Abstract:
A data divider divides N-dimensional digital image signals into higher-order bit signals and lower-order bit signals. Reference values corresponding to all combinations of the divided higher-order bit signals are divisionally stored in 2N−1 sub-memories without overlaps. The (N+1) reference values necessary for interpolation processing are read by a reference value reader at the same time.
