Abstract
An image display device includes a gain calculator, a multiplier and an overdrive unit. The gain calculator calculates a ratio 'Gmax0/Gmax1' as gain, with respect to each segmented region of liquid crystal panel. The symbol 'Gmax1' represents a maximum gradation in one frame period of an image signal to be supplied to each segmented region. The symbol “Gmax0” represents a maximum gradation to be determined depending on the number of bits in the image signal. The multiplier multiplies an image signal subjected to frame frequency conversion in a frame frequency conversion unit by the gain to generate an image signal subjected to the area control processing, with respect to each segmented region. The overdrive unit emphasizes the image signal subjected to the area control processing, using an image signal generated by delaying the image signal subjected to the area control processing for one frame period.
