<p><P>PROBLEM TO BE SOLVED: To provide an image display device in which an image showing the inner side of a point of gaze is easily displayed, when a user performs a pitch angle change operation on a view point. <P>SOLUTION: A virtual space display part 86 displays an image showing an appearance seen, by looking toward a view line direction from the view point inside a virtual space. A view point moving part 110 executes, according to the user's view point moving operation, at least one of moving a view point position and changing the view line direction. A pitch angle change center point position calculating part 92 calculates the position of a pitch angle change center point present on a line, extending from the view point toward the view-line direction. A pitch angle change part 114 changes, according to the user's pitch angle change operation, the view point around the pitch angle change center point by using a pitch angle, and changes the view line direction so that the view line direction points toward the pitch angle change center point from the view point position obtained, after the pitch angle is changed. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
