Application 07/918,519
bit quantization level) than the stored image, a higher
resolution image is reconstructed from two of the stored
images. See also Appellants’ figure 6. This is performed by
adjusting one of the images to be of the same spatial
resolution as the second image and then combining the images.
Appellants identify on page 20 of the specification that if
the images are of equal spatial resolution, the step of
combining the images can be performed by averaging.
Independent claim 9 is illustrative of the invention.
9. Apparatus for reconstructing an image with additional
quantization levels of signal resolution from two quantized
non-dependent representations of the image at the spatial
resolution of one of the representations, comprising:
means for converting one of the quantized non-dependent
representations to the same spatial resolution as the other
representation; and
means for combining the converted and non-converted
representations to form a combined representation with
additional quantization levels of signal resolution.
