Method of eliminating black banding occurring in the process of

Abstract

A method of eliminating black banding occurring along the boundary line of an exterior information signal image and a pictorial original image in the process of recording compound information includes control of the luminance intensity of a scanning reproducing device immediately prior to and/or immediately following external information transfer thereby onto the photosensitive receiving surface. Such control provides gradual, timed increase of the luminance intensity of the device immediately prior to normal activation thereof, and/or gradual, timed decrease of the luminance intensity of the device immediately following normal deactivation thereof, so as to predeterminately merge the compounded images and thereby eliminate the black banding phenomenon.
