Abstract: A main electronic imaging device takes in as a taken-image an image of a subject obtained through an imaging lens. An electronic finder device photoelectrically first generates the image of the subject and generates an image signal. Based on the generated image signal, the electronic finder device places the imaging range PA substantially at the center, generates an image of finder range FA that is one size larger than the imaging range PA, and provides the image of finder range FA that is generated with an imaging frame 47a that expresses the outer border of the imaging range so as to obtain the image as a finder image, and controls so that the finder image is displayed on a display 47. As a result, the imaging range PA is smaller than the finder range FA but is smaller by only one size. The ratio occupied by the imaging range PA within the finder range FA is accordingly sufficiently large, and the imaging range PA can be recognized easily and without fail.
