1. A method for improving an image characteristic of a video stream captured by a video camera, the video stream including a plurality of image frames, the method comprising:
dividing, by a computing processor, each of the plurality of image frames into a plurality of regions;
determining, by a computing processor, a changed one of the plurality of regions of a second frame of the plurality of image frames in relation to a corresponding one of the plurality of regions of the first frame of the plurality of the image frames and an unchanged one of the plurality of regions of the second frame of the plurality of image frames in relation to a corresponding one of the plurality of regions of the first frame of the plurality of the image frames;
determining, by a computing processor, an improvement to the image characteristic for the changed one of the plurality of regions of the second frame of the plurality of image frames; and
applying, by a computing processor, the improvement to the image characteristic of the changed one of the plurality of regions of the second frame of the plurality of image frames, but not to the image characteristic of the unchanged one of the plurality of regions.
