Abstract: An encoder which encodes a picture includes processing circuitry and memory. Using the memory, the processing circuitry: splits the picture into a plurality of slice segments; encodes a plurality of blocks included in each of the plurality of slice segments; reconstructs the plurality of blocks encoded; adds, for each of the plurality of slice segments, control information to a header area of the slice segment, the control information being for controlling application of a filter to the slice segment; and applies, for each of the plurality of slice segments, the filter to a block which has been reconstructed in the slice segment, according to the control information of the slice segment.

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.
