Disclosed herein are an ultrasonic apparatus, which substitutes a frame image having a large motion blur factor and being currently displayed with a frame image having a small motion blur factor and obtained prior to a select instruction input time to display the substituted image when a select instruction for selecting the frame image being displayed or a substitute image display instruction is input, and a method for controlling the same. The ultrasonic apparatus includes an image processor to generate a plurality of frame images based on ultrasonic signals, a display to sequentially display the plurality of frame images, an input device to receive a select instruction for selecting a frame image being displayed on the display among the plurality of frame images； and a controller to control the display to display at least one of frame images, each of which has a motion blur factor equal to or less than a predetermined threshold value and is obtained prior to the select instruction input time, among the plurality of frame images when a motion blur factor of the frame image selected by the select instruction exceeds the threshold value or a substitute image display instruction is input.
