Abstract:
A method of processing digital data representing a series of sequential images at a first resolution, the method comprising:examining digital data representing at least two sequential images at said first resolution to identify at least one image region which has substantially the same luminance intensity in each of said at least two sequential images, image segments corresponding to at least one image region identified by said examining being identified image segments, image segments corresponding to image regions that are not identified by said examining being non-identified image segments; processing the digital data corresponding to the first of said at least two sequential images to produce a set of reference data, the set of reference data including data representing an identified image segment at a resolution which is different than the resolution at which non-identified image segments of said first of said at least two sequential images are represented by said set of reference data; and using the set of reference data to perform a motion compensated prediction operation.
