1. A system programmed in a memory in a device comprising: a. a motion estimation module for performing motion estimation including generating a motion vector and a set of error values; b. a difference determination module for determining a difference between a minimum error of the set of error values and a remaining set of error values of the set of error values; c. a threshold module for comparing the difference to a threshold; and d. an indicator module for indicating low contrast in a scene based on comparing the difference and the threshold.
