TECHNIQUES FOR ZOOMING IN AND OUT WITH DYNAMIC CONTENT

摘要

Methods and apparatuses for providing a zoom experience. A snapshot of content is generated in response to detection of initiation of a zoom control input. A zoom operation is performed based on the zoom control input on the snapshot to provide a post-zoom snapshot. The snapshot is displayed while performing the zooming. The content is rendered to provide an amount of zoom as indicated by the zoom control input to provide a post-zoom rendering. The post-zoom is blended with the snapshot and the post-zoom rendering to provide a final image. The final image is displayed.
