PURPOSE:To easily detect the misinput of a visual line direction at the time of inputting the data by displaying a map on a part of a display screen, inputting the visual line direction of a three-dimensional display image on the map and executing the three-dimensional coordinate conversion of the input visual line direction so as to visually easily catch it. CONSTITUTION:A map 112 for inputting a visual line direction is displayed on a part of a display screen 11 for displaying a three-dimensional display image 111, visual line direction information is found out based on the coordinate information of a position inputted to the map 112. The three-dimensional coordinate conversion of the displaying three-dimensional display image 111 is executed based on the visual line direction information. Since the map 112 is displayed on a part of the display screen 11 and the visual line direction of the three- dimensional display image is inputted on the map, the input visual line direction can be visually easily catched. Consequently, the misinput of the visual line direction can be easily detected at the time of its input. |
