ABSTRACT:
An ultrasound imaging device having functions of storing data of at least one image in a memory and reading the data from the memory to show a freeze-frame on a display in response to a freeze instruction given by a user includes a discerning signal generation unit for generating a discerning signal which marks a change from one image frame to a next image frame in a video signal of ultrasound images, a discerning signal adding unit for marking a point of the change in the video signal by adding the discerning signal to the video signal, a control unit for stopping image data of the video signal from being stored in the memory after receiving the freeze instruction at a moment when the discerning signal is detected in the video signal, so that last two fields of the video signal stored in the memory and forming the freeze-frame are an even field and an odd field of the same frame.
