WIPO Patent Application WO/2013/005371

A1

Constructed images (221a, 221b), which are combined to create a display image, are divided into tiled images, and are compressed for each tiled image according to different compression formats (S12). The constructed images (221a, 221b) are each reduced in size (S14), and divided into tiled images and compressed according to each compression format (S16). Two constructed images (222) are combined and then reduced in size (S18), and divided into tiled images and compressed (S20). An image (224) is reduced in size and the uppermost layer of an image (226) is generated (S22), and said image is divided into tiled images and similarly compressed (S24). Among the hierarchical data generated in this manner, for the hierarchy of a data group 230, and a data group 228 having a subhierarchy, a plurality of compressed data (for example, data 236) for tiled images representing the same region are consolidated and treated as data for a single tiled image.
