Summary:A motion vector detecting device includes: a motion predicting and compensating circuit calculating cost values of a plurality of motion vectors, which is candidates of an optimal motion vector, using a cost function indicating an encoding efficiency with a first pixel precision every prediction mode and calculating the optimal motion vector with a second pixel precision and the cost value of the optimal motion vector with the second pixel precision using a profile of the cost values with the first pixel precision.
