Claims
- 1. A method for designing a lens system comprising:
relaxing a first design tolerance for said lens system, said first design tolerance specifying an allowed aberration in a raw image produced through said lens system, said allowed aberration capable of being corrected by an image correction processor; and enhancing a lens system characteristic that would have been limited by a less relaxed first design tolerance.
- 2. A method for designing a lens system comprising:
relaxing a first design tolerance for said lens system, said first design tolerance specifying an allowable amount of f-theta deviation in a raw image produced through said lens system, said allowable amount of f-theta deviation capable of being corrected by an image correction processor; and enhancing a lens system characteristic that would have been limited by a less relaxed first design tolerance.
- 3. A lens system designed in accordance with the method of claim 1.
- 4. An image capture system equipped with the lens system of claim 3, and configured to capture said raw image.
- 5. An image correction processor configured to correct said allowed aberration from at least a portion of said raw image captured through the lens system of claim 3.
- 6. The image correction processor of claim 5 wherein said raw image is corrected to generate a corrected image having less of said allowed aberration than that in said raw image.
- 7. The image correction processor of claim 5 wherein a portion of said raw image is corrected to generate a view being substantially free of said allowed aberration.
- 8. The image correction processor of claim 5 further comprising a general-purpose programmed computer configured to correct said allowed aberration in said portion.
- 9. The image correction processor of claim 5 further comprising a specialized circuitry configured to correct said allowed aberration in said portion.
- 10. A lens system designed in accordance with the method of claim 2.
- 11. An image capture system equipped with the lens system of claim 10, and configured to capture said raw image.
- 12. An image correction processor configured to correct said allowed aberration from at least a portion of said raw image captured through the lens system of claim 10.
- 13. The image correction processor of claim 12 wherein said raw image is corrected to generate a corrected image having less of said allowed aberration than that in said raw image.
- 14. The image correction processor of claim 12 wherein a portion of said raw image is corrected to generate a view being substantially free of said allowed aberration.
- 15. The image correction processor of claim 12 further comprising a general-purpose programmed computer configured to correct said allowed aberration in said portion.
- 16. The image correction processor of claim 12 further comprising a specialized circuitry configured to correct said allowed aberration in said portion.
- 17. A method comprising steps of:
capturing a raw image having an allowed aberration through a lens system having a first design tolerance that has been relaxed to cause said allowed aberration and to enhance a lens system characteristic; correcting, by an image correction processor, said allowed aberration in at least a portion of said raw image resulting in a corrected image; and presenting said corrected image.
- 18. The method of claim 17 wherein said portion of said raw image is substantially all of said raw image and wherein said corrected image less of said allowed aberration than that in said raw image.
- 19. The method of claim 17 wherein said portion of said raw image is used to generate a view being substantially free of said allowed aberration.
- 20. The method of claim 17 wherein said allowed aberration is an allowable amount of f-theta deviation.
- 21. A lens system comprising:
a first lens configured to accept light from greater than about 60-degrees from an axis-of-rotation; and one or more other lenses configured to receive said light accepted by said first lens and to focus said light on an image plane as a raw image, the lens system designed such that an increased amount of f-theta deviation is related to an enhanced lens system characteristic, said raw image capable of being processed to reduce said increased amount of f-theta deviation.
- 22. A catadioptric lens system comprising:
a transparent lens block comprising:
a first refractive aspherical surface configured to capture light from a 360 degree panoramic scene; a first reflective aspherical surface configured to reflect said light captured by said first refractive aspherical surface; a second reflective aspherical surface configured to reflect said light reflected by said first reflective aspherical surface; and a second refractive surface configured to transmit said light reflected by said second reflective aspherical surface out of the transparent lens block.
