ENCODING DEVICE, ENCODING PROGRAM, AND ENCODING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an encoding device, an encoding program and an encoding method that can avoid deterioration in picture quality.

SOLUTION: The encoding device is configured to encode macroblocks constituting a picture as an intra macroblock once in every peroid wherein a predetermined number of macroblocks among macroblocks constituting a picture are selected and encoded as an unexpected intra macroblock and other macroblocks constituting a predetermined picture are encoded as a non-intra macroblock predicted from macroblocks constituting a picture right before the predetermined picture in time series or an intra macroblock in every fixed period, the other microblocks being encoded as the non-intra microblock so that prediction from macroblocks which are not selected yet as an intra macroblock in a fixed period is not performed.
