1. An ultrasound diagnostic apparatus comprising:
a probe configured to transmit ultrasound signals to an object and receive ultrasound echo signals reflected from the object;
a display module;
an input device;
a storage; and
a controller configured to:
obtain color doppler signals based on processing of the echo signals,
obtain a plurality of color doppler image frames each having a color-mapped area based on the color doppler signals,
store the plurality of color doppler image frames in the storage, and control the display module to sequentially display the plurality of color doppler image frames,
wherein the controller is further configured to:
in response to receiving an image freeze command through the input device, determine a recommended color doppler image frame from the plurality of color doppler image frames based on a color mapping value corresponding to a size of the color-mapped area in each of the plurality of color doppler image frames,
control the display module to display the recommended color doppler image frame as a freeze image, determine the recommended color doppler image frame among a reference number of color doppler image frames obtained before or after receiving the image freeze command, and
determine one of the reference number of color doppler image frames which has a highest color mapping value as the recommended color doppler image frame.
