The lapse time measurement part measures lapse time from carry out of the operation to the ultrasonic diagnostic apparatus to receipt of the contact. The setting part selects a region of interest to be operated from a plurality of regions of interest displayed on the touch panel, on the basis of a photographing mode and the lapse time determined by the determination part. The change part changes the region of interest selected as an operation target by the selection part, on the basis of the received contact to the touch panel. |
