Abstract

A camera lens module includes an image sensor and a lens assembly. The image sensor includes a photosensitive chip defining a photosensitive path, wherein the lens assembly is coupled to the image sensor along the photosensitive path of the photosensitive chip. The lens assembly includes at least one optical lens module and an aperture member coupled at the optical lens module, wherein the optical lens module includes a lens barrel and at least an optical lens supported within the lens barrel. A relative position of the lens assembly with respect to the image sensor is adjustable for calibration and the relative position of the optical lens module is permanently fixed after calibration.

First claim

What is claimed is:

1. A camera lens module with a split lens, characterized by comprising:
an image sensor having a photosensitive path; and
a lens assembly, which includes an optical lens set, a lens barrel set, and an aperture member,
wherein the optical lens set includes at least two optical lenses, and the lens barrel set includes at least two lens barrels, and the at least two optical lenses are correspondingly installed within one of the optical barrel respectively to form at least two optical lens modules, and the aperture member is provided at a distal portion of the outmost optical lens module, and the optical lens modules are pre-assembled on the photosensitive path of the image sensor, and the assembling position of one of the at least two optical lens modules is adapted to be adjusted with respect to the position of the image sensor; and
wherein the lens barrel receiving the respective pre-assembled optical lens has at least a calibration channel which is provided in a barrel wall of the lens barrel for communicating an interior thereof with outside, wherein the calibration channel is aligned with respect to the optical lens pre-assembled within the lens barrel, such that the assembling position of the optical lens within the lens barrel can be adjusted through the calibration channel.

2. The camera lens module according to claim 1 , wherein the assembling position of the aperture member is adjustable with respect to the position of the optical lens module.

3. The camera lens module according to claim 1 , wherein the aperture member, the optical lens and the optical lens module are pre-assembled by an adhering element in a semi-solidified manner.

4. The camera lens module according to claim 3 , wherein the adhering element is a mixture glue comprising UV glue mixed with thermosetting adhesive, wherein the mixture glue is in a semi-solidified state under UV exposure and is solidified after heat treatment, and wherein once the adhering element is solidified, the whole camera lens module is permanently fixed in position.

5. The camera lens module according to claim 3 , wherein the assembling position of the optical lens within the optical lens module is arranged to be adjusted in at least one direction.

6. The camera lens module according to claim 3 , wherein the assembling position of the aperture member with respect to the top portion of the lens barrel is arranged to be adjusted in at least one direction.

7. The camera lens module according to claim 1 , wherein, when the lens assembly is installed within the camera lens module, the relative position of the optical lens module is adjustable with respect to up to six axes X, Y, Z, U, V, W of the camera lens module.

8. The camera lens module according to claim 7 , wherein the lens barrel provides at least an optical element to be calibrated therein for supporting at least one optical lens.

9. The camera lens module according to claim 8 , wherein the optical element to be calibrated is formed by a protrusion radially and inwardly extended from an inner barrel wall of the lens barrel.
