Method and apparatus for forming three-dimensional moving image

PURPOSE: A method and an apparatus for forming three-dimensional moving pictures are provided to increase a frame rate of a live three-dimensional image which is finally displayed, thereby realizing more natural three-dimensional moving pictures without increasing load of calculation of a live three-dimensional image forming device. CONSTITUTION: A probe(302) transmits ultrasonic wave signals to an object and receives the ultrasonic wave signals reflected from the object. A three-dimensional raw data obtaining unit(304) of an image processor(310) obtains raw data from the received ultrasonic wave signals. An enhanced live three-dimensional imaging unit(306) of the image processor generates a plurality of image frames from the obtained raw data. The enhanced live three-dimensional imaging unit generates a plurality of virtual frames to be inserted between the plurality of image frames. The enhanced live three-dimensional imaging unit renders a three-dimensional image of the object by using the plurality of image frames and the plurality of virtual frames.
