First Claim
Patent Images
1. A method comprising:
- compressing an image sequence based on a plurality of foveation zones, wherein a first foveation zone of the plurality of foveation zones corresponds to a first view location and a second foveation zone of the plurality of foveation zones corresponds to a second view location, and wherein during a portion of the image sequence, the first and second view locations occur concurrently.

Abstract
A scene of an image sequence is compressed using a number of foveation zones, each foveation zone being weighted based on a probability of a viewer looking at a corresponding portion of the first scene. Another scene of the image sequence is compressed using a different number of foveation zones, each foveation zone being weighted based on a probability of a viewer looking at a corresponding portion of the second scene.
