Abstract
Abstract While a camera portion and a body portion having a display portion or a recording portion are separated from each other, a signal can be bidirectionally communicated between them by wireless communication circuits which are respectively provided in the camera portion and the body portion. A camera control circuit included in the camera portion transmits, to the body portion by wireless communication, information concerning a remaining amount of energy of a battery of the camera portion or information concerning a photographing state of the camera portion. The body portion displays, on a screen of an image display portion, a variety of information signals received by wireless communication, in such a manner as to be superimposed on an image photographed by the camera portion.
