An information processing apparatus which processes image data indicating characteristic information at a plurality of positions inside an object based on an acoustic wave generated when the object is irradiated with light via a light irradiating unit, the positional relationship of which with an acoustic probe is defined. The information processing apparatus includes an image data acquiring unit configured to acquire the image data an information acquiring unit configured to acquire identification information which identifies a type of the acoustic probe and a correcting unit configured to correct, based on the identification information, an effect on an image value of the image data attributable to a variation in light intensities, at the plurality of positions inside the object, of light irradiated via the light irradiating unit.
