Abstract
An image processing apparatus includes a spectral image acquisition unit configured to acquire a spectral image that is an image generated using photoacoustic signals corresponding to a plurality of different wavelengths, based on photoacoustic waves generated by radiating lights with the plurality of different wavelengths to an object into which a contrast agent has been injected, a contrast agent information acquisition unit configured to acquire information about the contrast agent, a region determination unit configured to determine a region corresponding to the contrast agent in the spectral image on the basis of the information about the contrast agent, and a display control unit configured to display the spectral image such that the region corresponding to the contrast agent is distinguishable from a region other than the region corresponding to the contrast agent.
