Abstract:
1. A method for generating additional versions of video content, the method comprising: obtaining first histogram data for a first version of the video content adapted to be viewed in a first ambient lighting condition; obtaining a second version of the video content adapted to be viewed in a second ambient lighting condition; wherein the first and second ambient lighting conditions are different; obtaining second histogram data for the second version of the video content; generating a mapping from the second version of the video content to an additional version of the video content by performing a number of iterations of a progressive histogram matching algorithm, the number of iterations being fewer than a maximum number of iterations of the progressive histogram matching algorithm; wherein the number of iterations is determined based upon a signal from an ambient light sensor representing a third ambient light condition; wherein generating a mapping comprises determining a histogram transformation which morphs the second histogram data to become more like the first histogram data; and applying the mapping to generate the additional version of the video content from the second version of the video content; wherein the additional version is a recreation of the first version.
