1. A method, the method comprising:

  • operating a first optical chain of a camera device including a plurality of optical chains to capture a first image of a first scene area using a first exposure time, said first optical chain having a first focal length;

    operating a second optical chain of the camera device to capture a second image of a second scene area using a second exposure time which is shorter than said first exposure time, said second optical chain having a second focal length which is longer than said first focal length, a time in which said second image is captured overlapping a time during which said first image is captured; and

    generating a composite image from said first and second images, said step of generating a composite image including performing a weighted combination of pixel values from said first and second images for at least a first portion of said first scene area which is overlapped by said second scene area as a function of whether the first portion of the scene area is an area of motion, said step of performing a weighted combination of pixel values including weighting a first pixel value of the second image corresponding to a first scene area which is an area of motion more heavily than a first pixel value in said first image corresponding to the first scene area which is the area of motion and summing the first weighted pixel value of the first image with the first weighted pixel value of the second image to generate a first pixel value of the composite image corresponding to said first scene area.
