Abstract

A security X-ray screening system comprises an X-ray scanner that scans an individual and produces an image signal. An image processor connected to the X-ray scanner receives the image signal and processes the image signal to produce a distorted image of the individual. In one embodiment the image processor stretches, elongates, and/or re-sizes sections of the image signal and produces the distorted image of the individual.

Claims

1. An X-ray screening apparatus for security screening an individual, comprising:

an X-ray scanner that scans the individual and produces an image signal,

an image processor connected to said X-ray scanner that receives said image signal, and

at least one processor that processes said image signal and produces a distorted image of the individual.

2. The X-ray screening apparatus for security screening an individual of claim 1 wherein said at least one processor processes said image signal and produces an image of the individual that has acceptable distortion.

3. The X-ray screening apparatus for security screening an individual of claim 1 wherein said at least one processor processes said image signal and produces an image of the individual that has gross distortion.

4. The X-ray screening apparatus for security screening an individual of claim 1 wherein said image signal embodies an image of the individual and wherein said at least one processor includes a processor that receives said image signal and process said image signal by stretching sections of said image and producing said distorted image of the individual.

5. The X-ray screening apparatus for security screening an individual of claim 1 wherein said image signal embodies an image of the individual and wherein said at least one processor includes a processor that receives said image signal and process said image signal by elongating sections of said image and producing said distorted image of the individual.

6. The X-ray screening apparatus for security screening an individual of claim 1 wherein said image signal embodies an image of the individual and wherein said at least one processor includes a processor that receives said image signal and process said image signal by resizing sections of said image and producing said distorted image of the individual.

7. The X-ray screening apparatus for security screening an individual of claim 1 wherein said image signal embodies an image of the individual and wherein said at least one processor includes a processor that receives said image signal and process said image signal by stretching sections of said image or elongating sections of said image or resizing sections of said image and producing said distorted image of the individual.

8. The X-ray screening apparatus for security screening an individual of claim 1 wherein said image signal embodies an image of the individual and wherein said at least one processor includes a processor that receives said image signal, identifies constant points of said image, and uses said constant points to stretch, elongate, or re-size sections of said image and produce said distorted image of the individual.

9. The X-ray screening apparatus for security screening an individual of claim 1 wherein said image signal embodies an image of the individual and wherein said at least one processor includes a processor that receives said image signal, identifies constant points as the top-most, bottom-most, and side points of said image, and uses said constant points to stretch, elongate, or re-size sections of said image signal and produce said distorted image of the individual.

10. The X-ray screening apparatus for security screening an individual of claim 1 including an image viewing screen connected to said at least one processor.

11. The X-ray screening apparatus for security screening an individual of claim 1 including image recording equipment connected to said at least one processor.

12. The X-ray screening apparatus for security screening an individual of claim 1 wherein said image signal embodies an image of the individual and wherein said at least one processor includes a processor that receives said image signal, identifies constant points of said image, and uses said constant points to stretch, elongate, or re-size sections of said image and produce said distorted image of the individual and wherein said at least one processor includes an adjustment processor that provides variable degrees of distortion of said image.

13. A method of security X-ray screening an individual, comprising the steps of:

scanning the individual and producing an image signal representing the individual,

processing said image signal to produce a distorted image of the individual, and

visually displaying said distorted image.

14. The method of security X-ray screening an individual of claim 13 wherein said step of processing said image signal to produce a distorted image of the individual comprises processing said image signal to produce an image of the individual that has acceptable distortion.

15. The method of security X-ray screening an individual of claim 13 wherein said step of processing said image signal to produce a distorted image of the individual comprises processing said image signal to produce an image of the individual that has gross distortion.

16. The method of security X-ray screening an individual of claim 13 wherein said image signal embodies an image of the individual and wherein said step of processing said image signal to produce a distorted image of the individual comprises stretching sections of said image.

17. The method of security X-ray screening an individual of claim 13 wherein said image signal embodies an image of the individual and wherein said step of processing said image signal to produce a distorted image of the individual comprises elongating sections of said image.

18. The method of security X-ray screening an individual of claim 13 wherein said image signal embodies an image of the individual and wherein said step of processing said image signal to produce a distorted image of the individual comprises resizing sections of said image.

19. A security X-ray screening method of claim 13 wherein said image signal embodies an image of the individual and wherein said step of producing a distorted image of the individual comprises identifying constant points of said image, and using said constant points to stretch or elongate or re-size sections of said image to produce a distorted image of the individual.

20. A security X-ray screening method of claim 19 wherein said steps of identifying constant points of said image, and using said constant points to stretch or elongate or re-size sections of said image to produce a distorted image of the individual comprises identifying constant points as the top most, bottom-most, and side points of said image.

21. A security X-ray screening method of claim 19 wherein said steps of identifying constant points of said image, and using said constant points for stretching or elongating or re-sizing sections of said image to produce a distorted image of the individual comprises adjusting said stretching or said elongating or said re-sizing sections of said image to produce an image of the individual that has acceptable distortion.

22. A security X-ray screening method of claim 19 wherein said steps of identifying constant points of said image, and using said constant points for stretching or elongating or re-sizing sections of said image to produce a distorted image of the individual comprises adjusting said stretching or said elongating or said re-sizing sections of said image to produce an image of the individual that has gross distortion.
