First Claim
1. An image display comprising:
- a display panel configured to substantially simultaneously display a map picture and a photo picture;
a map data storage device to store map data;
a map picture preparing device that reads the map data stored in said map data storage device, and prepares the map picture based on the read map data and a first coefficient of composition, α
;
a map picture display device that displays the map picture prepared by said map picture preparing device on said display panel;
a photo data storage device to store first photo data taken by satellite photography or air photography and showing a limited surface area of the earth;
a photo picture preparing device that reads second photo data regarding a current position of one'"'"'s own based on current position information indicating the current position of the one from said photo data storage device, and prepares a photo picture showing a periphery of the current position of the one based on the second photo data and a second coefficient of composition, β
, such that the photo picture includes second photo data only within the periphery of the current position of the one;
a position judging device that judges whether the one is within the area based on the current position information; and
a photo picture display device that overlays the photo picture on a corresponding area of the map picture for display on said display panel when said position judging device judges that the one is within the area, and displays a current position mark on the displayed photo picture;
wherein when said position judging device judges that the one is within the area, the one is automatically notified of entering into the area by said photo picture display device changing a displayed color of the current position mark on the displayed photo picture as an indicator of being within the area.
