An electronic camera which photographs images of an object, outputs image signals corresponding to the images, and stores the image signals with an assigned file name. A display on the electronic camera displays images corresponding to the stored image signals. Along with each displayed image signal, the electronic camera's display also displays the assigned file name and a frame number. If a user chooses to delete a particular image, the frame numbers for stored image signals following the deleted image are advanced by one, in order to maintain an unbroken numerical sequence. The file names assigned to each stored image signal will remain unchanged.
