Method and apparatus for recognizing gesture of image display device

Abstract

An image display device capable of providing a realistic interface by increasing a response speed of a gesture recognition by reducing the amount of calculation, and a method for controlling an operation thereof are disclosed. The method for controlling an operation of an image display device includes: capturing a first image by using a camera and extracting depth data from the captured first image; detecting a first object by using a peak value from the depth data extracted from the first image; capturing a second image by using the camera and extracting depth data from the captured second image; detecting a second object by using a peak value from the depth data extracted from the second image; and designating the second object as an interested object based on the distance between the first and second objects.
