| 20090317010 | Multiple Resolution Image Storage - In accordance with one or more aspects, multiple folders are generated each corresponding to one of multiple levels of an image pyramid, and each of the multiple levels including one or more tiles. In each of the multiple folders, one or more files are stored, each file including image data for a tile of the level corresponding to the folder. In accordance with other aspects, a first version of an image is generated, the first version of the image having a lower resolution than the image. The image is compressed using a first compression process, and the first version of the image is compressed using a second compression process, the second compression process being a higher quality process than the first compression process. Both the compressed image and the compressed first version of the image are stored as an image pyramid for the image. | 12-24-2009 |
| 20090317020 | Variable Resolution Images - 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. | 12-24-2009 |
| 20100171759 | MULTI-LAYER IMAGE COMPOSITION WITH INTERMEDIATE BLENDING RESOLUTIONS - Providing high frame rate image rendering using multiple image layers per frame. A plurality of image layers having different resolutions are arranged in order of increasing resolution. Beginning with the image layer having the lowest resolution, the image layer is upsampled to a resolution of a next image layer having a higher resolution. The upsampled image layer is blended with the next image layer. The upsampling and blending continues for each of the image layers to produce a blended image. The blended image is provided for display as a frame of video. Aspects of the invention produce a high-resolution composite image during animated navigation across zoom and pan states. | 07-08-2010 |
| 20100226593 | SCALABLE MUTABLE TILED MULTI-RESOLUTION TEXTURE ATLASES - Functionality for storing and modifying multi-resolution texture atlases is provided so that applications can expose methods to enable users to access and browse a collection that includes multiple multi-resolution images. The images are stored as thumbnails in a texture atlas having different levels of detail in which the levels are arranged in an image pyramid that includes multiple tiles that are each stored as separate files. The thumbnails are spatially storable as textures in the texture atlas using a fractal layout (which in one illustrative example is a Morton layout) that enables images to be efficiently packed in the tiles. The fractal layout ensures that no more than one tile stores less than a fully packed texture at each level of detail. The same packing order scales across each level of detail in the texture atlas so that layout information is stored for the individual images in the collection only once. | 09-09-2010 |
| 20100325573 | INTEGRATING DIGITAL BOOK AND ZOOM INTERFACE DISPLAYS - In accordance with one or more aspects, different pages of a digital book are displayed in each of two display areas of a device using a book display model. In response to a request to semantically zoom out, the digital book is displayed in a broader context, the broader context using a context display model rather than the book display model. In response to additional requests to semantically zoom out, the digital book is displayed in increasingly broader contexts. Additionally, in response to requests to semantically zoom in, the digital book is displayed in increasingly narrower contexts until the digital book is displayed in the book display model rather than the context display model. | 12-23-2010 |
| 20110304625 | ADAPTIVE IMAGE RENDERING AND USE OF IMPOSTER - Images and/or collections of images may be rendered in a way that adapts to ambient circumstances, and that may enhance a user's perception of experience quality. When an image is requested for display, it is determined whether a rendered version of the image exists. If no rendered version of the image exists, then an imposter image is displayed. The imposter image may include arbitrary colors and/or patterns. If an appropriate rendered version of the image exists, then the rendered version may be displayed in place of the imposter version. While the imposter or rendered image is being displayed, the image may be retrieved, and may be rendered at other resolutions (e.g., successively higher resolutions). The choice of resolutions may be adapted to available transmission bandwidth, display speed, or other considerations. | 12-15-2011 |
| 20120039547 | VARIABLE RESOLUTION IMAGES - 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. | 02-16-2012 |
