Claim One:
1. A method for adjusting pixel sensitivities in an image capture device, comprising: capturing a frame of light-field image data representing a scene, the light-field image data comprising a plurality of pixels, each pixel having a plurality of values associated with different colors; for each color, determining a flat-field response contour for each of at least one region of an image sensor; for each color, generating a modulation image based on the at least one flat-field response contour; for each color, generating a demodulation image from the modulation image; applying the generated demodulation images to the captured light-field image data to generate a demodulated light-field image; applying a demosaicing operation to the demodulated light-field image; applying an automatic white-balance correction algorithm to the demodulated light-field image; estimating a chrominance of the scene illumination; adjusting sensor gain individually for each color, based on the estimated chrominance; capturing a subsequent frame of light-field image data, using the adjusted sensor gain for each of the colors; and storing the captured subsequent frame.
