Abstract

Methods and apparatus for providing a user of a camera information about the status of one or more lenses and/or providing a subject of a photograph an indicator of where to look during image capture are described. In some embodiments different sets of camera modules are used for taking photographs depending on user input and/or the distance to the objects to be captured. In various embodiments an indicator, e.g., light emitting element, is associated with each of the different sets of camera modules which maybe used to indicate where a subject should look during image capture by the corresponding set of camera modules. In some embodiment dirty lenses of the camera are detected and the user is notified of the dirty lenses through an audible and/or visual indication. In some embodiments the indication of which lens/lenses are dirty is provided by illuminating light emitting elements corresponding to the dirty lens(es).

First claim

What is claimed is:

1. A method of operating a camera, the method comprising:
activating a first light emitting device, on a face of a camera including multiple camera modules, to emit light to indicate a point on the face of the camera at which a subject of a photograph should look, said first light emitting device being one of a plurality of light emitting devices positioned at different locations on the face of the camera.

2. The method of claim 1 , wherein different ones of said light emitting devices are positioned between different clusters of camera modules.

3. The method of claim 1 , further comprising, prior to activating the first light emitting device:
operating the camera to select a first set of camera modules to use to take a first photograph, said first set of camera modules being from a plurality of different sets of camera modules in said camera; and
identifying said first light emitting device in said plurality of light emitting devices to activate based on which of said plurality of different sets of camera modules is selected to be the first set of camera modules, said first light emitting device being associated with the first set of camera modules.

4. The method of claim 3 , further comprising:
operating the camera to select a second set of camera modules to use to take a second photograph, said second set of camera modules being another set of camera modules from the plurality of different sets of camera modules; and
identifying a second light emitting device in said plurality of light emitting devices to activate based on which set of camera modules is selected to be the second set of camera modules, said second light emitting device being associated with the second set of camera modules.

5. The method of claim 3 , wherein said first set of camera modules is selected based on i) user input selecting a type of photograph to be taken or ii) a focus setting to be used.

6. A method of providing information about a condition of a camera including multiple lenses, the method comprising:
detecting one or more dirty lenses; and
displaying on a display device on a back side of said camera an image of a face of the camera including multiple lenses and an indication as to which of the multiple lenses of the camera are dirty.

7. The method of claim 6 , further comprising:
activating at least one light emitting device on the face of the camera associated with a dirty lens to emit light to signal that the lens is dirty.

8. The method of claim 7 , wherein activating at least one light emitting device on the face of the camera includes activating light emitting devices corresponding to multiple different dirty lenses to indicate which lenses are dirty while leaving light emitting devices corresponding to lenses which were not detected to be dirty unlit.

9. The method of claim 8 , further comprising:
after a period of time checking the camera lenses which were dirty to determine if they are still dirty; and
deactivating the light emitting devices associated with lenses which were previously determined to be dirty but are no longer determined to be dirty.

10. The method of claim 6 , wherein
displaying on a display device on a back side of said camera an image of a face of the camera including multiple lenses and an indication as to which of the multiple lenses of the camera are dirty includes:
displaying as part of said image at least three different lenses located at different distances from a bottom of said camera.

11. A camera device, comprising:
a plurality of camera modules;
a plurality of light emitting devices on the face of said camera, said plurality of light emitting devices including a first light emitting device; and
a light controller configured to activate said first light emitting device on a face of said camera to emit light to indicate a point on the face of the camera at which a subject of a photograph should look.

12. The camera device of claim 11 , wherein different ones of said light emitting devices are positioned between different clusters of camera modules.

13. The camera device of claim 11 , further comprising:
a selection module configured to select a first set of camera modules to use to take a first photograph, said first set of camera modules being from a plurality of different sets of camera modules in said camera; and
an identification module configured to identify said first light emitting device in said plurality of light emitting devices to activate based on which of said plurality of different sets of camera modules is selected to be the first set of camera modules, said first light emitting device being associated with the first set of camera modules.

14. The camera device of claim 13 ,
wherein said selection module is further configured to select a second set of camera modules to use to take a second photograph, said second set of camera modules being another set of camera modules from the plurality of different sets of camera modules; and
wherein said identification module is further configured to identify a second light emitting device in said plurality of light emitting devices to activate based on which set of camera modules is selected to be the second set of camera modules, said second light emitting device being associated with the second set of camera modules.

15. A camera including multiple lenses, comprising:
a dirty lens determinator configured to detect one or more dirty lenses; and
a display controller configured to control said camera to display, on a display device on a back side of said camera an image of a face of the camera including multiple lenses and an indication as to which of the multiple lenses of the camera are dirty.

16. The camera of claim 15 , further comprising:
a plurality of light emitting devices on the face of said camera, said plurality of light emitting devices including: i) a first light emitting device corresponding to a first lens and being positioned at a location closer to said first lens than to a second lens of said camera; and ii) a second light emitting device on the face of said camera corresponding to the second lens and being positioned closer to the second lens than said first lens; and
a light controller configured to activate at least one light emitting device on the face of the camera associated with a dirty lens to emit light to signal that the lens is dirty.

17. The method of claim 1 , wherein said point at which a subject of the photograph should look is one of a plurality of different points located between different camera modules.
