<p>An object to be examined is scanned with an ultrasonic wave and a tomographic image of the object is obtained on the basis of reflected ultrasonic waves. This image is stored in a frame memory. The types of the motion of the image, i.e., a still image, a motion image and a slight motion are detected on the basis of the difference in image data between the current tomographic image and a past tomographic image, and the correlation between rasters of the current tomographic image. The correlation coefficient used for frame correlation processing between the current tomographic image and the past tomographic image is adaptively changed in accordance with the detection result. <IMAGE></p> |
