Methods and apparatus for implementing a camera device including multiple camera modules and which supports zoom operations are described. A plurality of moveable camera modules are included with the position of the moveable camera modules being controlled as a function of a zoom setting. One or more fixed camera modules are also included to facilitate image combining. A fixed camera module having a smaller focal length than the movable camera modules is used in some embodiments to capture a scene area including scene area portions which will be captured by movable camera modules. The image captured by the fixed camera module, with the small focal length, is used in aligning images captured by the movable camera modules during generation of a composite image. The camera may also include another fixed camera module, e.g., having the same focal length as the movable camera modules, for capturing the center of a scene.

1. A method of operating a camera device, the method comprising: controlling the position of a first camera module of said camera device as a function of a first zoom setting;capturing, using the first camera module, a first image while the first camera module is positioned at a first position corresponding to the first zoom setting;capturing using a fixed camera module of said camera device an additional image while said first camera module captures said first image;controlling the position of a second camera module of said camera device as a function of the first zoom setting;capturing, using the second camera module, a second image while the second camera module is positioned at a second position corresponding to the first zoom setting;controlling the position of a third camera module of said camera device as a function of the first zoom setting;capturing, using the third camera module, a third image while the third camera module is positioned at a third position corresponding to the first zoom setting;controlling the position of a fourth camera module of said camera device as a function of the first zoom setting; andcapturing, using the fourth camera module, a fourth image while the fourth camera module is positioned at a fourth position corresponding to the first zoom setting; andwherein said fixed camera module has a smaller focal length than the first and second camera modules and wherein said additional image includes a scene area captured by the combination of the first, second, third and fourth camera modules. 2. The method of claim 1, further comprising: generating a first composite image by combining said first, second, third and fourth images, said step of generating the first composite image including using said additional image to align said first, second, third and fourth images for purposes of combining the first, second, third and fourth images. 3. The method of claim 1, further comprising: operating a camera module position control module to move said first, second, third and fourth camera modules to increase the amount of overlap in the fields of view of said first, second, third and fourth camera modules in response to an increase in a zoom level setting; andoperating the camera module position control module to move said first, second, third and fourth camera modules to decrease the amount of overlap in the fields of view of said first, second, third and fourth camera modules in response to a decrease in the zoom level setting. 4. A method of operating a camera device, the method comprising: controlling the position of a first camera module of said camera device as a function of a first zoom setting;capturing, using the first camera module, a first image while the first camera module is positioned at a first position corresponding to the first zoom setting;capturing using a fixed camera module of said camera device an additional image while said first camera module captures said first image;controlling the position of a second camera module of said camera device as a function of the first zoom setting;capturing, using the second camera module, a second image while the second camera module is positioned at a second position corresponding to the first zoom setting;controlling the position of a third camera module of said camera device as a function of the first zoom setting;capturing, using the third camera module, a third image while the third camera module is positioned at a third position corresponding to the first zoom setting;controlling the position of a fourth camera module of said camera device as a function of the first zoom setting; andcapturing, using the fourth camera module, a fourth image while the fourth camera module is positioned at a fourth position corresponding to the first zoom setting; andwherein said first, second, third and fourth camera modules are moveable camera modules and wherein the fixed camera module has a focal length which is the same as the focal length of the first, second, third, and fourth camera modules and wherein said fixed camera module captures a center portion of a scene area of interest. 5. The method of claim 4, wherein said first, second, third and fourth images correspond to first, second, third and fourth scene areas, respectively, that at least partially overlap said center portion of the scene area of interest. 6. The method of claim 4, further comprising: generating a first composite image corresponding to said first zoom setting from said first, second, third, fourth images and said additional image. 7. The method of claim 6, further comprising: controlling the position of the first camera module as a function of a second zoom setting; andcapturing, using the first camera module, a sixth image while the first camera module is positioned at a sixth position corresponding to the second zoom setting. 8. The method of claim 7, further comprising: controlling the position of the second camera module as a function of the second zoom setting; andcapturing, using the second camera module, a seventh image while the second camera module is positioned at a seventh position corresponding to the second zoom setting. 9. The method of claim 8, further comprising: controlling the position of the third camera module as a function of the second zoom setting;capturing, using the third camera module, an eighth image while the third camera module is positioned at an eighth position corresponding to the second zoom setting;controlling the position of the fourth camera module as a function of the second zoom setting; andcapturing, using the fourth camera module, a ninth image while the fourth camera module is positioned at a ninth position corresponding to the first zoom setting. 10. The method of claim 9, further comprising: operating the fixed camera module to capture a tenth image, said tenth image being captured while said sixth, seventh, eighth and ninth images are being captured; andwherein said tenth image corresponds to the center portion of a scene area of interest corresponding to said second zoom setting and wherein said sixth, seventh, eighth and ninth images correspond to sixth, seventh, eighth and ninth scene areas, respectively, that at least partially overlap said center portion of the scene area of interest corresponding to the second zoom setting. 11. The method of claim 10, further comprising: generating a second composite image corresponding to said second zoom setting from said sixth, seventh, eighth, ninth and tenth images.
