Abstract
A method includes capturing an image of a lenticular display, generating a lenticular distortion map of the lenticular display using the image, and compensating for a lenticular distortion of the lenticular display using the lenticular distortion map. The lenticular distortion map is a dual-component lenticular distortion map and the image is a fringe pattern. The method compensates for the lenticular distortion by adjusting a swizzle function based on the lenticular distortion map.
Claims20
A method, comprising:
- capturing an image of a fringe pattern displayed on a lenticular display;
- generating a lenticular distortion map of the lenticular display using the image;
- and
- compensating for a lenticular distortion of the lenticular display using the lenticular distortion map, wherein the lenticular distortion map is a function of a lenticular display observation angle.

A method, comprising:
- capturing an image of a fringe pattern displayed on a lenticular display;
- generating a lenticular distortion map of the lenticular display using the image;
- and
- compensating for a lenticular distortion of the lenticular display using the lenticular distortion map wherein, the lenticular distortion map is a dual-component lenticular distortion map and the dual-component lenticular distortion map is generated using a parallel lenticular distortion map and a perpendicular lenticular distortion map.
1 more element
An apparatus, comprising:
- a lenticular distortion tracking camera;
- a lenticular display coupled to the lenticular distortion tracking camera, the lenticular distortion tracking camera configured to capture an image of a fringe pattern displayed on the lenticular display;
- and
- a processor coupled to the lenticular distortion tracking camera and the lenticular display, wherein the processor generates a lenticular distortion map of the lenticular display using the image and compensates for a lenticular distortion of the lenticular display using the lenticular distortion map, wherein the lenticular distortion map is a function of a lenticular display observation angle.
