Image motion vector detecting apparatus

摘要

An image motion vector detecting apparatus includes a low-pass filter (12, 12 min ) for suppressing a spatial high frequency component of an image signal in one or both of the horizontal and vertical directions, and a high-pass filter (13) for suppressing a spatial low frequency component of an image signal in one or both of the horizontal and vertical directions. Using an image signal which has passed through the filters, a correlation value for discrete shifts is obtained through a matching operation. Based on the obtained correlation values, a correlation value for continuous shifts is estimated through interpolation processing. A shift having a minimum correlation value is calculated to detect an image motion vector.
