Abstract
Abstract Apparatus is provided for insetting one image optically into a portion of another image. The apparatus includes two separate image generation and projection systems. A beam splitter combines the two images for projection onto a single viewing screen. One image projection system includes a field lens having one surface comprising an electroplastic film. A cathode ray is caused to sweep those portions of the film which represent the portion to be insetted by the other image. A TV camera system controls the generation of the cathode beam in response to an image projected through the beam splitter onto the TV camera. The portions of the film struck by the beam effectively occult corresponding portions of one image. The other image occupies the occulted portion.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
178 words
An optical insetting system wherein one optical image is inset into another optical image, said system comprising a first image generator and a second image generator, a projection screen, means for projecting a first image along a first image projection path from said first generator onto said screen, means for projecting a second image along a second image projection path onto said screen, an electro-optical element in said first projection path so arranged that said first image passes therethrough, a television camera, means for transmitting a portion of the light comprising said second image to said television camera, means for generating an electron beam, means for causing said electron beam to scan said electro-optical element in synchronism with the scanning of said second image by said television camera, and means connecting the output from said television camera to said beam generating means to control the generation of said beam so that said electro-optical element occults that portion of said first image which corresponds to the second image so that said second image is inset into said first image.
Claim 2
Dependent Claim
178 words
An optical insetting system wherein one optical image is inset into another optical image, said system comprising a first image generator and a second image generator, a projection screen, means for projecting a first image along a first image projection path from said first generator onto said screen, means for projecting a second image along a second image projection path onto said screen, an electro-optical element in said first projection path so arranged that said first image passes therethrough, a television camera, means for transmitting a portion of the light comprising said second image to said television camera, means for generating an electron beam, means for causing said electron beam to scan said electro-optical element in synchronism with the scanning of said second image by said television camera, and means connecting the output from said television camera to said beam generating means to control the generation of said beam so that said electro-optical element occults that portion of said first image which corresponds to the second image so that said second image is inset into said first image.
Claim 3
Dependent Claim
115 words
An optical insetting system wherein an optical image is inset into another optical image, said system comprising a first image generator and a second image generator, a screen upon which both images are projected, means for projecting the images generated by said first and second image generators onto said screen, a selectively controlled light valve interposed between said first image generator and said screen, first means for receiving a projection of the image generated by said second image generator, and second means under the control of said first means for causing said light valve selectively to occult the portion of saiD first image which corresponds to the position said second image occupies on said screen.
Claim 4
Dependent Claim
115 words
An optical insetting system wherein an optical image is inset into another optical image, said system comprising a first image generator and a second image generator, a screen upon which both images are projected, means for projecting the images generated by said first and second image generators onto said screen, a selectively controlled light valve interposed between said first image generator and said screen, first means for receiving a projection of the image generated by said second image generator, and second means under the control of said first means for causing said light valve selectively to occult the portion of saiD first image which corresponds to the position said second image occupies on said screen.
Claim 5
Dependent Claim
32 words
The system defined in claim 2 wherein said second means comprises an electron gun for generating a beam of electrons and means for deflecting said generated beam to traverse said electro-optical element.
Claim 6
Dependent Claim
43 words
The system defined in claim 3 wherein said electro-optical element comprises a material whose optical transmission characteristics are temporarily modified by the local application of electricity thereto, the characteristics of said material being modified only at the points where said electricity is applied.
Claim 7
Dependent Claim
43 words
The system defined in claim 4 wherein said first means comprises a photosensitive device which generates electrical signals proportional to the point-by-point intensity of light projected upon it, and means for scanning said device to recover the electrical signals on a point-by-point basis.
Claim 8
Dependent Claim
67 words
The system defined in claim 5 wherein said means for deflecting said generated beam and said means for scanning said device are synchronized so that said device and said element are scanned together, and further including means for connecting the electrical signal output from said device to said electron gun so that said beam of electrons is generated in accordance with the signals generated by said device.
Claim 9
Dependent Claim
44 words
The system defined in claim 6 further including a beam splitter arranged to transmit some of the image generated by said second image generator to said electro-optical device and to transmit some of the image generated by said second image generator to said screen.
