IMAGE DECODING DEVICE, IMAGE ENCODING DEVICE, AND DATA STRUCTURE OF ENCODED DATA |
摘要 |
Memory required during decoding is reduced. A video image decoding device (1) is equipped with main direction deriving means (1453A) that references a prediction mode definition DEFPM(1), and from a prediction mode number, derives a main direction of a prediction direction corresponding to a prediction mode, and a gradient deriver (1453B) that references a gradient definition table DEFANG(1), and derives a gradient of the prediction direction. |
