DEFINITION

Classification: 353/90

(under subclass 89) Subject matter including means to gradually increase the intensity of an image (i.e., fade in) or to gradually diminish the intensity of an image until it is no longer recognizable (i.e., fade out).

(1) Note. When one picture is being faded in and the other is faded out at the same time both pictures are at least partially on the screen at the same time. This is not considered a composite image, however, since the various parts must cooperate to form such an image as defined in subclass 30 about.
