MOVING VECTOR DETECTION APPARATUS |
摘要 |
A motion vector detecting apparatus comprises image receiving part for receiving image signals of two consecutive frames in terms of time; subtracting circuit for obtaining a difference of value of picture element at corresponding positions between the two frames; absolute value circuit for obtaining a residual difference which is an absolute value of signal which is output from the subtracting circuit; solution vector detecting circuit for dividing the image signal into a plurality of blocks and processing the image signal and for summing the residual difference for every block and for obtaining solution vector of the block with one-picture-element-pitch accuracy from a minimum value of the sum value; predicting circuit for predicting an extremal value of a half-picture-element pitch in each of plural directions by interpolating by using the residual differences in the vicinity of the solution vector of the one-picture-element pitch; developing a correction value circuit for detecting a minimum value of the extremal values and developing a correction value corresponding to the minimum value; and developing a vector circuit for developing an output vector which is equal to the solution of the one-picture-element pitch added by the correction value. <IMAGE> |
