An arithmetic operation section or the like divides an image into a plurality of AUs and encodes the AUs to generate encoded streams of the plurality of AUs. A setting section sets 0 as pic_output_flag indicating that a decoded image obtained by decoding an encoded stream of an AU other than the last division AU from among the encoded streams of the plurality of AUs generated by the arithmetic operation section or the like is not to be displayed. The present disclosure can be applied, for example, to an encoding apparatus and so forth.
