1. In a light-field image capture device having a plurality of microlenses, a method for compensating for sensor saturation and microlens modulation, comprising:

  • in a processor, determining a flat-field response contour for each of at least one region of an image sensor;

    in the processor, generating a modulation image based on the at least one flat-field response contour;

    in the processor, generating a demodulation image from the modulation image;

    in the processor, receiving light-field image data;

    in the processor, applying the generated demodulation image to the received light-field image data to generate a demodulated light-field image; and

    outputting the light-field demodulated image on a display device.
