Abstract

A camera device comprising an image capturing element, one or more lens elements for projecting an object on the image capturing element, one or more spacer means for maintaining a predetermined distance between the lens and the image capturing element, and one or more lens substrates for carrying the lens, wherein the camera device further comprises an electrically variable focus polymer-stabilized liquid crystal lens.

Claims

1. A camera device comprising an image capturing element, one or more lens elements for projecting an object on the image capturing element, one or more spacer means for maintaining a predetermined distance between the lens and the image capturing element, and one or more lens substrates for carrying the lens, wherein the camera device further comprises an electrically variable focus polymer-stabilized liquid crystal lens.

2. A camera device in accordance with claim 1, wherein the electrically variable focus polymer-stabilized liquid crystal lens is mounted in between two lens substrates.

3. A camera device in accordance with claim 1, wherein the electrically variable focus polymer-stabilized liquid crystal lens is mounted on top of a lens substrate.

4. A camera device in accordance with claim 1, wherein the electrically variable focus polymer-stabilized liquid crystal lens is mounted directly on the image capturing element.

5. A camera device in accordance with claim 1, wherein the electrically variable focus polymer-stabilized liquid crystal lens possesses lens elements on both surfaces.

6. A camera device in accordance with claim 1, wherein two electrically variable focus polymer-stabilized liquid crystal lenses are present in the camera device, separated by one or more lenses.

7. A camera device in accordance with claim 1, wherein the electrically variable focus polymer-stabilized liquid crystal lens is provided with ITO layers on both sides for creating electrical contact.

8. A camera device in accordance with claim 7, wherein the connection of contacts is obtained by a conductive glue.

9. A camera device in accordance with claim 7, wherein the electrically variable focus polymer-stabilized liquid crystal lens is provided by ITO layers on both sides, wherein said ITO layers are structured in such a way that a part of each side of the liquid crystal lens lacks the ITO layer thereby creating areas which are non-conductive, wherein the electrical contact between the ITO layers is established by a conductive glue.

10. A camera device in accordance with claim 1, wherein the electrically variable focus polymer-stabilized liquid crystal lens is provided with ITO layers on both sides, wherein an electrical contact between these two ITO layers is obtained by a conductive glue and conductive element.

11. A camera device in accordance with claim 10, further comprising a printed circuit board, wherein the conductive element is a wire contacting with the printed circuit board.

12. A camera device in accordance with claim 1, wherein the electrically variable focus polymer-stabilized liquid crystal lens is provided with ITO layers on both sides thereof, wherein an electrical contact is established by providing non-conductive and conductive glues on both sides of the liquid crystal lens.
