PURPOSE:To provide the removal system for noises due to the leak prediction of decoding corresponding to the high-efficiency encoding of an image using the leak prediction. CONSTITUTION:This system has a means 204 which finds an attenuation value of a predicted value by a leak coefficient on an encoding side for a signal encoded by using the leak prediction, a 'means 205 which generates an accumulated value of the attenuation value, and a means which adds the accumulated value to a prediction error signal, and removes the noises due to the leak prediction from the prediction error signal. Further, the means 205 which generates the accumulated value outputs the accumulated value as it is when the prediction error signal is '0' and initializes the accumulated value to '0' in other cases. |
