1. A method for harmonizing a combined image, comprising: receiving an image from each of two or more cameras, the images from two of the cameras representing the same region in an overlap region; measuring pixel statistics of a predetermined number of predetermined pixels in the overlap region for the image of each of the two cameras; determining a difference in the pixel statistics Δ pixel of the image from each of the two cameras in the overlap region; calculating a correction factor K pixel , the correction factor K pixel being predicted to produce a reduction in Δ pixel of less than Δ pixel /2 when applied to the image of one of the two cameras; applying the correction factor K pixel in a hardware device acquiring the image, and receiving a further image from the two cameras.
