    Abstract: The present invention provides a camera-equipped cellular terminal capable of receiving visible light communication. In order to receive information from visible light, a light receiving unit (24) for visible light pointing to the same direction as a light receiving lens of the camera (21) is provided other than a camera (21) of a conventional camera-equipped cellular terminal (20). This light receiving unit (24) receives information from the visible light. This light receiving unit (24) may be configured by a photodiode or the like. When the camera (21) is used as a finder to display an illuminating device conducting visible light communication in a display of the camera, whether the light receiving unit 24 can receive information through visible light communication is determined.
