Abstract:
1. A method of coding a moving image, the method comprising: extracting, as a standard vector, a vector used to code a specific block that belongs to a coded field picture arranged chronologically adjacent to a field picture to be coded and arranged chronologically adjacent to a block to be coded; generating a predicted motion vector by scaling the standard vector on the basis of a temporal distance between the field picture to be coded and a second coded field picture specified by a reference index and referenced for the block that is to be coded and is included in the field picture to be coded and a temporal distance between a first coded field picture pointed by the standard vector and the coded field picture arranged chronologically adjacent to the field picture to be coded; and correcting the predicted motion vector on the basis of a parity of the field picture to be coded, a parity of the first coded field picture, a parity of the second coded field picture and a parity of the coded field picture arranged chronologically adjacent to the field picture to be coded and forming the corrected predicted motion vector.
