A camera includes an image sensing unit that generates unprocessed image
data, an image processing unit that processes the unprocessed image data,
an embedding unit that embeds first additional information in the
processed image data using a digital watermarking technique, an attaching
unit and a recording unit. The attaching unit attaches the first and
second additional information to the unprocessed image data. The second
additional information indicates to an external device that if the device
generates processed image data from the unprocessed image data, it is to
embed the first additional information in the processed image data using
the digital watermarking technique. The recording unit records the
processed image data, in which the first additional information is
embedded, to a removable recording medium, in a first image recording
mode, and records the unprocessed image data, to which the first and
second additional information are attached, to the removable recording
medium, in a second image recording mode.
