摘要： 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.

摘要： Provided are image display apparatus and image display methods capable of suitably making correction for variation of driving conditions due to an electric resistance of matrix wiring of a display panel by downsized hardware. The apparatus and methods involve a device of calculating voltage drop amounts caused by the resistance of row wires, for input image data, and a device of calculating image data with correction for the voltage drop amounts (corrected image data). An overflow processing circuit is provided so as to prevent overflow of the image data after the correction from an input range of a modulator, and the overflow is prevented by a gain. Since a gradation converter for changing a gradation conversion characteristic by a gain is provided in the stage preceding to the configuration for making the correction for influence of the voltage drop, it becomes feasible to cancel saturation characteristics of phosphors and to display images with high quality thereby.
