Provided is a moving picture processing method which prevents degradation of subjective image quality caused by a motion of a moving picture. The moving picture processing method includes the following steps: a motion compensation step (S116) of shifting a noise indicated by a stored noise signal (FMN) according to a motion of a moving picture indicated by an input image signal (VIN), by performing motion compensation on the stored noise signal (FMN) that is used for superimposition on a picture indicated by an input image signal (VIN) and is stored in a noise frame memory (102); and a superimposition step (S120) of superimposing the shifted noise, as a superimposition noise signal SN, onto a current picture to be processed which is indicated by an input image signal (VIN) and is a moving picture that appears after the motion has occurred.
