IMAGE FILE GENERATION DEVICE, IMAGE PROCESSING DEVICE, IMAGE FILE GENERATION METHOD, AND IMAGE PROCESSING METHOD

摘要

An image hierarchy generation unit (120) of a controller (100b) reads image data stored in a hard disk drive (50) and generates and hierarchizes images having a plurality of resolutions. An image segmentation unit (122) segments images in respective hierarchies into tile images. A redundancy detection unit (124) analyzes the images in the respective hierarchies and detects redundancies of the images in the same hierarchy and between different hierarchies. A tile image reference table creation unit (126) creates a tile image reference table, in which region numbers and tile numbers are associated with each other, in consideration of the redundancies. An image file generation unit (128) generates an image file to be finally outputted, which includes image data and the tile image reference table.
