Animated graphic image generation and coding
First Claim
Patent Images
1. A method for generating and coding for transmission an animated graphic image, comprising the steps of:
- composing a first frame of the image from a plurality of component objects from a predetermined set of object types, the composition including scaling and location of each object within a fixed coordinate set image field;
coding the first frame as an ordered rendering list of the component objects, the rendering list identifying the order in which the component objects are to be rendered on regeneration of the image;
sequentially coding each subsequent frame (n) as a number of animation command words representing respective animation transforms between the frame (n) and a previous frame (n−
n1).

Abstract
A method for generating and coding animated graphic images for transmission to hand-held or mobile devices uses an object-component technique wherein images are composed from a limited set of component types, particularly points and polygons. An initial frame is defined as a list of objects to be displayed. Subsequent frames are encoded as a list of changes to the objects to the previous frame.
