AUTOMATIC LENS FLARE DETECTION AND CORRECTION FOR LIGHT-FIELD IMAGES

摘要

According to various embodiments, the system and method disclosed herein process light-field image data so as to mitigate lens flare effects. A light-field image may be captured with a light-field image capture device with a microlens array and received in a data store. A plurality of flare-affected pixels may be identified in the light-field image. The flare-affected pixels may have flare-affected pixel values. Flare-corrected pixel values may be generated for the flare-affected pixels. Relative to the flare-affected pixel values, the flare-corrected pixel values may at least partially remove the lens flare effects. The flare-corrected pixel values may be used to generate a corrected light-field image in which the lens flare effects are at least partially corrected. The corrected light-field image may be displayed on a display screen.

1. A method for correcting a light-field image to remove effects of a first lens flare, the method comprising:
in a data store, receiving the light-field image after the light-field image has been captured by a light-field image capture device having a sensor and a plurality of microlenses; in a processor, identifying a plurality of flare-affected pixels of the light-field image that have been affected by the first lens flare, wherein the flare-affected pixels have flare-affected pixel values; in the processor, generating flare-corrected pixel values for the flare-affected pixels, wherein, relative to the flare-affected pixel values, the flare-corrected pixel values at least partially remove effects of the first lens flare; in the processor, using the flare-corrected pixel values to generate a corrected light-field image in which effects of the first lens flare are at least partially corrected; and on a display device, displaying the corrected light-field image.
