The subject matter herein generally relates to cameras.
Cameras are often mounted in electronic devices, such as mobile phones and tablet computers. Components of the camera are generally sealed within the electronic device. In humid environments, the components of the camera, such as a filter, may accumulate moisture or fog, which influences performance of the camera.
Implementations of the present disclosure will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. Additionally, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other word that “substantially” modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.
In one embodiment, the heating member 14 is a coil formed by bending a resistance wire, but is not limited thereto. In other embodiments, the heating member 14 may be other shapes as long as the heating member 14 is able to adequately heat the filter 40.
In one embodiment, each conductive circuit 15 is located on a bottom surface (not labeled) of the first receiving space 11 and on a bottom surface (not labeled) of the second receiving space 12 and extends along an inner wall (not labeled) of the through hole 13 between the first receiving space 11 and the second receiving space 12. Each conductive circuit 15 is electrically coupled to the heating member 14. Each conductive circuit 15 may be formed on the bracket 10 by laser direct structuring, but is not limited thereto. In other embodiments, the conductive circuits 15 may be formed from metal films adhered onto the bracket 10 and etched.
The lens 30 is partially mounted within the mounting hole 221. The lens 30 is driven to move by the voice coil motor 22 to focus the lens 30.
The filter 40 is received within the first receiving space 11 and covers the through hole 13. The filter 40 is mounted on the heating member 14 such that a periphery of the filter 40 is in contact with the heating member 14. The filter 40 is heated by the heating member 14 to dispel moisture or fog from the filter 40. In one embodiment, the filter 40 is substantially rectangular, but is not limited to be rectangular. In other embodiments, the filter 40 may be other shapes according to requirements.
The camera 100 further includes a protecting member 80. The protecting member 80 is substantially rectangular and covers over the lens 30 to protect the lens 30. In one embodiment, the protecting member 80 is made of transparent material.
In other embodiments, the connector 70 may be omitted, such that the circuit board 50 is electrically coupled directly to the external component.
In other embodiments, each conductive circuit 15 is formed and located within the bracket 10 and electrically coupled between the heating member 14 and the circuit board 50.
The camera 100 as described above uses the heating member 14 to heat the filter 40 to dispel moisture and fog from the filter 40, thereby improving performance of the camera 100.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
