<P>PROBLEM TO BE SOLVED: To accurately perform viewpoint movements in dynamic image display. <P>SOLUTION: Data of dynamic images have a hierarchical structure made of a zero layer 30, a first layer 32, a second layer 34, and a third layer 36 in the z-axis direction from the top to the bottom of the illustration. Each of the layers is configured by dynamic image data of a dynamic image shown with a different resolution, that is, multiple image frames arranged in a time-sequence. A viewpoint coordinate at the time of dynamic image display and a display region corresponding to the viewpoint coordinate are decided by a virtual three-dimensional space defined by the x-axis to show the longitudinal direction of the image, the y-axis to show the vertical direction, and the z-axis to show the resolution. By providing a switching boundary of layers in relation to the z-axis, the layers of the dynamic data used for frame drawing are switched according to the value of z on the frame coordinate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
