A camera device includes an image data generation unit which generates image data corresponding to a captured image; a specific information generation unit which generates specific information relating to the image data; a recording unit which records the image data and the specific information on a removable recording medium which is removably attachable to the camera device; a reproducing unit which reproduces the image data and the specific information from the removable recording medium; an embedding unit which controllably embeds the reproduced specific information into the reproduced image data using a digital watermarking technique; and a control unit which controls the embedding unit to embed the reproduced specific information into the reproduced image data if a first process is selected by a user, and controls the embedding unit not to embed the reproduced specific information into the reproduced image data if a second process is selected by the user.
