Abstract: A digital photo frame includes a display section, a display control section, a detection information acquisition section that acquires detection information detected by a user detection sensor, and a user state determination section that determines at least one of a positional relationship between a user and the display section, an observation state of the user with respect to the display section, and whether or not the user is positioned within a detection range. The display control section changes a display state of an image displayed on the display section corresponding to at least one of the positional relationship between the user and the display section, the observation state of the user with respect to the display section, and whether or not the user is positioned within the detection range.
