An encoding apparatus 100 performs intra-frame encoding or inter-frame encoding using a predetermined scheme, or performs an orthogonal transform on an image as one process in the intra-frame encoding or the inter-frame encoding. In order to perform the intra-frame encoding, the inter-frame encoding, or the orthogonal transform, various parameters to be specified by the encoding apparatus are specified as an abbreviated parameter which uses a number of bits less than the number of bits that is assigned by the specification. This enables to reduce the data amount of a parameter in the coded data.
