Abstract:
1. An image display device that corrects image data, which are used for displaying an image, using a gray scale value assigned to each pixel and that also controls a source light luminance of a light source, comprising: an image processing engine including the first and second time characteristics are calculated independently from each other, the time characteristic control section executes filtering on the source light luminance for each frame using the first time characteristic as a filter coefficient and executes filtering on the image correction amount for each frame using the second time characteristic as a filter coefficient, and the time characteristic control section executes filtering on the source light luminance for each frame on the basis of the first time characteristic, calculates an image correction amount for each frame using the source light luminance that is filtered on the basis of the first time characteristic, and executes filtering on the calculated image correction amount on the basis of the second time characteristic.
