A system and method for altering the characteristics of a display based on environmental data is disclosed. Exemplary embodiments provide a light sensor, an environmental processing unit which is adapted to receive electrical signals from the light sensor and generate an environmentally-reactive control signal (S.sub.a), an image signal processor which accepts S.sub.a and an encoded image signal (S.sub.e) and generates a pre-decoding image signal (S.sub.p), and an image signal decoder which accepts Sp and generates a decoded image signal for the display. The environmentally-reactive control signal (S.sub.a) may contain the instantaneous value of the desired display black level S.sub.b. Alternatively or additionally, the environmentally-reactive control signal (S.sub.a) may contain a signal linearity modification value.
