PARALLAX IMAGE AUTHORING AND VIEWING IN DIGITAL MEDIA

摘要

An authoring tool assigns a first depth value to a first image layer and a second depth value to a second image layer. The first depth value is a first simulated distance from a user. The second depth value is a second simulated distance from the user. The authoring tool composes an image based on the first image layer and the second image layer such that the image is displayed within a page in a scrollable area on a viewing device. The first depth value is utilized to generate a first offset value from a first static position of the first image layer and the second depth value is utilized to generate a second offset value from a second static position of the second image layer based upon a scroll position of the page with respect to a target location in the scrollable area to create a parallax effect.
