An object information acquiring apparatus of the present invention includes a receiver that receives an ultrasound echo and a photoacoustic wave, a scanner of the receiver, a processor that generates structural distribution information and functional distribution information, and a controller that causes a display to display each of the distribution information items. The controller causes, during the period in which the receiver receives the photoacoustic wave from a partial region formed of at least a part of the object and in which the processor generates the functional distribution information on the partial region, the display to sequentially display the structural distribution information generated by the processor on the basis of the ultrasound wave reflected from the partial region as the scanner moves the receiver to implement scanning.
