A human object recognition unit recognizes a human object included in a captured image data. A degree-of-interest estimation unit estimates a degree of interest of the human object in acquiring information, based on a recognition result obtained by the human object recognition unit. An information acquisition unit acquires information as a target to be presented to the human object. An information editing unit generates information to be presented to the human object from the information acquired by the information acquisition unit, based on the degree of interest estimated by the degree-of-interest estimation unit. An information display unit outputs the information generated by the information editing unit.
