Provided are a photoacoustic image generation apparatus, a photoacoustic image generation method, and a photoacoustic image generation program that can perform a more appropriate reconstruction process regardless of the type of probe, without causing a reduction in the speed of an arithmetic process. It is identified whether a probe that detects photoacoustic waves and outputs a photoacoustic wave detection signal is a probe in which detection elements are arranged by a coordinate system using polar coordinates or a probe in which detection elements are arranged by a rectangular coordinate system. In a case in which the probe is identified as the probe in which the detection elements are arranged by the coordinate system using the polar coordinates, a time domain reconstruction process is selected to generate a photoacoustic image.
