Abstract

An array lens module includes a housing, an image sensor with photosensitive area and a lens module installed inside the housing. The lens module is formed by at least two pieces glass lens. The first lens with the first imaging area and the second lens with the second imaging area are molded on the lens module. The image processor is respectively capturing the first image area and the second image area by a certain length-width ratio in the first imaging area and the second imaging area. A parallax between image in the first image area and image in the second image area is accordingly generated. The lens module is all-glass structure with a high transmittance and excellent achromatization performances.

First claim

What is claimed is:

1. An array lens module comprising:
a housing,
an image processor inside the housing,
an image sensor electrically connected with the image processor, the image sensor having a photosensitive area;
a lens module set on the image sensor; wherein
the lens module includes a first lens and the second lens keeping a distance from the first lens, the first lens having a first imaging area, the second lens having a second imaging area, at least part of the first imaging area and the second imaging area falling in the photosensitive area; wherein
the image processor captures images in the first image area and the second image area by a certain length-width ratio for generating a parallax between images in the first image area and the second image area; and
wherein the photosensitive area has two relatively parallel first side edges and the second side edge connected with the two first side edges, a connecting line between geometric centers of the first image area and the second image area is parallel to the first side edges.

2. The array lens module according to claim 1 , wherein the photosensitive area has two relatively parallel first side edges and the second side edge connected with the two first side edges, a connecting line between geometric centers of the first image area and the second image area is parallel to the side second edge.

3. The array lens module according to claim 1 , wherein the photosensitive area is a rectangle, both the first image area and the second image area are in circle.

4. The array lens module according to claim 3 , wherein the first image area and the second image area are respectively located at diagonal positions in the photosensitive area.

5. The array lens module according to claim 3 , wherein the corresponding areas to the first image area or the second image area on the image sensor are black and white photosensitive areas.

6. The array lens module according to claim 5 , wherein an infrared filter is installed between the second lens and the image sensor or between the first lens and the image sensor.

7. The array lens module according to claim 1 , wherein a first aperture and a second aperture are respectively formed at positions of the housing corresponding to the first lens and the second lens.

8. The array lens module according to claim 1 , wherein a surface of each glass lens is coated with antireflection antifogging coating, the antireflection antifogging coating at least covers the first lens and the second lens.

9. The array lens module according to claim 1 , wherein each glass lens comprises a first optical lens and a second optical lens isolated from the first optical lens, positions of the first optical lens and the second optical lens on any two pieces glass lens are corresponding to each other, the first lens comprises the stacked first optical lens, and the optical centers of the first optical lens are mutually aligned; the second lens comprises the stacked second optical lens, and the optical centers of the second optical lens are mutually aligned.
