To provide an image display device having a liquid crystal panel or another display unit to display compressed video data including MPEG data, in which the display quality of the liquid crystal panel is enhanced without additional reference frame memory, an image display device that can be included in, for example, a mobile telephone and a PDA decodes compressed video data including MPEG data and displays them on a display panel, such as a liquid crystal panel. The image display device includes an LAO processing section, in which frame data to be displayed is corrected to enhance the display quality of the display panel. This correction is performed by changing the level of frame data based on a difference value, for example, between current frame data and previous frame data. This process in the LAO processing section and the decoding process of the compressed video data share a reference frame memory to reference the previous frame data, thus eliminating the need for an additional frame memory.
