Abstract

An optical lens has a light sensing die integrated into the optical lens. The optical lens is extended compared to a spherical optical lens such that the optical lens is elongated in order to allow for placement of the ambient light sensing die without causing any blocking or distortion of the optical lens. The shape of the optical lens and the placement of the ambient light sensing die is compensated for the change in shape compared to a spherical optical lens thus allowing for correct focal length parametrics.

Claims (7)

1. An optical lens for a camera utilizing ambient light sensing with an ambient light sensing die integrated into the optical lens of the camera, wherein shape of the optical lens is extended compared to a shape of a spherical optical lens such that a portion of the optical lens is laterally elongated relative to an optical axis of the optical lens, and the ambient light sensing die is located within the laterally elongated portion of the optical lens without causing any blocking or distortion of the optical lens and wherein the shape of the optical lens and the placement of the ambient light sensing die is compensated for by the change in shape compared to a spherical optical lens thus allowing for correct focal length parametrics.

2. The optical lens according to claim 1 , wherein the ambient light sensing die is fully encapsulated inside the optical lens.

3. The optical lens according to claim 1 , wherein a ribbon cable exits the optical lens and is connected to the ambient light sensing die to provide connectivity to the ambient light sensing die and an external terminal.

4. An optical lens assembly comprising a plurality of lenses having different lens shapes to form one cohesive lens, the optical lens assembly comprising a top optical lens according to claim 1 , wherein the ambient light sensing die is fully embedded into a laterally elongated portion of the top optical lens.

5. An optical lens assembly comprising a plurality of lenses having different lens shapes to form one cohesive lens, the optical lens assembly comprising an additional optical lens according to claim 1 placed next to the plurality of lenses, wherein the ambient light sensing die is fully embedded into a laterally elongated portion of the additional optical lens.

6. An optical lens according to claim 1 , wherein the optical lens has an oval shape.

7. The optical lens according to claim 1 , wherein the optical lens comprises an imaging lens of a camera.
