Abstract
The average value of sensitivities in each of the image areas (m×n) recognized as a subject is calculated. If the average value of sensitivities is greater than the threshold value, the transmission voltage to the ultrasonic probe is limited according to the difference between the average value of sensitivities and the threshold value.
