Abstract
A total of 2 N-1 serially connected delay circuits sequentially delay a digital image signal, where N is a positive integer, and a total of N-1 adders each respectively add a pair of delayed signals output from (N.+-.k)-th ones of the 2 N-1 delay circuits, where k is an arbitrary positive integer such that k<N, while a selector is responsible for a boost frequency to select an output signal of one of the N-1 adders. A first multiplier multiplies the selected signal by a first coefficient, a second multiplier multiplies an output signal of an N-th one of the 2 N-1 delay circutis by a second coefficient, and another adder synthesizes output signals of the first and second multipliers.
