Abstract
Apparatuses, systems, and methods for producing non-rotationally symmetric optical aberrations. Such aberrations may be created by a removable attachment that may be attached to another lens, such as a spherical lens. Aberrations that appear to reproduce an anamorphic effect may be produced, yet the underlying camera system may remain a spherical camera system, and the capture mode may remain non-anamorphic.
Claims19
An attachment for use with a camera lens, wherein the attachment comprises a housing configured to connect with the camera lens and accommodate placement of a lens group therein, wherein the lens group comprises lens elements, and wherein the lens group is configured to induce non-rotationally symmetric optical aberrations in the camera lens without significant image compression in any axial dimension.
A method for inducing optical aberrations in a camera lens comprising:
- attaching a housing to a camera lens, wherein the housing comprises a lens group disposed therein including lens elements, and wherein the lens group is interposed between an object space and the camera lens;
- and
- processing an image from the object space through the lens group to induce non-rotationally symmetric optical aberrations in the camera lens without significant image compression in any axial dimension.
A camera system comprising:
- a camera lens;
- an attachment interposed between an object space and the camera lens, wherein the attachment comprising:
- a housing;
- and
- a lens group disposed within the housing comprising lens elements, wherein the lens elements are aligned with an optical axis of the camera lens, wherein the lens elements are fixed within the housing, wherein the lens group is configured to induce non-rotationally symmetric optical aberrations in the camera lens and not produce significant image compression in any axial dimension.
