Variable resolution images
First Claim
Patent Images
1. A computing device comprising:
- a display device;
one or more computer-readable storage media;
a variable resolution image display module embodied on the one or more computer readable storage media and configured to obtain and display variable resolution images on the display device,individual variable resolution images being defined by at least one image pyramid,said one image pyramid including multiple levels, each level comprising a portion that is at a different resolution than a portion of another of the levels,individual levels being separated into different numbers of tiles, wherein one tile at a first of the levels corresponds to multiple tiles at a second of the levels,wherein each level comprises a different version of a same image, wherein the variable resolution image display module is configured to select an image for display at a resolution that is closest to a resolution associated with the display device,wherein the variable resolution image display module is configured to retrieve variable resolution images that are stored in a manner in which each level of the image pyramid has corresponding image data stored in a different folder, each folder including one or more files, each file including image data for a tile at the corresponding level.

Abstract
In accordance with one or more aspects, a variable resolution image is displayed at an initial resolution. The variable resolution image has multiple portions, at least two of which have different resolutions. A request to display one of the multiple portions of the variable resolution image at a higher resolution is received, and a check is made as to whether a higher resolution version of the one portion is available. The higher resolution version of the one portion is displayed if available, otherwise the one portion at the initial resolution is displayed.

1. A computing device comprising:
-
a display device; one or more computer-readable storage media; a variable resolution image display module embodied on the one or more computer readable storage media and configured to obtain and display variable resolution images on the display device, individual variable resolution images being defined by at least one image pyramid, said one image pyramid including multiple levels, each level comprising a portion that is at a different resolution than a portion of another of the levels, individual levels being separated into different numbers of tiles, wherein one tile at a first of the levels corresponds to multiple tiles at a second of the levels, wherein each level comprises a different version of a same image, wherein the variable resolution image display module is configured to select an image for display at a resolution that is closest to a resolution associated with the display device, wherein the variable resolution image display module is configured to retrieve variable resolution images that are stored in a manner in which each level of the image pyramid has corresponding image data stored in a different folder, each folder including one or more files, each file including image data for a tile at the corresponding level. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A system comprising:
-
one or more computer storage media; at least one variable resolution image stored on the one or more computer-readable storage media and being defined by multiple image pyramids, each image pyramid including multiple levels, each level comprising at least a portion that is at a different resolution than at least a portion of another of the levels, individual levels being separated into different numbers of tiles, wherein one tile at a first of the levels corresponds to multiple tiles at a second of the levels, each level of an image pyramid corresponding to a same image, wherein one portion of one of the pyramids corresponds to one portion of another of the pyramids, a variable resolution image display module embodied on the one or more computer storage media and being configured to select an image for display at a resolution that is closest to a resolution associated with a display device, wherein the variable resolution image display module is configured to retrieve variable resolution images that are stored in a manner in which each level of the image pyramid has corresponding image data stored in a different folder, each folder including one or more files, each file including image data for a tile at the corresponding level. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
