Abstract
A system and method for filling light for video images are provided. The method may include: obtaining, by at least one video processing device, a first image including a plurality of reference pixels and is associated with at least one brightness direction; for each of the plurality of reference pixels, obtaining, by the at least one video processing device, a reference brightness value; identifying, by the at least one video processing device, a target brightness direction from the at least one brightness direction; for each of the plurality of reference pixels, determining a brightness enhancement multiplier for the reference pixel based on the plurality of reference brightness values and locations of the plurality of reference pixels along the target brightness direction of the first image; and modifying, by the at least one video processing device, brightness of the first image at least based on the brightness enhancement multipliers.
