An information processing apparatus, comprises a first acquiring unit that acquires a photoacoustic image generated base d on an acoustic wave which is generated by light irradiation; a second acquiring unit that acquires an ultrasonic image generated based on a reflected wave of an ultrasonic wave transmitted to the object; a determining unit that determines a high accuracy region that is a region in which information is acquired with at least a predetermined accuracy in the photoacoustic image; an input unit that accepts a specification of a region of interest (ROI) on the ultrasonic image; and a displaying unit that displays the ultrasonic image and the photoacoustic image corresponding to the ROI, wherein when the inputting unit accepts the specification of the ROI, the displaying unit displays the position of the high accuracy region on the ultrasonic image in a superimposed state.
