Abstract
A method of displaying an image using an image display device in which the image display device has an artificial light source includes inputting primary image signals to the image display device, determining chroma state of the primary image signals for each image frame, and determining gray-scale state of the primary image signals for each image frame. The primary image signals are transformed to multi-color image signals and luminance of the artificial light source is controlled, in response to the determined chroma state and gray-scale state of the primary image signals.
