Claim 5:
6. An ultrasound diagnostic apparatus comprising:
at least one processor which when executing a program configures the processor to:
detect a lesion included in an ultrasonic image which is a real-time video image, and that outputs lesion information when the lesion is detected; and
cause a mark for indicating the lesion to be displayed on the ultrasonic image based on the lesion information, and restrict display of the mark when a mark display restriction condition is satisfied by a continued detection of the lesion; and
judge that the mark display restriction condition is satisfied, based on the lesion information,
wherein the lesion information includes position information which shows a position of the lesion, and size information which shows a size of the lesion,
wherein the at least one processor is further configured to judge that the mark display restriction condition is satisfied, based on at least one of the position information and the size information of the lesion,
wherein a mark display condition includes a first condition and a second condition, the first condition being a condition of determining that the lesion is continued to be detected over m or more frames, where m is an integer greater than or equal to 2, the second condition being is a condition of determining that an amount of movement of a center coordinate of the lesion between a reference frame and a current frame is within a first range, and the mark can be displayed when both of the first and second conditions have been met, and
wherein the mark display restriction condition includes a third condition, a fourth condition, and a fifth condition, the third condition being a condition of determining that detection of the lesion is continued over n frames, where n is an integer greater than or equal to m, the fourth condition is a condition of determining that the amount of movement of the center coordinate of the lesion between the reference frame and the current frame is within a second range, the fifth condition being a condition of determining that the amount of change of the size of the lesion between the reference frame and the current frame is within a third range, and when all of the third, fourth and fifth conditions are simultaneously satisfied, the mark is not displayed on the screen.
