Image file generation device, image processing device, image file generation method, and image processing method

摘要

An image hierarchy generation unit reads image data stored in a hard disk drive, generate images with a plurality of resolutions, and hierarchizes the images. An image dividing unit divides the image in each layer into tile images. A redundancy detection unit analyzes the image in each layer so as to detect redundancy between images within the same layer or images from different layers. A tile image reference table creates a tile image reference table that maps area numbers to tile numbers, in view of the redundancy. An image file generation unit creates an image file that should be ultimately output and includes image data and the tile image reference table.
