When the mode of an electronic camera is set at folder creation mode and a release button is pressed, a new folder is created in a recording area of a recording medium and an icon image of the newly created folder is created. The icon image is created based on image data photographed in response to the press of the release button. A list of folders created in the recording medium is displayed with folder icons on an image display device and an icon image is displayed on each folder icon. From the displayed list of folders, the user selects a folder for recording the image data.
