The present invention relates to three-dimensional glasses, to a three-dimensional image display apparatus, and to a method for driving the three-dimensional glasses and the three-dimensional image display apparatus. The present invention is a method for driving three-dimensional glasses for watching a three-dimensional image consisting of a left-eye image and a right-eye image, wherein the method comprises the following steps: transmitting glasses characteristic information, including information relating to the opening/closing speed of shutters of a left-eye lens unit and a right-eye lens unit of the three-dimensional glasses, to an external three-dimensional image display apparatus for outputting the three-dimensional image; receiving synchronization information, including information relating to the output periods of the left-eye image and right-eye image, from the three-dimensional image display apparatus; and synchronizing, using the synchronization information, the opening/closing periods of the shutters of the left-eye lens unit and the right-eye lens unit with the output periods of the left-eye image and right-eye image outputted by the three-dimensional image display apparatus. The synchronization information includes information on the time of opening the shutter of the left-eye lens unit, information on the time of closing the shutter of the left-eye lens unit, and information on modes for indicating the type of image outputted by the three-dimensional image display apparatus, and the method for driving the three-dimensional glasses and three-dimensional image display apparatus of the present invention, efficient data communication between the three-dimensional glasses and the three-dimensional image display apparatus is enabled, in order to increase the convenience of a user watching the three-dimensional images and prevent the unnecessary consumption of a battery of the three-dimensional glasses.

Three-dimensional glasses, three-dimensional image display apparatus, and method for driving the three-dimensional glasses and the three-dimensional image display apparatus

According to an embodiment of the present invention, a method for operating an image display device using a pointing device includes receiving, from the pointing device, a first signal and a second signal to display a pointer at a particular location on a screen of the image display device, wherein the first signal initiates displaying of the pointer in accordance with a first input selection of the pointing device, determining whether coordinates corresponding to the second signal to display the pointer are outside an active area, wherein the active area is greater than an actual size of the screen, and resetting the coordinates to new coordinates corresponding to a pre-designated area of the screen and displaying the pointer at the pre-designated area of the screen when the coordinates are determined to be outside the active area.

Image display apparatus and method for operating the same

A method and apparatus are provided for updating thumbnail images in a thumbnail list. A plurality of thumbnail images may be generated based on television channels. A thumbnail list including a portion or all of the plurality of the generated thumbnail images may be provided for output to a display. The thumbnail list may be updated such that an image of at least one thumbnail image is changed. A frequency of change in the image of the at least one thumbnail image is greater than other thumbnail images in the thumbnail list during a prescribed time period. The updated thumbnail list may be provided for output to a display.
