Abstract: In an image display apparatus, image data on which gradation conversion for compensating phosphor saturation has been carried out by a gradation convertor (200) undergoes voltage drop compensation and then amplitude regulation using a gain (Gd) before being fed to modulating means (8). Here, the gradation convertor (200) changes its conversion characteristic (the region of a compensation table it uses) in accordance with the value of the gain (Gd). As a result it is possible to compensate the affects of phosphor saturation characteristics and voltage drop and an excellent image can be displayed.

Abstract: Driving condition is determined so that the stimulating values of brightness with respect to drive data become closer to being regular in interval. As the drive condition, the frequency of a reference clock used for the pulse width modulation is changed to be higher than the range of high gradations in the range of low gradations in drive data. Accordingly, smaller increment in brightness in the range of low gradation and larger increment in the range of high gradations are achieved.
