Abstract
Abstract Progressive changes in a given subject undergoing processes of modification and alteration are illustrated by simultaneously displaying a plurality of video signals on a video monitor for visual comparison. At least one video signal containing information for creating at least one reference display of the given subject is recorded. The video monitor is activated to display the reference display. At least another video signal is generated containing information for creating at least one comparison display of the given subject, the comparison display presenting the given subject at times different from the reference display. The video monitor is activated to display the at least one comparison display whereby the reference and comparison displays are produced simultaneously on the video monitor for visual comparison.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
138 words
A method for comparative analysis wherein a plurality of pictorial scenes are simultaneously displayed on the screen of a video monitor for comparison, comprising the steps of: recording at least one video signal containing information for creating at least one reference pictorial scene of a given subject; activating the video monitor screen for separately displaying said at least one reference pictorial scene; generating video information for creating at least one comparison pictorial screne of said given subject, said at least one comparison pictorial scene presenting said given subject at times different from said at least one reference pictorial scene; and activating the video monitor screen for separately displaying said at least one comparison pictorial scene whereby said reference and comparison pictorial scenes are produced separately and simultaneously on the video monitor screen for comparison of said given subject.
Claim 2
Independent Claim
138 words
A method for comparative analysis wherein a plurality of pictorial scenes are simultaneously displayed on the screen of a video monitor for comparison, comprising the steps of: recording at least one video signal containing information for creating at least one reference pictorial scene of a given subject; activating the video monitor screen for separately displaying said at least one reference pictorial scene; generating video information for creating at least one comparison pictorial screne of said given subject, said at least one comparison pictorial scene presenting said given subject at times different from said at least one reference pictorial scene; and activating the video monitor screen for separately displaying said at least one comparison pictorial scene whereby said reference and comparison pictorial scenes are produced separately and simultaneously on the video monitor screen for comparison of said given subject.
Claim 3
Dependent Claim
124 words
The method described in claim 1 wherein said step of activating the video monitor screen for displaying said at least one reference display includes the steps of: connecting the recorded video signal of said at least one reference pictorial scene of a given subject to a video multiplex unit, said unit having a multiplicity of inputs for video signals and having one composite video output signal whereby the input video signals including said recorded video signal are combined in a predetermined synchronized time sequence to produce said one composite video output signal; and connecting said one composite video output signal for said video multiplex unit to said video monitor whereby said video monitor is activated for displaying said at least one reference pictorial scene.
Claim 4
Dependent Claim
110 words
The method described in claim 2 wherein said step of activating the video monitor screen for displaying said at least one comparison pictorial scene includes the steps of connecting the generated video information of said at least one comparison pictorial scene of said given subject to one of said multiplicity of inputs whereby the comparison video information is combined in a predetermined synchronized time sequence with said recorded video signal of said at least one reference pictorial scene to form said video multiplex unit composite output signal to activate said video monitor for displaying said at least one comparison pictorial scene along with said at least one reference pictorial scene.
Claim 5
Independent Claim
132 words
A method for illustrating progressive changes in a given subject upon which a process of alteration and modification is applied wherein a video special effects generator combines first and second pictorial scenes of the subject generated before and after the process, respectively, for simultaneous display on a video monitor comprising the steps of: recording the first pictorial scene of the given subject before the application of the process; generating the second pictorial scene of the given subject after the application of the process; combining said first and second pictorial scenes sequentially in time in the video special effects generator for simultaneous adjacent pictorial display on the video monitor of the given subject before and after the process; and comparing the simultaneous pictorial displays for visually illustrating the changes in a given subject.
Claim 6
Independent Claim
132 words
A method for illustrating progressive changes in a given subject upon which a process of alteration and modification is applied wherein a video special effects generator combines first and second pictorial scenes of the subject generated before and after the process, respectively, for simultaneous display on a video monitor comprising the steps of: recording the first pictorial scene of the given subject before the application of the process; generating the second pictorial scene of the given subject after the application of the process; combining said first and second pictorial scenes sequentially in time in the video special effects generator for simultaneous adjacent pictorial display on the video monitor of the given subject before and after the process; and comparing the simultaneous pictorial displays for visually illustrating the changes in a given subject.
