Provided is a display data obtaining apparatus capable of, in photoacoustic tomography, reducing a fluctuation in sensitivity which depends on location for image reconstruction even in a limited measurement condition in which a photoacoustic wave generated in the entire subject cannot be obtained in a sufficient range. The display data obtaining apparatus includes: an acoustic wave detecting unit for detecting an acoustic wave generated from a subject irradiated with pulsed light to obtain a signal; a first data deriving unit for deriving first data exhibiting an optical characteristic distribution of the subject based on the obtained signal obtained by the acoustic wave detecting unit; a memory for storing spatial sensitivity distribution data specific to the display data obtaining apparatus; and a second data deriving unit for deriving second data exhibiting the optical characteristic distribution of the subject using the first data and the spatial sensitivity distribution data.
