Summary:An image generation method for generating a sound image on the basis of signal data of sound waves obtained by measuring a predetermined test site, said image generation method comprising: a step for reconstructing a temporary measurement image comprising the sound image on the basis of the signal data; accepting designation of a local region of interest in the temporary measurement image; a region-of-interest image reconstruction step for sequentially reconstructing region-of-interest images comprising the sound image on the basis of the changed sound velocity parameter while changing the sound velocity parameter for the region of interest; determining an appropriate value of the sound velocity parameter on the basis of the region-of-interest image; and reconstructing a sound image of a region wider than the region of interest on the basis of the appropriate value of the sound velocity parameter, in which, in the step of reconstructing the temporary measurement image, the amount of calculation per unit area
