Abstract
MOVING IMAGE ENCODING DEVICE, MOVING IMAGE DECODING DEVICE, MOVING IMAGE ENCODING METHOD, AND MOVING IMAGE DECODING METHOD When an intra-frame prediction process at a time of 5 generating a prediction image is a horizontal one, an intra prediction unit adds a value proportional to a change in a horizontal directionofthe luminancevalues of pixels adjacent to the top of each prediction block to the luminance value of apixeladjacenttotheleftofthepredictionblocktodetermine 10 a result of the addition as a predicted value of a prediction image, whereas when the intra-frame prediction process at the time of generating the prediction image is a vertical one, the intra prediction unit adds a value proportional to a change in a vertical direction of the luminance values of pixels adjacent 15 to the left of the prediction block to the luminance value of the pixel adjacent to the top of the prediction block to determine the result of the addition as a predicted value of the prediction image. 20 Fig. 1
