresponding to a motion given to the object.
