Claim 0:
1. A method of applying a plurality of disparate digital image processing filter operations to image data, the method comprising:
partitioning the image data into one or more partitions; and
for each partition of the image data:
applying a first digital image processing filtering operation to the partition of the image data to generate one of first filtered image data and first delta data comprising a difference between the image data and the first filtered image data;
applying a second digital image processing filtering operation to the partition of the image data to generate one of second filtered image data and second delta data comprising a difference between the image data and the second filtered image data;
combining the outputs of the first and second filtering operations for the partition to generate combined filtered image data by, for each partition of image data;
if the first filtering operation generates first filtered image data, calculating first delta data as the difference between the image data and the first filtered image data;
if the second filtering operation generates second filtered image data, calculating second delta data as the difference between the image data and the second filtered image data; and
summing the image data, the first delta data, and the second delta data; and

clipping the combined filtered image data for the partition.
