<p>PROBLEM TO BE SOLVED: To provide an area division method for image coding where areas can be integrated with a high coding efficiency even in the case that objects are overlapped with each other. SOLUTION: A motion vector of a current frame picture for each small area is detected based on a current frame picture and a preceding frame picture so as to discriminate each small area of the current frame picture to be an intra-area suitable for intra coding or an inter-area suitable for inter coding based on the current frame picture and the preceding frame picture. In the case that two small areas adjacent to each other are discriminated to be both the intra area, the areas are integrated, and in the case that two small areas adjacent to each other are not discriminated to be both the intra area, whether or not a difference between motion vectors of both the areas is a prescribed threshold value or below is discriminated, and an area integration processing section 3 integrates the areas only when the difference between the motion vectors of both the areas is a prescribed threshold value or below.</p> |
