Abstract
A dual display device for displaying an input image includes first and second displays. The first display is arranged for modulating an image from the second display. The dual display device further includes a processor having an image splitter which splits the input image into illumination and reflection images according to a retinex algorithm. The reflection image is displayed on the first display and the illumination image is displayed on the second display. Due to the series arrangement of the two displays, the input image is substantially recreated. The illumination image typically is a spatially low-resolution image derived from the input image.
