A rotation axis and a rotation angle for display are calculated and stored in the three-dimensional display viewpoint candidate storage unit V2.

As shown in the screen example of FIG. 18, the movement of the viewpoint rotates about an intermediate direction between the directions in which the two targets travel, and in a direction perpendicular thereto (the side on which the first priority target travels). . In the example of the screen of FIG. 18, JAL113 and ANA234 are the two targets in the sub-display screen area. In the sub-display area where the dotted line is the intermediate axis that is the basis of rotation, the main display screen area is enlarged and displayed so that the center is the touch coordinate point.

The magnification is stored in the three-dimensional magnification storage unit V3. If no enlargement is required, set this enlargement ratio to 1
And

In the three-dimensional display information generation unit V4, when the enlargement ratio is smaller than the enlargement ratio for making the height 1000 pixels, the three-dimensional display information generation unit V4 does not perform the processing, and
