Claim One:
1. A method performed by a processing system to provide a photometric normalization in an array camera having a reference imaging component and a plurality of alternate imaging components associated with the reference imaging component, the method comprising: receiving image data for a scene captured by the reference imaging component; receiving image data for a scene captured by each of plurality of alternate imaging components; determining a nominal parallax for image data of each of the plurality of alternate imaging components that translate information for a particular pixel in the image data of a particular alternate imaging component to a corresponding pixel in the reference imaging component; applying the nominal parallax of each particular alternate imaging component to the image data of the particular alternate imaging component; applying a low pass filter to the image data from the reference imaging component and the shifted image data of each particular alternate imaging component; and computing gain and offset parameters for each particular alternate imaging components from the low pass filtered shifted image data of the particular alternate imaging component and the low pass filtered image data of the reference imaging component.
