A subject information obtaining apparatus includes a probe including a receiver that receives an acoustic wave to be converted to an electric signal and first and second irradiation units that irradiate mutually different areas on a subject surface with pulsed light, a control unit that controls illumination positions of the pulsed light to avoid continuous irradiation of the subject with the pulsed light from the first and second irradiation units, and a signal processing unit that performs averaging or integrating of electric signals derived from the pulsed light illuminated from the first and second irradiation units and obtains a characteristic distribution in the subject by using the averaged or integrated signal or performs combining of distributions obtained by using electric signals derived from the pulsed light illuminated from the first and second irradiation units and obtains a combined distribution as the characteristic distribution in the subject.
A subject information obtaining apparatus that obtains a characteristic distribution in a subject, the apparatus comprising:
A subject information obtaining method of irradiating a subject with pulsed light generated by a light source from a first irradiation unit and a second irradiation unit and obtaining a characteristic distribution in the subject by using an electric signal output from a receiver that receives an acoustic wave generated in the subject through irradiation with the pulsed light, the method comprising:
