Abstract
In an image display device and method, a moving picture is composed in a graphics generator with a still picture and graphics to obtain a composite image. A moving picture area, a still picture area and a graphics area of the composite image are specified and detected as binary detection signals. The detection signals are composed with one another in levels corresponding to the drawing areas to generate a composite detection signal. On the basis of the composite detection signal, the contrast, the luminance signal and the speed modulation signal are controlled for the drawing areas of a moving picture, a still picture and graphics. When the video signals of the moving picture plane and the non-moving picture planes are composed with one another and the composite image is displayed, the optimum image quality can be achieved in each of the moving picture and the non-moving picture areas of the composite image.
