The present invention is directed to a physiological recording device, or other types of sensors to detect a biopotential, and more particularly, a physiological recording electrode that can be used without skin preparation or the use of electrolytic gels. According to the method and system, reports are obtained that relate to data contained in a geographic database. In the controller 2, a receiving unit 21 receives the identification result transmitted from the renderer 4, and the display 27 performs a process of allowing a user to recognize a command to provide instructions about handling executable to the content to be played back among commands to provide instructions about handling of content in the renderer 4 based on the identification result. In the printer, processing which is the inverse of processing carried out in processing means of the digital camera and inverse AWB processing which is the inverse of the first AWB processing is carried out on the output image data, and inverse AWB image data which can be regarded as the original image data are obtained.
