1. An ultrasonic image processing method for extracting, from an ultrasonic moving image including an object moving periodically, an amount of movement of the moving image other than movement of the object in the ultrasonic moving image, comprising:
dividing the input ultrasonic moving image in a time period equal to a movement cycle of the object, and extracting an outline of the object from each of a plurality of frames of the ultrasonic moving image in each time period of a plurality of consecutive time periods to acquire time-series data representing movement of the outline in the time period; and
acquiring time-series comparison data representing a difference in movement of the outline in every time period based on a difference between the time-series data in two adjacent time periods.
