Abstract
A picture coding apparatus includes a static area information calculating unit that calculates static area information indicating a size of a static area of which motion is smaller than a predetermined value for each of fields included in an interlaced picture, a reference field selecting unit that selects, as a reference field to be used to predict a field to be coded, one of a field having of the same parity as a field to be coded and a field having the opposite parity of the field to be coded, among fields previously coded, based on the static area information of the fields previously coded, and a coding unit that codes the field to be coded by using the reference field selected by the reference field selecting unit.
