Abstract
In a camera capable of zooming, a range narrower than an ordinary photographing imaging field range can be specified as a printing range by a pseudo telephoto mode. A horizontally long area can be specified as a printing range by blocking photographing light beams at upper and lower portions of the ordinary imaging field range in a panorama mode. This mode state is discriminated by a mode state discriminating mechanism. When a latest mode discriminated by the mode state discriminating mechanism is the pseudo telephoto mode, a canceling mechanism cancels the panorama mode even if a mode preceding to the latest mode is the panorama mode.
