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 the amount of source light emitted from a light source. The image display device includes a source light amount control device and an image correction device. The source light amount control device determines the amount of source light and then controls the amount of source light. The image correction device corrects a signal used for changing saturations of the image data so as to reduce a change in the saturations due to a change in the amount of source light, the change in the amount of source light being performed by the light source amount control device.
