In one embodiment, upon performing continuous shooting of a print product plural times, shooting is performed while changing the image capturing condition of the device, and information of the watermark is obtained based on plural captured images. Even if the device is moved to perform shooting separately plural times, it can be prevented that the distance to the print product cannot be adjusted owing to occurrence of a camera shake, and a captured image becomes out of focus. A user holds the device by the hand and can accurately perform shooting.
