A photoacoustic apparatus disclosed in this specification includes a light source； a probe including a plurality of transducers each configured to receive a photoacoustic wave generated from a subject irradiated with light emitted from the light source and output a reception signal, and a support member configured to support the plurality of transducers so that directivity axes of the plurality of transducers are collected； a moving unit configured to move the probe； a region setting unit configured to set an imaging region； and a processing unit configured to acquire subject information in the imaging region based on the reception signals output from the plurality of transducers. The light source is configured to emit the light if a position at which the directivity axes are collected is farther from the probe than a center of the imaging region.
