<p>PURPOSE:To detect a moving vector with high accuracy in the unit of picture elements or below by detecting an optimum moving position in the unit of picture elements and detecting the optimum moving position based on the result of detection and the result of comparison between a reproduced moving picture and a current moving picture. CONSTITUTION:A minimum value of result of comparison DADD with respect to a current moving picture when a one preceding frame reproduced moving picture is moved sequentially in the unit of picture elements is detected by an arithmetic processing circuit 9. Thus, the moving position formed with a picture most similar to the current moving picture while the one preceding frame reproduced moving picture is moved sequentially in the unit of picture elements is detected in the unit of picture elements. Moreover, a sum data DADD smaller next to the minimum value is detected from the comparison result DADD and the direction of the optimum moving position is detected. Moreover, the arithmetic processing is executed based on 3 sum data DADD values y0, y1 and y-1. Thus, the optimum moving position is detected with accuracy in the unit of picture elements or below and the moving vector is detected with high accuracy.</p> |
