Patent Images
1. A method of decompressing a series of still digital images comprising:
- using a processor to perform the steps of;
reading a first digital image from a series of digital images stored in a single file, wherein said single file contains said first digital image of said series of digital images and difference information related to at least one more digital images of said series of digital images;
storing said first digital image in a first output file; and
for each subsequent digital image of said at least one more digital images stored in said single file;
combining difference information related to said each subsequent digital image from said series of digital images with said first digital image creating a next digital image;
storing said next digital image in a next output file.

Abstract
The present invention is directed to a method and apparatus for encoding a series of still images. The first image is captured and stored, then for each subsequent image of the series, that image is captured and compared to the first image or the previous image and difference information between the first or previous image and each subsequent image of the series is stored, resulting in one output file that contains the base image and difference information for each subsequent image, thereby reducing the amount of storage needed to store a series of images.
