In an image display device performing area-active drive, reduced power consumption is achieved without causing a flaw in displaying when performing a partial display. A display position information acquisition unit (101) outputs display position specification data specifying a display position on screen. An LED output value calculation unit (102) partitions an input image into a plurality of areas, and obtains LED data which are data for the luminescence brightness level of an LED for each area. At that time, on the basis of the display position specification data, the luminescence brightness level of an LED for an area not to be displayed is set to 0. A display brightness level calculation unit (103), on the basis of the luminescence brightness level, obtains a display brightness level for each area. A partial display-use correction filter generation unit (105), on the basis of the display position specification data, generates a correction filter for partial display-use correction filter (106) storing data for correction corresponding to each pixel. An LCD data calculation unit (107), on the basis of the input image, the display brightness level, and the data for correction, obtains liquid crystal data. |
