Abstract
An information processing apparatus uses signals obtained by a plurality of reception units that receive an acoustic wave propagating from a point of interest to acquire object information at the point of interest. The apparatus includes a speed-of-sound acquisition unit that acquires information representing speed of sound on a propagation path of the acoustic wave, a correction unit that acquires a correction amount for the information representing speed of sound and corrects the information representing speed of sound using the correction amount, and an information acquisition unit that determines a propagation time of the acoustic wave by linearly approximating propagation paths from the point of interest to the reception units based on the corrected information and acquires the object information at the point of interest based on the signals and the propagation time.
