An image processing system includes: an image capture device operable to
capture at least first and second images of an object at different
exposures, a storage for at least part of the at least first and second
images, a filter for splitting the at least first and second images into
respective first and second spatial frequency components, the first
frequency component being of lower frequency than the second, a selector
for selecting local image intensity data from the second spatial
frequency components of a region of the at least first and second images
for combination with the first frequency component from the corresponding
region of the first image, and a combiner for combining the selected
local image data from the second spatial frequency components of the at
least first and second images with the first spatial frequency component
of the first image to form a final image.
