    摘要: An image decoding method is provided for generating a predictive pixel value of a current picture to be decoded, and decoding the current picture using the predictive pixel value. The method includes a first parameter calculation step of calculating a first parameter corresponding to a distance between the current picture and a first reference picture; a second parameter calculation step of calculating a second parameter corresponding to a distance between the first reference picture and a second reference picture; a judgment step of judging whether or not a value of a third parameter calculated using a value obtained by dividing the first parameter by the second parameter is a value which is represented by a plurality of bits; a predictive pixel value generation step of generating a predictive pixel value of the current picture; and a decoding step of decoding the current picture using the predictive pixel value.

    摘要: A semiconductor for decoding coded image and audio data, which includes an audio processor that decodes coded audio data, and an image decoder that decodes image data. The image decoder removes coding distortion in pixels of two adjacent transform blocks which are motion-compensated, having a coded motion compensation error equal to zero, and are located inside a same macroblock. The image decoder includes a motion compensation block boundary detector that determines whether the motion compensation error of the two adjacent transform blocks located inside the macroblock is zero, and determines whether a boundary of two adjacent transform block is also a boundary of two adjacent motion-compensation blocks. The image decoder also includes a filter that removes coding distortion in pixels of the two adjacent transform blocks, and a selector that selects whether or not the filter removes the coding distortion based on the determination of the motion compensation block boundary detector.

    摘要: A moving picture prediction method for enabling a calculation amount and a storage capacity to be reduced in a prediction about a moving picture by scaling processing is provided. A method for predicting the value P of Time T from the value P0 of Time T0 and the value P1 of Time T1 includes a step of judging whether it is possible to generate a predictive value with a predetermined significant number of bits by scaling using Time T0, T1 and T (Step S90); a step of predicting the value P from the values P0 and P1 by scaling using Time T0, T1 and T when it is possible to generate a predictive value with the predetermined significant number of bits (Step S92); and a step of predicting the value P from the values P0 and P1 without using Time T0, T1 and T when it is impossible to generate a predictive value with the predetermined significant number of bits (Step S91).
