wherein the at least one processor is further configured to determine a predicted moving point of the cursor in the image based on an input start point and a moving direction of the user input received from the external input device in the image, and move the cursor to a position of the at least one object neighboring the predicted moving point in the image, and

wherein the at least one image processor forms an ellipse having the third point as a focus and selects the one of the plurality of objects, the plurality of objects being included in the ellipse, from among the plurality of objects within the radius range.

13. The display apparatus of claim 12, wherein a major axis of the ellipse is positioned on an axis in the moving direction of the cursor.

15. A control method of controlling a display apparatus, the method comprising:

displaying an image including at least one object and a cursor;

receiving user input comprising an input start point and an input end point in the image from the external input device;

determining a predicted moving point of the cursor based on the input start point and a moving direction and a moving distance of the user input in the image; and

moving the cursor to a position of the at least one object neighboring the predicted moving point in the image,

wherein the moving distance is a distance between the input start point and the input end point.

16. The control method of claim 15, wherein the determining comprises calculating a coordinate of the predicted moving point of the cursor in the image based on the moving distance of the cursor between a first input of the input start point and a second input of the input end point and the moving direction of the cursor between the first input and the second input.
