Abstract
According to various embodiments, the system and method disclosed herein process light-field image data so as to mitigate or remove the effects of pixel saturation in light-field images. A light-field image may be captured with a light-field image capture device with a microlens array. The light-field image may be demodulated, and then a recovered value for each saturated pixel of the demodulated light-field image may be obtained. This may be done by comparing a saturated value of each saturated pixel with reference values of reference pixels proximate the saturated pixel and, if the proximate pixels have a higher reference value than the saturated value, setting the saturated pixel to the reference value. This process may be carried out iteratively until recovered values are obtained for the saturated pixels. A demodulated, saturation-recovered light-field image may then be generated and displayed with the recovered values for the saturated pixels.
