Additional information, which is composed of the camera position, camera azimuth and focal distance of the taking lens, is added to image data of the captured image as tag and recorded in an image file. When the captured image is reproduced, the map image generated according to the additional information is displayed below the captured image, covering an area from the image capture point toward the subject in the captured image. Field view lines and map symbols indicating the subjects are displayed in the map image. Further, the map image includes the extension line which passes the map symbol and is extended to the subject in the captured image for showing the correspondence between the map symbol and the subject. ## Claims ### Claim 1 A map display system comprising: A. an image capture device including: an image sensor for capturing a subject;
