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