Abstract: Provided is an image display apparatus. The apparatus includes a tuner, a demodulator, a demultiplexer, a controller, an OSD controller, a graphic driver, and an OSD displayer. The tuner receives broadcasting signals, the demodulator demodulates signals of a channel selected by the tuner, and the demultiplexer demultiplexes signals demodulated by the demodulator into audio signals, video signals, and a PSIP table. The controller controls information of an electronic program guide extracted from the demultiplexed data to be output in the form of an on-screen-display, and divides the electronic program guide into a text region and a background region to set gradation on the background region of the electronic program guide. The OSD controller performs a gradation process with respect to the background region of the electronic program guide using a gradation value set by the controller. The graphic driver allows the electronic program guide on which the gradation process is performed by the on-screen-display controller to be displayed as an image in the form of the on-screen-display. The on-screen-display displayer displays the on-screen-display representing the electronic program guide delivered from the graphic driver on a screen together with decoded image signals.
