Abstract:
The present disclosure generally relates to a method and device for encoding a frame. The method includes the steps of determining a backlight frame from the frame, calculating a residual frame responsive to the frame and the backlight frame, and predictive-encoding of the residual frame using a predictor of the residual frame calculated from an imposed frame (IMF), where the imposed frame is a low-dynamic version of the frame to be encoded. The disclosure relates also a method and device for decoding at least one bitstream representing a frame.
