A data processing method for the ultrasonic diagnostic apparatus, according to the present invention includes: acquiring data corresponding to the same predetermined depth, out of a plurality of pieces of ultrasonic data acquired by performing the plurality of times of ultrasonic transmitting/receiving operations in the same sound ray direction and at predetermined time intervals filtering the acquired data corresponding to the same predetermined depth, and extracting echo data from a moving part in a body acquiring the first autocorrelation amplitude value when this echo data is delayed by a first predetermined time period acquiring the second autocorrelation amplitude value when the above-described echo data is delayed by a second predetermined time period and further relating the multiplied value obtained by multiplying the first autocorrelation amplitude value by the second autocorrelation amplitude value, to the luminance of a predetermined hue.
