Abstract:
1. An image display device having a function of controlling a backlight luminance, comprising: a display panel including a plurality of display elements; a backlight including a plurality of light sources; an emission luminance calculation section configured to divide an input image into a plurality of areas and obtaining luminances upon emission of light sources corresponding to each area as first emission luminances on the basis of a portion of the input image of a corresponding area; an emission luminance correction section configured to obtain second emission luminances by correcting the first emission luminances in accordance with a selected correction mode which is selected from among a plurality of correction modes; a display data calculation section configured to obtain display data for controlling light transmittances of the display elements, on the basis of the input image and the second emission luminances; a panel driver circuit configured to output signals for controlling the light transmittances of the display elements to the display panel, on the basis of the display data; and a backlight driver circuit configured to output signals for controlling luminances of the light sources to the backlight, on the basis of the second emission luminances.
