In a moving picture encoding method and a moving picture encoding apparatus of the present invention, after calculating an absolute value of a difference for every corresponding pixel data between continuous two frames, an interframe difference calculation means calculates an average value per frame and an average value per scene of the absolute value of the difference, and a scene change determination means determines that a scene change has occurred, when the average value per frame is more than or equal to a predetermined number times as large as the average value per scene, and in case that the scene change is detected by the scene change determination means a frame type change means changes a frame type so that interframe predictive coding is not conducted.
