Zusammenfassung:	Techniques described herein convert a plurality of digital images into an image or images more amenable to data compression. In one embodiment, an ordered collection of input digital images is provided. A first digital image from the ordered collection is identified as a base image, and an empty image strip is formed. For each second digital image from the ordered collection, and upon a condition in which the second image is the base image, the base image is appended to the image strip. Upon a condition in which the second image is not the base image, a difference image is computed from the base image and the second image and appended to the difference image to the image strip. Quantization and conventional image compression may be applied to the image strip to produce a compressed image strip.
