Title: Movement detector
Inventor: WECKENBROCK HERMANN J
IPC: H04N5/21
Filed: 1987-01-16
Abstract: A motion detector is provided for detecting interimage motion represented by video signals. For composite video signals, the detector analyses both the chrominance and luminance components for image motion. Interimage motion represented by the luminance component is determined from interimage signal differences. The interimage signal differences (10,20) are separated into high (50,22) and low (22) frequency spectra corresponding to fine and coarse luminance image detail. Selected signal differences from the low frequency spectrum are summed (62) and threshold detected (64) to determine motion in the coarse image detail. The high frequency spectrum of the sample differences are applied to parallel summing circuits (72,76,74,78) which sum different combinations of sample differences in order to discriminate (80,82) motion signals from non-moving chrominance transitions. The detection signals from the high and low frequency motion detectors are combined (86) to produce a luminance motion signal. Interimage motion represented by the chrominance component is detected by combining selected ones of interimage signal sums. The interimage signal sums are high pass filtered and applied to parallel combining elements which discriminate chrominance motion from vertical luminance transitions.
