METHOD AND APPARATUS FOR RECOGNIZING GESTURE OF IMAGE DISPLAY DEVICE
First Claim
1. A method for controlling an operation of an image display device, the method comprising:
- 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.

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.

13. An image display device comprising:
-
a camera configured to capture a first image and a second image following the first image; and a controller configured to extract depth data from each of the captured first and second images, detect first and second objects each having a peak value from each of the extracted depth data, and designate the second object as an interested object based on the distance between the first and second objects.
