    摘要： A method for viewpoint selection assistance in free viewpoint video generation includes: executing acquisition processing that includes acquiring three-dimensional information with respect to a subject on a field by using a plurality of cameras placed around the field; executing first identification processing that includes identifying a path of a ball for a predetermined period based on the three-dimensional information; executing second identification processing that includes identifying at least one player located within a predetermined distance from a position of the ball for a predetermined duration of time or longer in the predetermined period; executing setting processing that includes setting, as a video output range, a range containing both of the path of the ball and a path of the at least one player; and executing generation processing that includes generating video for the range set by the setting processing.

    摘要： The invention provides a method for generating multilayer images. The method comprises receiving three-dimensional, 3D, source data of a scene and generating a plurality of layers at different depths in a virtual 3D scene, wherein each layer corresponds to a particular layer depth value relative to an origin point. Image data is generated for each layer based on the 3D source data, wherein the image data comprises texture data and transparency data, and displacement maps are generated for the layers based on the 3D source data and the depth values of the layers. The displacement maps define the depth of different points on a corresponding layer relative to the layer depth, wherein the generation of the displacement maps is restricted such that a depth surface, as defined by any displacement map, does not intersect any other depth surface in the virtual 3D scene. A depth surface is defined as the mapping of a displacement map onto the corresponding layer.
