Image display system
View Patent ↗An image display system is disclosed that enables users to navigate very large digital images quickly and seamlessly. The system is optimized to transmit image data from a disk drive at high data rates. The image data is stored on the disk drive in a file format optimized for high speed retrieval, display, and seamless navigation. The image display system can be cascaded for showing two or more contiguous images.
1. A method of storing an image on a storage device in a tiled format, comprising:
formatting the storage device to include a block size that is an integer multiple of a tile size, wherein the tile size corresponds to a display output;
reading pixel data of a source image;
generating, from the read pixel data, a first tile and a second tile, wherein the first tile and the second tile each have overlapping portions that overlap by an adjustable amount, and the overlapping portions include substantially identical pixel data;
storing the first tile and the second tile on the storage device; and
repeating the reading, generating, and storing a plurality of times to store the image,
wherein the image is stored on the storage device as a contiguous string of data.
2. The method of claim 1 , wherein the image is a geographic image.
3. The method of claim 1 , wherein the image is stored in a file having a predetermined format.
4. The method of claim 1 , wherein the adjustable amount of overlap comprises at least an amount substantially equal to a height and width of the display output.
5. The method of claim 1 , wherein the source image is stored over two or more files.
6. The method of claim 5 , wherein the two or more files are stored on a single storage device.
