Abstract: Provided is an image encoding method which inhibits deterioration in processing performance for encoding while improving transmission efficiency. The image encoding method is for generating a bitstream by encoding a picture, and includes: sequentially encoding blocks included in the picture; deriving an encoding amount of a slice segment each time one of the blocks is encoded as a current block, the slice segment including the current block; determining whether the encoding amount derived is at least a threshold; and setting end information indicating an end of the slice segment in a position in the bitstream when the encoding amount is determined to be at least the threshold, the position corresponding to the current block encoded.

Abstract: The image encoding apparatus which encodes, on a per block basis, a current picture included in a moving picture includes: an encoder which outputs a first encoded stream including, in the following arrangement order, (i) slice data obtained by encoding a slice included in the current picture and including a plurality of block lines and (ii) a slice header including information indicating a code amount of each of the plurality of block lines; and an exchanger which exchanges arrangement positions of the slice data and the slice header in the first encoded stream.

Abstract: A moving picture encoding apparatus encodes a moving picture having an interlaced structure, and includes: a storage which stores fields as reference pictures; and an encoder which encodes a current field as a B-picture, using a first reference picture list which includes only one field in a same parity as the current field, and a second reference picture list which includes only one field in an opposite parity to the current field.
