An ultrasound diagnostic apparatus includes: a transducer array; a transmission circuit transmitting an ultrasonic beam from the transducer array; a reception circuit obtaining fundamental component data based on reception signals corresponding to the fundamental component of an ultrasonic wave and harmonic component data based on reception signals corresponding to a harmonic component of the ultrasonic wave; and an image producer performing frame correlation processing on the fundamental component data and the harmonic component data generated for each frame so as to produce an ultrasound image. The frame correlation processing is performed such that the weight of harmonic component data of another frame used in the frame correlation processing of the harmonic component data is greater than the weight of fundamental component data of another frame used in the frame correlation processing of the fundamental component data. |
