An information-processing apparatus captures either or both of an ultrasonic image and a photoacoustic image that are imaged by an imaging device, obtains operation information about manipulation of the imaging device for instructing an imaging method and time of the manipulation regarding either or both of the ultrasonic image and the photoacoustic image, obtains time information about either or both of time at which the ultrasonic image is captured and time at which the photoacoustic image is captured, and outputs, to an external device, the operation information, the time information, and either or both of the ultrasonic image and the photoacoustic image that are associated with each other.
