ABSTRACT:
Systems and methods for adjusting image contrast are provided. An exemplary method for adjusting image contrast includes determining a format of a television signal and outputting in conjunction with the television signal a reference level. If the television signal has a first format, then the reference level is caused to be substantially equal to a luminance level representing a black color in the first format. However, if the television signal has a second format, then the reference level is caused to be substantially equal to a luminance level representing a black color in the second format.
