1. A method of enhancing video images in a medical device, the method comprising:
receiving a first image frame and a second image frame from one or more image sensors;
generating first image sub-blocks by dividing the first image frame;
associating at least one curve to the first image sub-blocks based on one or more look-up tables;
identifying a target in at least one of the first image sub-blocks;
generating second image sub-blocks by dividing the second image frame based on the first image sub-blocks;
associating at least one curve to the second image sub-blocks based on the one or more look-up tables;
identifying the target in at least one of the second image sub-blocks;
generating histogram enhanced images of the target in the first image sub-blocks and the second image sub-blocks; and
generating a video image stream based on the histogram enhanced images of the target.
