Abstract: A map display apparatus is disclosed, which includes a display for display of a 3D map on a map display screen and a controller for displaying the 3D map in first or second 3D state, and switches a display state of the 3D map from the first 3D state to the second 3D state in response to satisfaction of a predetermined switching condition in the first 3D state. In the first 3D state, a road is drawn in an upper/lower direction of the map display screen and front view object images, each being is an image of an object facing onto the road and viewed from the road, are arranged facing onto the road. In the second 3D state, at least some of the front view object images are rotated more toward position of being perpendicular to a line of sight e than in the first 3D state.

Abstract: An image display system has an operating device, a specifying device and an image display device. If the operating device receives a single operation from an exterior (i.e., from user), the operating device outputs first and second signals based on the single operation. The specifying device specifies a viewpoint and a sight line direction to look down a picture based on the first and second signals outputted by the operating device. The image display device displays an image of the picture in such a manner that the picture is looked down from the viewpoint in the sight line direction specified by the specifying device. As a result, the operation for adjusting the viewpoint and the sight line direction is facilitated.
