1. An array camera, comprising:

  • a processor; and

    a memory connected to the processor and configured to store an image deconvolution application;

    wherein the image deconvolution application configures the processor to;

    obtain light field image data, where the light field image data comprises a synthesized high resolution image having a plurality of pixels, a depth map, and metadata describing the motion associated with a capturing device that captured the light field image data;

    determine motion data based on the metadata contained in the light field image data;

    generate a depth-dependent point spread function based on the synthesized high resolution image, the depth map, and the motion data, where the depth-dependent point spread function describes the blurriness of points within the synthesized high resolution image based on the motion of the capturing device and the depth of the pixels described in the depth map;

    measure the quality of the synthesized high resolution image based on the generated depth-dependent point spread function;

    when the measured quality of the synthesized high resolution image is within a quality threshold, incorporate the synthesized high resolution image into the light field image data; and

    when the measured quality of the synthesized high resolution image is outside the quality threshold;

    determine updated motion data based on the measured quality and the depth-dependent point spread function;

    generate an updated depth-dependent point spread function based on the updated motion data; and

    synthesize a new high resolution image based on the updated depth-dependent point spread function.
