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.

Claims

1-18. -18. (canceled)

19. A method of decompressing a series of still digital images comprising:

reading a first digital image from a series of digital images stored in a single file;

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 a 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.

20. The method of decompressing a series of still digital images of claim 19 wherein said single file is located in a file on a hard disk.

21. The method of decompressing a series of still digital images of claim 19 wherein said first output file is stored in a hard disk.

22. The method of decompressing a series of still digital images of claim 19 wherein said single file is located in a temporary memory.

23. The method of decompressing a series of still digital images of claim 19 wherein said single file is located in a memory card.

24. The method of decompressing a series of still digital images of claim 19 further comprising closing said next output file.

25. The method of decompressing a series of still digital images of claim 22 further comprising:

closing said next output file and copying said next output file from said temporary memory to a memory card.
