Image display system
View Patent ↗A method of configuring an image for data storage on a storage device in an overlapping-tiled format and a method of displaying a desired image selected for viewing on a display are disclosed. The method of configuring an image for data storage includes formatting an image to include a plurality of image tiles, each image tile in the plurality of image tiles having at least a portion that is substantially identical to at least a portion of an adjacent image tile in the plurality of image tiles. The method further includes converting data of the image from data in a first color space into data in a second color space so as to reduce a size of the data of the image, and storing the image data in the second color space.
1. A method of displaying a desired image selected for viewing on a display device, comprising:
receiving an instruction to display on the display device the desired image, the desired image being a portion of an image tile in a plurality of image tiles of a master image, each image tile in the plurality of image tiles having at least a portion that is substantially identical to at least a portion of an adjacent image tile in the plurality of image tiles;
determining a location of the desired image within the plurality of tiles;
reading data corresponding to the image tile where the desired image is located from a storage device;
converting the data corresponding to the image tile comprising the desired image from a first color space into data in a second color space; and
displaying data in the second color space corresponding to the desired image on the display device.
2. The method according to claim 1 , wherein converting the data corresponding to the tile comprising the desired image from the first color space into data in the second color space comprises converting the data from a YUV 4:2:2 color space into data in a RGB color space.
3. The method according to claim 2 , wherein the data in the RGB color space comprises 24 bit-pixels and the data in the YUV 4:2:2 color space comprises pixels having, on an average, 16 bits per pixel.
4. The method according to claim 2 , further comprising displaying data in the RGB color space corresponding to the desired image on the display device.
5. The method according to claim 1 , wherein determining the location of the desired image within the plurality of tiles comprises determining which image tile in the plurality of tiles contains the desired image.
6. The method according to claim 1 , wherein reading the data corresponding to the image tile where the desired image is located from the storage device comprises reading one or more blocks of data corresponding to the image tile where the desired image is located from the storage device, wherein each image tile in the plurality of image tiles is stored in the storage device as a plurality of blocks of data and a size of each image tile is an integer multiple of a block size of the storage device.
7. A computer system configured to display a desired image on a display device, the computer system comprising one or more processors configured to:
receive an instruction to display on the display device the desired image, the desired image being a portion of an image tile in a plurality of image tiles of a master image, each image tile in the plurality of image tiles having at least a portion that is substantially identical to at least a portion of an adjacent image tile in the plurality of image tiles;
determine a location of the desired image within the plurality of tiles;
read data corresponding to the image tile where the desired image is located from a storage device in communication with the one or more processors;
convert the data corresponding to the image tile comprising the desired image from a first color space into data in a second color space; and
display data in the second color space corresponding to the desired image on the display device.
8. The computer system according to claim 7 , wherein the one or more processors are configured to convert the data from a YUV 4:2:2 color space into data in a RGB color space.
9. The computer system according to claim 8 , wherein the data in the RUB color space comprises 24 bit-pixels and the data in the YUV 4:2:2 color space comprises pixels having, on an average, 16 bits per pixel.
10. The computer system according to claim 8 , wherein the one or more processors are configured to display data in the RGB color space corresponding to the desired image on the display device.
11. The computer system according to claim 7 , wherein the one or more processors are configured to determine which image tile in the plurality of tiles contains the desired image.
12. The computer system according to claim 7 , wherein the one or more processors are configured to read one or more blocks of data corresponding to the image tile where the desired image is located from the storage device, wherein each image tile in the plurality of image tiles is stored in the storage device as a plurality of blocks of data and a size of each image tile is an integer multiple of a block size of the storage device.
