1. A method for manufacturing an array camera device, the method comprising:

  • assembling an array of cameras comprising a plurality of imaging components that capture images of a scene from different viewpoints, where the plurality of imaging components comprises;

    a set of one or more reference imaging components, each having a reference viewpoint; and

    a set of one or more associate imaging components;

    configuring the array of cameras to communicate with at least one processor;

    configuring the processor to communicate with at least one display;

    configuring the processor to communicate with at least one type of memory; and

    performing a calibration process for the array of cameras, where the calibration process comprises;

    capturing images of a test pattern using the array of cameras, where each of the plurality of imaging components captures an image from a particular viewpoint;

    generating scene independent geometric corrections for reference image data captured by a reference imaging component using test pattern image data captured by the reference imaging component and data describing the test pattern using the processor;

    generating a corrected test pattern image for the reference imaging component based on the scene independent geometric corrections for the reference image data and the image of the test pattern captured by the reference imaging component using the processor; and

    generating scene independent geometric corrections for associate image data captured by an associate imaging component using test pattern image data captured by the associate imaging component and data for the corrected test pattern image using the processor; and

    loading calibration information into the memory.
