Abstract
A video encoder according to the present invention improves coding efficiency of a super high definition video by setting an area of MB size and optimally determining size of the area. A locally decoded image (a) is subjected to frequency analysis in a frequency analyzing unit. Based on the result, an area setting unit sets a local area in a picture to which the maximum MB size is applied. An area boundary correcting unit corrects an area boundary in accordance with a representative motion characteristic, and an N-value calculating unit determines the maximum MB size (N×N) of each area based on a result of encoding a neighboring picture. The area setting and the N-value calculation are performed step by step.
