1. A photoacoustic imaging apparatus comprising:

  • a light source;

    a detector configured to convert an acoustic wave into an electric signal, the acoustic wave being generated from an optical absorber in a measurement target by irradiating the measurement target with light emitted from the light source; and

    a signal processing unit configured to obtain an image of the measurement target based on the electric signal,wherein the signal processing unit is configured to determine whether an optical absorption coefficient of the optical absorber is lower or higher than an optical absorption coefficient of a surrounding region of the optical absorber based on the electric signal and obtain the image based on a result of the determination.
