1. A method for color matching a first image and a second image, wherein a first region of the first image and a second region of the second image overlap, the method comprising: generating a first histogram of the first region; generating a second histogram of the second region; determining corresponding pixel values from the first and the second histograms; determining at least one parameter of an optoelectronic conversion function (OECF) that best matches the corresponding pixel values; and color matching the second image to the first image by applying the OECF with the at least one parameter to the second image.
