ABSTRACT:
A plurality of infrared-light-emitting areas are displayed in a display screen of a liquid crystal display apparatus in a method that allows each of the infrared-light-emitting areas to be distinguished. Then, an image in a direction of a pointed position is captured by an operating device. Based on a result of distinguishing each of the infrared-light-emitting areas and a position of each of the infrared-light-emitting areas, a pointed position on the display screen is calculated. This makes it possible to properly detect the pointed position on the display screen pointed by the operating device, regardless of (i) a distance between the operating device and the display apparatus and (ii) a rotation angle of the operating device around an axis in an image capture direction of the operating device.
