Abstract

A portable communication device having a camera functionality including a camera lens and a UV filter element moveable into or out of a position covering the camera lens. The device includes an apparatus for detecting a light feature associated with an ambient light condition. The UV filter is automatically moved into or out of a position overlying the camera lens based upon the data determined from the light feature associated with the ambient light condition.

Claims (19)

1. A portable communication device comprising:

camera circuitry for carrying out a camera related operation;

a camera lens operatively coupled to the camera circuitry to focus the camera lens;

a UV filter element moveable between a first position displaced away from the lens and a second position overlying the lens;

an apparatus for detecting a light feature associated with an ambient light condition; and

a processing circuit including logic to execute code to:

obtain light data related to the detected light feature associated with the ambient light; and

generate a command to drive the movement of the UV filter element into the first or second position based on the light data obtained from the apparatus,

wherein the apparatus for detecting a light feature associated with an ambient light condition is a UV sensor, and the UV sensor detects a UV level associated with the ambient light, and wherein the processing circuit drives the UV filter to the first or second position based on a comparison of the determined UV level relative to a threshold UV level.

2. The device of claim 1 , wherein the processing circuit associates the light data from the sensor with (i) an outdoor lighting condition, or (ii) an indoor lighting condition.

3. The device of claim 2 , wherein the processing circuit drives the movement of the UV filter into the second position overlying the lens upon a determination that the light data is associated with an outdoor lighting condition.

4. The device of claim 2 , wherein the processing circuit drives the movement of the UV filter into a first position displaced away from the lens upon a determination that the light data is associated with an indoor lighting condition.

5. A method for automatically positioning a UV filter relative to a camera lens on a portable network communication device having a lens and a camera functionality, the method comprising:

determining light data associated with an ambient light condition, wherein determining the light data comprises determining a UV level associated with the ambient light condition;

determining, based on the determined light data, if the UV filter element should be in a position (i) overlying the lens, or (ii) displaced away from the camera lens; and

controlling a mechanism to move the UV filter element into or out of a position overlying the lens, (i) moving the UV filter into a position overlying the lens when the UV level is above a threshold UV level, and/or (ii) moving the UV filter into a position displaced away from the lens when the UV level is below a threshold UV level.

6. The method of claim 5 , comprising:

associating the light data with (i) an outdoor lighting condition, or (ii) an indoor light condition; and

moving the UV filter into a position overlying the lens in response to the light data being associated with an outdoor lighting condition, or moving the UV filter into a position displaced away from the lens in response to the light data being associated with an indoor lighting condition.
