Abstract
An image display device corrects image data, which are used for displaying an image, using a gray scale value assigned to each pixel and also controls a source light luminance of a light source. The image display device includes a scene change detection device, an image correction device, a source light luminance control device, and a time characteristic control device. The scene change detection device detects a change of scene of the input image data. The image correction device corrects the image data. The source light luminance control device controls the source light luminance. The time characteristic control device changes a first time characteristic of a change in the source light luminance and a second time characteristic of an image correction amount by which the image data are corrected on the basis of the change of scene and executes a process on the basis of the first time characteristic and the second time characteristic.
