Abstract
An imaging system includes first camera having negative distortion; second camera, second field of view of second camera being wider than first field of view of first camera, wherein first field of view fully overlaps with portion of second field of view, second camera having negative distortion at said portion and positive distortion at remaining portion; and processor(s) configured to: capture first image and second image; determine overlapping image segment and non-overlapping image segment of second image; and generate output image from first image and second image, wherein: inner image segment of output image is generated from at least one of: first image, overlapping image segment, and peripheral image segment of output image is generated from non-overlapping image segment.
Claims25
An imaging system comprising:
- a first camera having a negative distortion;
- a second camera, a second field of view of the second camera being wider than a first field of view of the first camera, wherein the first camera and the second camera are arranged in a manner that the first field of view fully overlaps with a portion of the second field of view, the second camera having a negative distortion at said portion of the second field of view and a positive distortion at a remaining portion of the second field of view;
- and
- at least one processor configured to:
- control the first camera and the second camera to capture simultaneously a first image and a second image of a real-world environment, respectively;
- determine an overlapping image segment and a non-overlapping image segment of the second image corresponding to said portion and the remaining portion of the second field of view, respectively;
- and
- generate an output image from the first image and the second image, wherein:
- an inner image segment of the output image is generated from at least one of:
- the first image, the overlapping image segment of the second image, and
- a peripheral image segment of the output image is generated from the non-overlapping image segment of the second image, the peripheral image segment surrounding the inner image segment.
A device comprising:
- a first camera per eye, the first camera having a negative distortion;
- at least one second camera, a second field of view of the at least one second camera being wider than a first field of view of the first camera, wherein the first camera and the at least one second camera are arranged in a manner that the first field of view fully overlaps with a portion of the second field of view, the at least one second camera having a negative distortion at said portion of the second field of view and a positive distortion at a remaining portion of the second field of view;
- and
- at least one processor configured to:
- control the first camera and the at least one second camera to capture simultaneously a first image and a second image of a real-world environment, respectively;
- determine an overlapping image segment and a non-overlapping image segment of the second image corresponding to said portion and the remaining portion of the second field of view, respectively;
- and
- generate an output image from the first image and the second image, wherein:
- an inner image segment of the output image is generated from at least one of:
- the first image, the overlapping image segment of the second image, and
- a peripheral image segment of the output image is generated from the non-overlapping image segment of the second image, the peripheral image segment surrounding the inner image segment.
