Abstract
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.
