Patent No. 5017143 

Method and apparatus for producing subliminal images (Backus, et al., May 21, 1991)

ASSIGNEE: Popeil Industries, Inc., Beverly Hills, CA

Abstract

A method and apparatus to produce more effective visual subliminal communications. Graphic and/or text images, presented for durations of less than a video frame, at organized rhythmic intervals, the rhythmic intervals intended to affect user receptivity, moods or behavior. Subliminal graphic images having translucent visual values locally dependent on background values in order to maintain desired levels of visual contrast.

Notes:

SUMMARY OF THE INVENTION

The present invention is directed to a method and apparatus for producing more effective visual subliminal images. To that end, graphic and/or text images may be presented during a single video frame refresh, at organized rhythmic intervals intended to affect user receptivity, moods or behavior. Such images may have translucent or opaque visual values that are locally dependent on local background values in order to maintain desired levels of visual contrast.

Objects and Advantages

Accordingly, it is an object of the present invention to display visual subliminal images which convey information quickly and unambiguously.

A further object is to present visual subliminal images which are not dependent on the literacy or reading ability of a viewer.

A further object is to increase the number of visual subliminal messages which may be shown a viewer within a given period of time.

A further object is to increase the effectiveness of visual subliminal messages by organizing their presentation rhythms to alter viewer moods or behavior, or enhance viewer receptivity.

A further object is to increase the variety of scenes which may be used as effective backgrounds for visual subliminal messages.

A further object is to increase allowable visual contrast of subliminal messages with their backgrounds by reducing subliminal message appearance time.

Readers will find further objects and advantages of the invention from a consideration of the ensuing description of the preferred embodiment and the accompanying drawings.

-----------------------------------------------------------------

There are several ways to produce the preferred embodiment's subliminal images. One of these is to use a video editing studio. Here a tape containing the clearly perceptible images 22 to be used as background for the preferred embodiment's subliminal images 24 26 28 is modified using video animation equipment to isolate each video frame. An artist using a video frame editor adds the preferred embodiment's subliminal images 24 26 28 to each selected frame. Once all the subliminal messages are added, the master tape is duplicated to other VCR tapes.

Home or business users may then play the duplicate tapes back on VCRs for television viewing of both the clearly perceptible and subliminal images.

Many variations of this preferred embodiment may easily be envisioned by someone skilled in the art. As examples:

Any combination of features from the above could be used without others being present.

Instead of using a VCR tape duplicated from a studio master, other media could be used.

Also, the subliminal and background images could emanate locally from separate sources while in use. This would mean using a local video image combiner and possibly electronically monitoring the local visual values of the background images to determine the local subliminal image contrast values.

The subliminal images could have chroma and use color and/or color saturation to generate local frame contrast.

The subliminal image could be presented on raster systems having more than two interlaced fields per video frame. In this case, subliminal image rasters would be omitted which represented one or more refresh fields.

Successive identical subliminal images could be shown with only image shift being used to keep them from becoming perceptible through overlap.

Subliminal images could be animated by presenting changing subliminal images representing movement in adjoining or closely proximate video frames or fields. Each such animated frame could have some or all of the preferred embodiment's features.

Subliminal messages could be presented serially like the old Berma Shave road signs. Here individual frames would present words, phrases or graphic symbols which only make sense when linked together. An example of this is two proximate subliminal messages, the first saying "THIN" and the second saying "IS HEALTHY".

Also, the same subliminal message could be repeated several times within the sam video frame.

While embodiments and applications of this invention have been shown and described, it would be apparent to those skilled in the art that many more modifications are possible without departure from the inventive concepts herein. The invention, therefore, is not to be restricted except in the spirit of the appended claims.
