ABSTRACT:
A method is disclosed for compressing a set of digital images to achieve an average compressed data rate over the entire set. A subset of images are selected from the set of images. A threshold viewing distance and a desired average compressed data rate are specified, and compression parameters are determined from the threshold viewing distance. The subset of images is compressed with the compression parameters to produce compressed data, and an average compressed data rate is calculated for the compressed data from the subset of images. The average compressed data rate for the subset of images is compared to the desired average data rate. If the average compressed data rate for the subset of images is less than or equal to the desired average compressed data rate, remaining images from the image sequence that are not in the subset of images are compressed using the compression parameters that were used for the subset of images. Otherwise, the threshold viewing distance is modified to a larger distance and the compression process is repeated.
