US Patent:

6418240, Jul 9, 2002

Filed:

Dec 3, 1997

Appl. No.:

08/984450

Inventors:

Raymond Yu - Fremont CA

Assignee:

Alaris Inc. - Fremont CA

International Classification:

G06K 936

US Classification:

382232, 382236, 3484301

Abstract:

A method and apparatus for performing multiple frame image compression and decompression of motion video data are provided. In one embodiment, a plurality of sequential frames in a motion video sequence are collected and digitally filtered as a single image. At least some of the results of the digital filtering are then encoded to generate compressed data. In another embodiment, a plurality of sequential frames are filtered as if the boundary of each frame is adjacent to a boundary in the same spatial location of another of the plurality of sequential frames.
