  • Patent number: 6580466
    Abstract: A method for generating a series of images for playback on at least a portion of a display, each image in the series being imperceptibly different from an immediate preceding different image in the series, methods for displaying such images, systems for generating and/or displaying the images and media carrying such images. The images are generated such that each subsequent different image in the image series is different from a prior image by an image difference determined prior to generation of the subsequent corresponding portion of an image. The image series is displayed with such timing that an ordinary viewer cannot perceive the transitions or differences between adjacent or successive images over at least a 5 second interval, yet over time, the displayed scene will progress so that at widely disparate points in time, the displayed images can be perceptibly different, i.e., the scene can be noticeably different.
