Kind Code:

A1

Abstract:

Video data is given a layered structure comprising, in the z-axis direction from the top toward the bottom of the drawing, a zeroth layer (30), a first layer (32), a second layer (34), and a third layer (36). Each layer is constituted by video data in which a single video image is represented by different resolutions, in other words, by data in which multiple image frames are arranged in a time series. When a video is displayed, viewpoint coordinates and display area corresponding thereto are defined by a virtual 3D space comprising the x-axis, which represents the horizontal direction of an image, the y-axis, which represents the vertical direction, and the z-axis, which represents the resolution. By providing switching boundaries for the layers in relation to the z-axis, the video data layer used for rendering a frame is switched according to the z value of the coordinates of the frame.
