An information processing apparatus includes a motion information receiving portion that receives multiple pieces of motion information, which is time-series information, a motion information alteration portion that alters a positional relationship in a time axis direction between the multiple pieces of the motion information, a correlation information acquisition portion that acquires, for multiple pieces of the motion information, correlation information, which is information relating to a correlation between pieces of the motion information, and a motion information acquisition portion that acquires, based on the correlation information acquired by the correlation information acquisition portion, multiple pieces of the motion information having a positional relationship in the time axis direction at which the correlation between the pieces of the motion information is optimal. This configuration makes it possible to align multiple pieces of information relating to motion in a good balance as a whole, without disturbing their original waveforms.
