  • Using a region restricted cleanup signal to bridge a signal level mismatch between a blue screen and an adjoining garbage matte
    Patent number: 8063991
    Abstract: A visible luminance step in a background scene, caused by a signal level mismatch between a matte signal level and a blue backing signal level, is significantly reduced by a soft edge transition region that raises the blue backing signal level up to the signal level of a garbage matte by using a cleanup signal restricted to the transition region. The soft edge formed by cleanup does not make subjects transparent, and actors may enter this zone with little loss of image quality.
    Type: Grant
