Abstract: A single-ended blur detection probe and method with a local sharpness map for analyzing a video image sequence uses two sets of edge filters, one for “fast edges” and the other for “slow edges.” Each set of edge filters includes a horizontal bandpass filter, a vertical bandpass filter and a pair of orthogonal diagonal filters where the frequency response of the fast edge filters overlap the frequency response of the slow edge filters. The video image sequence is input to each filter of each set, and the output absolute values are combined with weighting factors to produce a slow edge weighted sum array and a fast edge weighted sum arra. The respective weighted sum arrays are then decimated to produce a slow edge decimated array and a fast edge decimated array.

Abstract: In a noise reducer, a first subtractor 101 generates a difference N1 between an input video signal Ynow and a delayed video signal Ypre output from a frame memory 104 and obtained by delaying an output video signal Yout by a time corresponding to one screen. An amplitude adjuster 102 adjusts the amplitude of an output signal of the first subtractor 101 based on a motion signal MV. A second subtractor 103 subtracts an output N2 of the amplitude adjuster 102 from the input video signal Ynow. A motion detector 2 calculates the amount of change in the input video signal Ynow with respect to the delayed video signal Ypre for each of pixels constituting one screen, and generates, as the motion signal MV, a signal determining, as “moving,” a predetermined proportion of pixels for which the amount of change is smaller than a predetermined threshold value.
