1. An information processing apparatus, comprising: an irradiation means for irradiating the user with light having a first wavelength and light having a second wavelength that is different from the first wavelength; an acquisition means for acquiring a first image and a second image, the first image being obtained by receiving reflected light of the light having the first wavelength with which the user is irradiated, the second image being obtained by receiving reflected light of the light having the second wavelength with which the user is irradiated; an object area extraction means for extracting an object area in which an object representing a predetermined skin portion of a body of the user is displayed, from a skin display area in a display image including the skin display area in which a skin of the user is displayed, based on the first and second images; and a distance change detection means for detecting a change in relative distance from the irradiation means to the object in accordance with a change of luminance values of pixels constituting the object area in the display image or a value calculated based on the luminance values.
